How often do you need to change the gearbox oil on a VAZ 2114? (solved)

It is worth noting that changing the oil in the VAZ 2115 gearbox is one of the most important aspects of car care. The oil ensures uniform lubrication of the rubbing elements of the transmission, and also serves as a coolant, removing temperature from the heated surfaces of the parts.

In today’s article we will talk to you about the reasons and periods for changing the oil in the VAZ 2115 gearbox. Let’s take a step-by-step look at the replacement process itself, and also figure out what kind of oil to pour into the “tag” gearbox.

Oil groups

Spectrol-Forward

For domestic VAZ 2115 cars, different groups of transmission oils are suitable, namely:

GL-4
GL-5

The first is suitable for gearboxes of front-wheel drive VAZs, and the second is universal and suitable for almost all domestic cars. Some people believe that GL-5 oils are better than GL-4, but this is not true.

These classes are simply different from each other, and none of them are better or worse than the other. For example, in some gearboxes, API GL-5 oils can have a detrimental effect on synchronizers, while API GL-4 is perfect for them. Oils for the VAZ 2115 GL-5 gearbox can be divided into three groups:

SAE 85W90 – mineral lubricants such as Rexol TM-5-18, Norsi and Lukoil TM-5-18;
SAE 80W90 – less thick mineral oils, including Wells TM, Spectrol-Forward, Texaco Geartex EP-C and others;
SAE 75W-90 – synthetics and semi-synthetics: Motulgear, Teboil EP, BP Energear SGX.

Oil selection

The cylindrical gears used in VAZ-2115 gearboxes are unpretentious in terms of the type of oil selected. Therefore, the transmission will feel equally good when filled with a mineral and synthetic composition. In order to economize, . The main selection criteria will be:

relative slip speed indicators;
parameters of specific loads acting on internal mechanisms.

Here you will need a liquid with a certain viscosity and additives. Make sure it contains anti-seize additives. They will create a special thin coating on the surfaces of rubbing parts, preventing scuffing and reducing overall wear. For the VAZ-2115, transmission compounds of 2 groups can be used:

Oils from the GL4 group are poured only into front-wheel drive models, while the second group has a universal purpose. Some consider the GL5 to be a better choice due to its high quality. But in fact this is not true. In terms of quality characteristics, they are the same. Only in the case of GL5 oils have a negative effect on synchronizers, which is not relevant for GL4 oils.

Under "VAZ-2115" from the GL5 group they are conventionally divided into categories:

These are mineral compounds. These include the products of Lukoil TM 5-18, Rexol and Norsi.
Also mineral mixtures, but less thick consistency. The preferred options would be Spectrol Forward, Wells TM, Texaco Geartex, etc.

An important point when choosing gearbox fluid will be viscosity.

Viscosity parameters

When choosing oils for the VAZ-2115 gearbox, be sure to take into account the viscosity indicators of the composition. Owners of domestic cars immediately remember the TAD-17I. But this transmission fluid is already a thing of the past. The current replacement for it was the composition TM5-18. If you live in the hottest regions, which is not typical for Russia and the CIS countries, a composition with a viscosity of 140 SAE may be suitable for you. But generally our climate is much cooler, which is why we need to focus on viscosity at moderate ambient temperatures.

All-season oils are well suited for VAZ-2115. Their viscosity parameters are as follows:

85W90;
80W90;
75W90.

The first type does not perform very well in the harsh Russian winter, so it is not suitable for certain regions. The remaining two options for transmission fluids are fully justified; they can withstand both the sultry summer heat and severe winter frosts. Regarding API classification, for the fifteenth model from AvtoVAZ, the best solution would be GL4 or GL4/5. The use of GL5 is not recommended, since such compounds accelerate wear of synchronizers.

If you plan to fill in a special transmission fluid, aim closer to the viscosity parameters 75W80. If you are not afraid to pour motor lubricant into the box, then 10W40 or 15W40 will suit you. The manufacturer itself advises AvtoVAZ to fill in TM4-12 with a viscosity of 80W85. This is a great solution, but finding the original will be quite problematic. The opinions of experts and the plant differ somewhat, since the official documentation mainly indicates the API class GL4/5 or GL5. Whom to believe, decide for yourself.

Novoil Super T;
Kinetic from Rosneft;
Super T-2;
Super T3;
Transaxle Oil produced by Shell brand.

Back in 1996, the manufacturer introduced a special gearbox oil for the VAZ-2115 called Rexol T. It had a viscosity of 80W85 and an API class of GL4. After 2 years, the plant began to recommend Lukoil TM4 with the same viscosity. It is possible to find oils recommended by the manufacturer. The recommended gearbox oil meets the requirements of the VAZ-2115, but is not a single alternative solution. The range of ingredients is impressive. The unpretentiousness of the domestic car and its gearbox allows you to choose the composition from a wide variety.

Car owner experience

On various forums, almost every VAZ-2115 car owner told what kind of oil he poured into the gearbox and what should not be poured. Based on the experiences of other people, you can draw objective conclusions for yourself. There are several oils that are in highest demand. This is about the question of which gear oil is best to pour for the VAZ-2115 gearbox if problems arise with the purchase of the original one recommended by the manufacturer.

TNK 75W90. An oil with good performance characteristics that allows you to confidently manipulate the gearbox. Its main advantage is accessibility. Among all the options presented, this is the cheapest composition.
GetribeOil EP with viscosity 75W90. This is an excellent gear lubricant produced by the famous Shell brand. Although the real properties and characteristics are comparable to the composition from TNK, at a higher cost of Shell.
with similar viscosity. If the winter is very harsh, the composition may freeze slightly. But under normal conditions it demonstrates its best qualities. In terms of price, this is somewhere between the options presented above.

We figured out the parameters, main characteristics and manufacturers. Now we focus on the need to buy gearbox fluids only in trusted places, in certified stores. The main problem of spontaneous markets and private sellers, who often offer oils at lower prices than in stores, is the high probability of encountering counterfeits. Many well-known brands suffer from an abundance of counterfeit products sold under their name. Therefore, try to avoid dubious markets and buy from those you trust.

What kind of oil to pour into the box of a VAZ 2115

Considering the factory indications that there is no need to change the transmission fluid, the manufacturer does not provide a list of brands that have been tested with this unit and have passed factory tests. Moreover, in fact, the operating manual does not contain the name of the VAZ 2115 gearbox oil recommended by the manufacturer. Accordingly, the owner must independently decide on the type of substance, depending on his financial capabilities and the nature of the use of the machine. There are 3 types of these products on the market:

Mineral substances enjoy relatively low popularity due to the lack of modern additives in the composition, as well as due to mediocre properties in comparison with competitors. These products have, in addition, only two advantages: low fluidity, which is less likely to lead to the extrusion of the substance through the seals at sub-zero temperatures, as well as low cost compared to competitors. Also, certain advantages include a small chance of purchasing counterfeit products, since for unscrupulous manufacturers the production of cheap products is unprofitable.
Semi-synthetic substances are more popular compared to natural mineral compounds due to better characteristics, as well as the presence of modern additives. In addition, these lubricants meet modern quality standards that are developed for modern transmissions. In terms of cost, semi-synthetics are superior to mineral compounds, but are rarely popular among manufacturers of counterfeit products. Possessing low fluidity, such compounds are common among owners whose transmission mileage has exceeded 150 thousand kilometers.
Synthetic materials have the best washing and cooling properties among all transmission oils. Such materials are produced almost entirely from modern additives; they allow long-term protection of the main components and assemblies of the box from natural wear. However, in terms of its cost, this composition is significantly ahead of its competitors, also having a high turnover rate. Thus, if there is fogging or microcracks in the crankcase, the composition will most likely begin to leak heavily from the transmission system.

How to change the oil on a “tag”

To begin, you will need to arm yourself with the following tools:

wrench 17 or socket;
a container into which the old oil will be drained (this can be a five-liter bottle or an empty canister);
an empty plastic bottle of one and a half liters;
work gloves;
with a knife;
lift;
work clothes;
a special stand (it is placed under the car);
3.5 liters of new GL-4 class oil, which is not intended for gearboxes;
a sheet of plywood, which will be used instead of bedding if the floors in the garage are poured with concrete or laid with steel;

Changing the oil in the VAZ 2115 gearbox is also carried out on an inspection pit, but we will consider the usual option on a jack. Let's get started:

Using a knife, cut out the side of the canister (you get a kind of container for draining the oil);

Oil drain container

we warm up the gearbox (for this you need to drive at least ten kilometers and thus the gears will disperse the heated oil throughout the entire gearbox);
lift the right side of the car onto the lift;
We place a block under the car, on which we lower the car.

Important. It should be remembered that under no circumstances should you work when the car is on a jack.

This applies not only to the oil change process, but also to any other type of activity.

We place a sheet of plywood on the concrete floor of the garage so that most of it fits under the car;
put on gloves;
we climb under the car, taking with us an empty canister and a key for seventeen;
We find a cutout under the oil plug (it is not found on all protections).

VAZ 2115 gearbox drain plug

Important. It is worth remembering that if the cutout is not detected, then most likely you will have to remove the engine protective shell

take a metal brush and clean the plug;
the space around the plug is also cleaned with a rag;
a container or canister-bath is placed under the drain;
unscrew the plug with a seventeen key;
wait about fifteen minutes until the oil is completely drained, and screw the plug into place;
take a plastic bottle and a knife;
cut out the bottom of the bottle;
remove the air filter and intake pipe, first removing the terminal from the sensor that regulates the air flow;
the throttle clamp and crankcase gas pipe are also unscrewed;
then the inlet assembly is completely removed;
the oil dipstick on the gearbox is pulled out (this dipstick is located in the upper part, closer to the car interior);
We install the neck of the bottle in place of the dipstick like a funnel;

Filling the gearbox of a VAZ 2115 with oil

Advice. It is advisable to fill no more than two liters at first. Then check to see if the drain plug under the car is leaking. It is advisable to wait ten minutes and then continue adding oil.

after this you need to put the protection in place;
add the rest of the oil (in total there should be 3.2 liters of oil in the VAZ 2115 gearbox).

It is recommended to add oil using the dipstick. They check the oil level, which should be in the middle, between the MIN and MAX marks on the dipstick. It is advisable that the transmission be in neutral. After adding oil and completing all work, it is recommended to drive the car 15-20 kilometers. After this, check the oil again, waiting about ten minutes. Changing the oil in the VAZ 2115 gearbox, video of the process - the procedure is not complicated. But it will require a little skill and the necessary knowledge.

Gearbox dipstick VAZ 2115

Armed with the information provided above, it is possible to change the VAZ 2115 gearbox oil using photo and video instructions with your own hands without much difficulty. The presented step-by-step instructions introduce the reader to all the basic secrets of changing the oil. Secrets and some important points also help the novice motorist do everything without much difficulty. And the most important thing is the high price, which can be significantly reduced, because services of this kind in car services are very expensive.

Replacement procedure

To change the oil in the VAZ-2115 gearbox, you have everything ready. Therefore, you can safely begin this procedure. The presented instructions for changing the oil will make you clearly understand that there is nothing complicated here. All work can be easily done with your own hands without outside help. If you do not want to take risks or are afraid to service the transmission yourself for the first time, it is better to trust trusted people from a good car service center. But practice shows that the vast majority of car owners do well in garage conditions. Therefore, do not be afraid, but start working.

To change the working fluid in the gearbox, it is better to have an overpass or inspection hole at your disposal. Many garages have it, so there shouldn’t be any problems with access to the bottom of the car.

If you go by the dipstick, then for the VAZ-2115 it is optimal when the level is 4 - 5 millimeters above the o. After all the procedures performed, when the drained liquid has already cooled down, be sure to check its sediment. If there are problems with the gearbox, which the car owner may not be aware of due to the still normal behavior of the transmission, metal shavings are found in the sediment. This is a dangerous sign indicating excessive wear of the elements. As a preventative measure, special additives can be used. If the problem is too serious and the chips appear again during the next service, it makes sense to contact a car service center to disassemble and repair the unit.

The oil change procedure should be approached carefully and carefully, because as soon as the instructions are strictly followed, the entire unit will be guaranteed long-term, and most importantly, stable operation. The price of such work will depend on where you perform it, as well as what spare parts (oils - approx.) you will purchase. Remember that they must be carried out every 60 thousand kilometers.

Manual transmission oil change period and required volume

The manual for the VAZ 2114 car says that the transmission oil must be changed every 60 thousand kilometers. To avoid gearbox breakdowns, you should:

Observe the timing of oil changes in the manual transmission on the VAZ 2114;
Fill in the required volume of oil, observing the liquid level;
Use only a high-quality product to change lubricant;

The instructions indicate that the volume of oil in the manual transmission in the VAZ 2114 is approximately 3.3 liters of mixture. If such signs of malfunction appear as difficulties in shifting gears, noise in the operation of the gearbox, we can talk about repairing the manual transmission. To avoid serious damage, it is necessary to monitor the condition of the lubricant and its level.

The oil for the VAZ 2114 should be changed in a manual transmission when the following symptoms appear:

Recommended vehicle mileage;
Operating conditions and load of the vehicle;
Technical features of manual transmission;
Long idle time of the car;
Poor lubricant condition;
Presence of mechanical chips in the transmission sump.

By following the recommendations of car maintenance specialists, you can avoid serious breakdowns of the manual transmission, which will lead to expensive repairs.

Oil change in Lada

A domestic VAZ car requires close attention and timely maintenance. Changing the oil in the engine and gearbox is a basic procedure that is carried out every 10-20 thousand kilometers traveled, regardless of the condition of the car or its operating conditions. If this procedure is not followed, then disruptions in the movement of the machine will be noticeable - vibration, jerking, and excess noise. Particular attention should be paid to the condition of the lubricant for vehicle owners over 8 years old.

Replacement and useful recommendations

The period for changing gearbox oil for VAZ cars is described in detail in the manufacturer's official instructions. It says that the fluid must be changed every 60 thousand kilometers. There are other recommendations that every driver needs to heed.

During operation, it is necessary to constantly monitor the level at which the oil is located inside the gearbox.
Transmission oils should be used only of high quality, recommended by the manufacturer.
Change the transmission fluid in a timely manner as soon as the need arises.

The same official manual indicates exactly how much oil to fill. The minimum required quantity is 3.3 liters.

It is necessary to carefully select not only the composition itself, but also its packaging for the checkpoint. Typically, such liquids are sold in canisters with a volume of 1, 3 or 5 liters. Increasingly, there are proposals to sell bottled oil directly from barrels. This allows you to profitably purchase only the amount of lubricant that is actually needed. The main thing is to pre-purchase the composition in small quantities to check its quality. Otherwise, you will have to spend more on repairing the box later.

Replacement frequency

If we take into account the official AvtoVAZ regulations, then on the gearboxes of their model “2115” it should be done every 60 thousand kilometers traveled. Or once every 4 years, if the car has not covered the specified distance. The information presented is completely true. Only in case of increased loads during vehicle operation is it necessary to reduce the frequency. AvtoVAZ perfectly understands the real conditions in which cars have to be. Therefore, it focuses on the poor condition of roads, climate and quality of fuel being poured, which also affects gearboxes.

If the gearbox wears out more intensely, which usually happens when the vehicle is operated under increased loads and in harsh climates, then reduce the replacement period to 40 - 50 thousand kilometers. When selecting transmission oil, pay special attention to temperature indicators. Timely replacement of the oil in the gearbox on a VAZ-2115 car will extend its service life, prevent premature wear and serious breakdowns.

When do you need to change the oil in a VAZ 2115 manual transmission?

The VAZ 2115 model is a logical continuation of the VAZ 21099 model, with some stylistic and technical changes. This model entered the market in 2001 and during production until 2011 it managed to sell 600 thousand copies.

The VAZ 2115 is equipped with a classic 5-speed gearbox, which was developed in the late 80s and early 90s. In terms of its design, it appears to be a classic system with a flywheel and gear shift clutches. During operation, no critical comments or major shortcomings were identified. The declared service life of the box is 150 thousand kilometers, but with proper care, constant prevention, and in the absence of excessive loads, overcoming this milestone will not be difficult.

Which oil to choose for the VAZ 2114 gearbox?

The driver will love the car provided that the main components of the car work perfectly. The driver knows in advance how much oil to pour into the engine, variable gearbox, and drive axles. But not always, especially beginners, know what type of lubricant to buy, for example, for a variable speed gearbox 2114.

The manufacturer helps you make your choice by offering to purchase products from a short list consisting of three items:

lubricating consistencies with a mineral base;
synthetic oils;
oils, made half of synthetics.

A rational conclusion can be drawn from the above list. There are many good offers on liquid platforms. Following the recommendations of the KOSSS102 channel, it is rational to buy the specified product. Transmission lubricant used for engine valves is suitable.

The fact is that the technical characteristics of the interaction of the elements with each other of the variable speed box and the cam mechanism of the motor distribution unit are similar in terms of abrasion coefficients.

Oil brands for gearbox 2114

In specialized stores, oils with a high degree of liquidity are always available. Sold in convenient containers with different volumes of lubricant product capacity.

Synthetic oil 75W-90 is in good demand. Well protects articulated parts from premature abrasion in heat and cold.
Semi-synthetic 85W-90 is recommended for cars with high mileage.

The lubricant product is packaged in convenient-to-use containers according to the number of liters. Since one oil fill during maintenance requires more than three liters, drivers tend to buy for future use.

A container that holds 8 liters of liquid lubricant is considered a running container. A certain number of motorists may be surprised, they say, why buy such a quantity of consumables. There are different ways to respond to skeptics.

Others cite work commitments that do not allow them to frequently visit specialized stores. It is more profitable to buy a large container with a guarantee of systematic refilling of the lubricant product into the crankcase of the 2114 gearbox than to run around the store looking for oil.

Others always buy something for future use on purpose: they pour as much into the 14th as liters are required. Some drivers change the lubricant after 30 thousand kilometers. In a word, both are individually right.

What kind of oil to fill in the gearbox on a VAZ 2114

Now you need to choose which oil you want to buy for the VAZ-2114. A mistake cannot be made here, since a fluid that does not correspond to a specific gearbox can lead to breakdown or incorrect operation of the part. So, you need to understand which oils you need to buy in the store and which ones the car manufacturer advises you.

There are a few things you need to consider when choosing new transmission fluid:

What type of gearbox do you have: manual or automatic?
What are the weather conditions in your region?

In stores that help in car maintenance, the choice of oils is quite large: synthetic, semi-synthetic and mineral technical oils. It’s definitely not worth taking the latter type, because it has very low characteristics and is often accompanied by poor quality. We recommend choosing synthetic oil, as it copes well with technical tasks, and there is a good review about it.

The problem is different, synthetics are expensive and not everyone can afford them. As a replacement, you can consider a semi-synthetic fluid; it has good characteristics at a fairly affordable price. If you turn to experienced drivers, they advise buying either synthetics 75w - 85w, or semi-synthetics 85w-90w. Do not try to take oil that is characterized by too high a viscosity. This may prevent lubrication and further rotation of the gears!

How to fill oil into a VAZ 2115 box

The procedure for changing the oil of a VAZ 2115 with your own hands is carried out in several stages:

First you need to lift the car on a lift and remove the metal protection of the engine crankcase and gearbox.
After this, unscrew the oil filter and the special drain bolt and remove the waste material.
After draining the spent substance is completed, it is necessary to use a simple funnel to fill in new material through a special filler neck, which is located in the upper part of the engine compartment on the gearbox housing.
If the overflow is above the mark indicated on the plastic dipstick, the excess volume must be drained by unscrewing the oil filter.

After the change procedure, it is necessary to check the performance of the gearbox by alternately switching all gearbox modes in a standing position. In this case, extraneous sounds arise, the selector lever should switch without additional effort, there should be no grinding or humming sounds, and there should be no manifestation of other negative factors.

Level and top up

As the vehicle is used, all fluids are gradually consumed. In the case of a transmission, this does not happen as quickly as with gasoline or oil in the gearbox. But you definitely need to monitor the level. The gearbox of VAZ-2115 vehicles has a special dipstick, access to which is provided through the engine compartment. To make your task easier, you can remove the air filter housing. It gets in the way a little. Manipulations for checking the level are elementary and correspond to the principle of monitoring fluid in the engine crankcase. You need to remove the dipstick, wipe it dry with a rag, insert it back and pull it out again. By the location of the oil film on the dipstick, you will see at what level the fluid is now.

If your version of the gearbox does not have a dipstick, which is typical for old-style gearboxes, you will have to use your eye and fill it to the level of the filler neck. This ensures the right amount of lubrication in the transmission housing. The VAZ-2115 gearbox has its own design features that do not allow it to operate for a long time if the level of transmission oil is insufficiently high. It's all about one gear. It is located higher than the others, which is why when the amount of oil is reduced, the lubricant does not reach it. This gear is responsible for 5th gear. Therefore, be sure to periodically check and add oil. Topping up is carried out through the filler hole from the engine compartment. Maintain a consistently high oil level in the gearbox of your VAZ-2115 so that the box works without crunching and can last as long as possible.

As you can see, it is not difficult to figure out how to check the oil level in the gearbox. In this regard, the VAZ-2115 designers did a good job, since car owners themselves can carry out a number of simple and fairly important repair and maintenance work with their own hands.

Checking the amount of oil in the gearbox

Always check the transmission oil level, and even if you just recently filled in new fluid, you should not forget about it, because the oil level always drops and you need to keep an eye on it. Even a slight decrease in the required volume can lead to a number of difficulties and various breakdowns, due to which the gearbox will cease to function normally. Newbie drivers often don't know how to check the fluid level in their car. Let's take out some pieces of paper and start writing down our tips!

What does a dipstick look like for checking gearbox oil?

A guide on how to understand how much oil is in the dipstick:

First, open the hood and look at the entire space under it to find out where the dipstick is located.
Remove the dipstick, wipe and clean it very diligently and carefully, completely removing old oil stains from the dipstick.
Use a rag for cleaning! It is free of lint and will not end up in your transmission fluid.
Just put the dipstick back and be patient for a couple of minutes.
Remove the dipstick again and carefully examine the location where the oil mark was located. On the outer part of the dipstick you will be able to see the possible maximum and minimum marks.
It is advisable that the oil mark be at the possible maximum mark, since the manual transmission has a gear that is responsible for the operation of the fifth gear, and it is located slightly higher than the others. To ensure the operation of this part, it is necessary that the oil level is at maximum.

Draining the oil from the gearbox

We arrive at the service point (you need to warm up the oil in the box after driving 2-4 km).
We park the car on the overpass.
We remove the protection.
We put it on the handbrake and support the wheels with boots for reliability.
We remove this rubber cap and clean it. Clean the hole that appears with a metal brush.
Remove the dipstick for checking the oil level in the gearbox. (Models before 2003 do not have a dipstick for checking the oil level; in this case, unscrew the oil filler plug, which is located on the right.
Place a container under the oil drain hole.
Take the key to “17” and unscrew the oil drain plug.
Wait about 15 minutes until all the oil has poured out.

IMPORTANT! The oil level should be at the max mark on the dipstick, but if you feel difficulty engaging 5th gear or a hum when driving in 5th, then try adding a little more oil above the max mark. The fact is that 5th gear is the highest and the oil level does not always reach it.

How is the volume of lubricant in the 2114 gearbox determined?

The automobile plant sends its products to liquid specialized sites with a set of instructions for operating the vehicle. Instructional materials regarding transmission units contain specific information.

The practice of operating a car of this modification has shown that the factory instructions cannot be an axiom when replacing a lubricant product. Scheduled and extraordinary maintenance (TO) require less lubricant. That is, a smaller volume of oil is required to be poured into the box. Drivers have empirically determined that it is enough to add 200 milliliters below the factory norm.

The a priori filling of oil by a plant that produces cars of the specified brand is calculated especially accurately. The lubricating fluid has good adhesion. Subsequently, covering the surfaces of the shafts and gears, settling on the walls of the box body, part of the lubricant product remains on these elements during intensive use. A significant portion of the oil in the VAZ 2114 gearbox remains in the form of a thin film. It cannot be drained when refilling.

They say that butter cannot spoil bread. In relation to food, a capacious definition. But not for pouring oil into the transmission unit of a car. When heated, any liquid increases in volume. At the same time, quality indicators decrease. The lubricating product loses its protective properties against abrasion of rubbing parts, contributing to their rapid wear. In short, the VAZ 2114 gearbox should not contain excess lubricant or significant underfilling

To extend the service life of an important transmission unit, you need to know the exact volumes of oil to be filled

Useful instructions will be productive during a certain operational period of the unit. The fact is that during long-term operation, the volume of oil poured into the VAZ 2114 increases significantly due to wear of rubbing parts. They wear out. Particles of waste metal pass to oil mixtures, raising their level. To balance the balance, add not 200 milliliters of lubricant, but 50 or 100.

In principle, the increase in oil level depends on the gear shift frequency. The more often the driver uses the speed change lever, the more intensively the gears, shafts, and splines of the vehicle transmission unit wear out.

Oil draining process

General view of the gearbox

It is quite easy to completely drain the oil from the VAZ-2114 gearbox. Work must be done immediately after the trip to reduce viscosity. This is due to the fact that it is heated and the density is reduced.

Location of the gearbox drain plug

So, let's consider the sequence of actions aimed at draining oil from the gearbox:

We install the car on a viewing hole or lift.
First, the breather is cleaned.
Then you need to unscrew the oil dipstick.
Place a container to drain the oil.
Unscrew the drain plug.
We wait until the oil drains completely.
In order to fill in new oil, you need to take a funnel and insert it into the hole for the dipstick.
We carry out the assembly in the reverse order.

Oil plays many roles in the functioning of the gearbox. So, in order to understand why it is needed, let’s consider the main properties:

Chemical. They play the role of a lubricating fluid, which is necessary for the normal functioning of the components and parts of the car. So, if there was no oil, parts would begin to wear out due to heat and friction, which in turn would lead to the fact that most products would not reach their service life.
Physical. Since the transmission generates a lot of heat when operating, it needs somewhere to go. Thus, oil is a kind of heat absorber that prevents the spare parts from heating up inside the gearbox housing. Also, its lubricating properties form a kind of film, which reduces the degree of wear of products to a minimum.
Technical. These are mixed properties of physical and chemical, namely the prevention of harmful effects on the structure as a whole and its main elements. These properties prevent the occurrence of metal shavings, corrosion and other technical faults.

This is what the oil drained from the gearbox on a VAZ-2114 looks like. Mileage 55,000 km. It still looks like

If the oil loses its properties, then the entire structure and individual elements begin to wear out faster.

Selection of gearbox oil for a VAZ 2110

Changing the oil in a VAZ 2110 gearbox requires compliance with basic rules, compliance with which will ensure uninterrupted operation of the vehicle for a long time.

Therefore, it is important to pay special attention to the purchase of liquid

Experts recommend first of all focusing on the originality of the product, and not on the brand. Many automotive suppliers sell low-quality counterfeits under the name of leading brands (Castrol, Mobil, BP). Such negligence on the part of sellers can result in negative consequences for the owner

It is also important to purchase products from official distributors or suppliers with successful experience in the market. A big plus is reviews from car enthusiasts on specialized forums.

Their life experience will help you avoid common mistakes.

It is necessary to select oil for the VAZ 2110 gearbox based on several factors, namely: climatic conditions and the season in which the driver operates the car.

The stores offer lubricating fluids made from:

mineral components;
synthetic materials;
semi-synthetic materials.

Experienced auto mechanics recommend synthetic oil for the VAZ 2110 gearbox, which allows you to effectively use the car even in particularly unfavorable temperature conditions. But the cost of this type of liquid is higher than semi-synthetic. Therefore, for owners who are trying not only to buy a good product, but also to save money, the last option is suitable. Do not forget that it is forbidden to use mineral oil after using two other lubricants.

Before considering the replacement process itself, you should understand the possible reasons for this need. In addition to periodic updating due to the 30 thousand mileage of the car, this is affected by a decrease in the performance of the car or the use of low-quality oil, which causes an atypical hum when changing gears.

What oil is better to use?

To choose the right fluid for the VAZ 2115 gearbox, you need to take into account the factory recommendations. According to the service documentation, it is necessary to fill the box with special gear oil that meets SAE 80W-85 and API GL-4 or GL-5 approvals. This type of liquid is present in the product range of any company that produces lubricants for cars.

At the factory, when the car is released, TNK or Lukoil brand oil is poured into the box. These same fluids are among those recommended by the manufacturer for the VAZ 2115. When operating a car in winter, many owners try to use synthetic oils that meet the requirements of SAE 75W-80 or 75W-90. The use of such lubricants significantly reduces the operating noise of the unit and facilitates gear shifting at negative air temperatures - below minus 16–18 degrees.

Among the most common oils for the VAZ 2115 are the following (in ascending price):

Lukoil TM 4–12 80W-85;
THK Trans KP 80W-85;
ZIC GF 75W-90;
Shell Spirax S5 75W-90.

What does the manufacturer advise?

Transmission fluids 75W-80 and engine fluids 15W40 (10W40) are well suited. TM-4-12 (80W-85) recommended by the automaker is generally an excellent option if you find the original.

Suitable oils

In 1996, a special Rexol T oil was developed for VAZ 2115 transmissions with the following parameters: 80W-85 API GL-4. Two years later, another oil received approval - Lukoil TM-4 with parameters SAE 80W-85. According to viscosity characteristics, the permissible range of use for different oils is:

75W-80 – from -40 to +25°С
80W-85 – from -30 to +35°С
80W-90 – from -30 to +45°С

Step-by-step instructions for changing the oil in a VAZ

In order to fill the gearbox in a VAZ 2114, you need to prepare the necessary equipment in advance. It is better to pour in places where you don’t mind getting the floor dirty, because some of the liquid runs out during the pouring process. For the VAZ 2114 gearbox you will need a funnel and a long, thin hose, at least fifty centimeters. The gearbox oil must be warm, just like the car itself, so you should warm it up in advance. Then you should drain the oil from the box so as not to mix their components.

We drain it using the same tube and a small suction. It is better to throw out the old oil; it has already served its purpose and is no longer useful.

In the VAZ 2114 box there is a small breather closed with a rubber cap. It needs to be removed, and it is recommended to clean them well. Before pouring lubricating fluid into the VAZ 2115 box, you should check its balance. If you don’t know how to check the oil level in a VAZ gearbox, then everything is simple, take out the dipstick and look at the indicator. However, this does not apply to cars younger than 2003; it is not possible to check the number on them; you should only be guided by the indicators of the kilometer counter.

Next, you need to unscrew the plug and let the oil in the VAZ 2115 box drain completely. After this, calmly fill in the new fluid.

A hose is inserted into the open hole and oil is poured into the VAZ 2115 gearbox using a funnel. Filling takes place in a few minutes and, based on the volume in these boxes, one person can handle the task. Changing the oil in a VAZ 2114 in a box will cost much more if you do it in a showroom.

VAZ oil change

Changing the oil in a VAZ engine

The oil change in the VAZ 2109 engine and other models of domestic cars is carried out approximately every 10,000 kilometers. If you use a car in winter, often start the engine at idle speed, drive short distances on bad roads, the mileage can be safely halved, since the lubricant wears out much faster.

Change of oil	Price, rub
Engine oil (with filter) - replacement	600 rub.
Automatic transmission oil - replacement	1000 - 2500 rub.
Automatic transmission oil - checking the level	100 rub.
Manual transmission oil - replacement	600 rub.
Manual transmission oil - level check	100 rub.

Oil in the axle gearbox - replacement	600 rub.

How to change the oil in a VAZ car?

The procedure for changing the oil in a VAZ 2110 engine is practically no different from such operations in other cars. You just need to completely drain the old lubricant, install a new filter and add fresh oil. To ensure the most effective protection of engine parts from wear, we recommend that you listen to the following tips:

Changing the oil in a VAZ should be done with a hot engine. Perform it immediately after a trip or warm up the engine to a temperature of 80 degrees. The heated lubricant loses its viscosity and is easily drained into the prepared container;
It is advisable to slightly raise the front of the car to allow the lubricant to completely leave the lubrication system. To do this, you can use a jack or specially designed lifts;
When changing the oil in a VAZ 2115 , try to fill in the exact brand of lubricant that was used previously. If you want to change the manufacturer, be sure to clean the engine of residues with a special flushing fluid;
change the oil in a VAZ 2114, use only those fluids that are recommended by the car manufacturer. As a last resort, you can select a lubricant that is similar in composition and characteristics;
After draining the fluid, the oil pump must be replaced. Otherwise, changing the oil in the VAZ 2110 will be completely useless;
Be sure to check the grease level with a dipstick. Its deficiency can lead to ineffective lubrication of engine parts and their overheating. If you add too much oil, it can squeeze out the rubber seals, causing a leak.
