Often during the operation of the car, problems may arise with the operation of certain units. The gearbox on the first and second generation Samaras has never been very reliable, so the situation when reverse gear on a VAZ 2114 does not engage is quite common. This article will help you understand the causes of the malfunction and how to eliminate it.

Repair or replacement
If, during checking the condition of the box, serious damage to its elements was revealed, then serious repairs cannot be avoided.
It should be immediately noted that independent dismantling, repair and reassembly of a gearbox requires not only very good equipment (nominally a pit or overpass, a lifting device, as well as a large set of tools are required), but also very serious knowledge.
That is why, if the gears of a VAZ 2114 do not engage, such repairs should be entrusted to specialists from car service centers.
It should be remembered that independent repair or replacement of the gearbox automatically leads to the loss of all warranty obligations from the manufacturer. For this reason, repairs to a car that is under warranty should be entrusted to branded repair shops.
If we talk about the choice between repair and complete replacement of the unit, then in most cases you should choose the first option. This is due to two reasons. Firstly, the cost of a completely new box exceeds 15 thousand rubles. (moreover, this amount is indicated without taking into account the cost of its installation). In any case, repairs will be much cheaper. And secondly, complete wear of the box (to a state unsuitable for repair) is extremely rare.
The cost of the repair work itself varies from service to service and depends on:
- the size of the locality (and, as a consequence, the presence of competitors);
- type of breakdown;
- the size of the car service (and whether it is official);
- additional clauses in the terms of the contract.
Theory of gearbox operation
At the moment, all modern gearboxes are equipped with synchronizers, which are important elements of the gearbox. The essence of how synchronizers work is that they equalize the operation of the gearbox shafts.
Every driver, when switching from second to first gear, has encountered a situation where some kind of obstacle was felt. What prevents you from engaging first gear while driving. This is the synchronizer.
If you have a fairly new transmission, then when switching from an upshift to a downshift you will not find yourself in such a situation. Switching will be carried out without problems. This manifests itself as the components of the unit are used and worn out.
If you have problems with switching, come to Ankara for diagnostics and repair of transmissions of Mitsubishi, Toyota, Lexus, Land Rover, Jaguar, Infiniti, Mercedes, BMW, Audi and other brands.

Checkpoint disassembled
The best way to prevent breakdowns is to take preventive measures. Unfortunately, even the most careful care is not able to protect the box from the occurrence of certain malfunctions.
Replacement box - new or old?
If the reason why the gears on the VAZ 2114 are poorly engaged is due to very severe wear of the gearbox components, and it turns out that its repair will be more expensive than a complete replacement, then the motorist is faced with a choice - install a new gearbox or give preference to a “restored” one.
The first option is certainly preferable, but the fact is that a new gearbox is not cheap at all (as mentioned above).
The cost of a refurbished one is much less (sometimes such a box costs 70% less than a new one).
A rebuilt gearbox is an excellent option, which is almost in no way inferior in quality to a new gearbox, but at the same time costs much less. The only thing to remember is that such units should only be purchased from trusted companies that professionally restore them and provide a guarantee for their products.
It should also be remembered that if there is a choice, it is better to give preference to the “middle option”. You should absolutely not purchase refurbished boxes from little-known companies at a very low price.
If you have a mechanic
Gears shift poorly in a car with a manual transmission for three reasons. The first of these is a malfunction of the clutch when it does not completely disengage (drive). The first sign of this malfunction is that the reverse gear is engaged with a characteristic crash. The rear one reacts to this anomaly more noticeably than other gears, because it is the only one not equipped with a synchronizer.
The second reason is a defect in the gear selection mechanism of the gearbox. And finally, the third is excessive wear of the gearbox synchronizers.
There are also several clutch malfunctions in which manual transmission gears shift poorly:
- Air in the clutch release hydraulic drive or fluid leakage from it. The malfunction is eliminated by replacing failed components of the hydraulic system and pumping it.
- Worn or broken clutch release fork. The part requires replacement or repair.
- Warping (runout greater than 0.5 mm) or too thick new driven disk.
- Failure of the basket (temperature deformation of the pressure plate or its distortion).
- Loss of mobility of the support bearing of the gearbox input shaft (at the end of the crankshaft to which the flywheel is attached).
- Jamming of the clutch driven disc hub on the splines of the gearbox input shaft. To eliminate the defect, clean the splines of the gearbox hub and input shaft. It wouldn’t hurt to lubricate them a little with lithol.
There is too much free play in the clutch release fork. Its value needs to be clarified with the manufacturer, since it is slightly different for different cars. Until you find out the value of this parameter for your car, set it from 5 to 8 mm. Too little free play of the fork is also undesirable, as it leads to clutch slipping and increased wear of the release bearing.
Excessive wear of synchronizers mainly occurs in those gears that are engaged more often: these are usually first, second and third. The rear one is not included in this list because it does not have a synchronizer. When your gear shifts poorly, and you assume that the reason for this is wear of the synchronizers, firstly, you should only have difficulties with this while driving. Secondly, in this case it switches better if you use double squeeze.
For those who don’t know what double squeeze is. To shift to a higher gear: depress the clutch, engage neutral, release and depress the clutch again, engage the gear.
Backlash in the so-called “helicopter” is one of the reasons for unclear gear shifting
To switch to a lower gear: double squeezing must be combined with re-engaging, that is, when the clutch pedal is released and the gearbox is in neutral, you need to press and release the accelerator pedal. This is how gears are changed in cars that do not have synchronizers. If the gearbox shifts easier using double squeezing, then the culprit for poor gear shifting is most likely worn synchronizers.
If the gears shift poorly when the car is standing still with the engine turned off, the fault may only be in the gear selection mechanism of the gearbox.
Look for damage or check that it is adjusted correctly. Don't even think about the clutch and synchronizers.
Advice for motorists
Above we have already talked about why the reverse gear on the VAZ 2114 does not engage and how to correct this situation. But it should also be noted that proper and timely care of the gearbox will help either completely avoid such a situation or postpone it for as long as possible.
There are only two basic rules for this care:
- Change gears, as well as accelerate and brake the vehicle as smoothly as possible, without jerking.
- Periodically check the oil level, replenish it as it is used, and also replace the entire volume if it is worn out.
These simple rules will help to significantly increase the service life of the entire box and its individual parts.
The reverse gear of the VAZ 2114 stopped engaging - video
Not so long ago, reverse gear began to engage with a crunch, and then disappeared completely! In the video I explained everything briefly and clearly! The same goes for owners of 08/09/10/11/12/13/14/15 models Lada, Kalina, Priora, Grant here too) The reasons were told on the YouTube channel:
Fixing the problem
Let's look at several ways to help fix the problem with engaging reverse gear.
Backstage adjustment
Before you begin solving the problem, take with you everything you might need:
- new gearbox driveshaft;
- speed selector shaft oil seal;
- two ring wrenches 13;
- wrench 10;
- hammer;
- screwdriver.
To fully replace the cardan, you will need to drive into a pit or overpass. In addition, you will need an assistant who will shift the gearbox lever while you adjust it.
Let's start replacing the cardan and adjusting the rocker:
- You need to crawl under the bottom of the 2109 and find your gearbox. Take two 13mm wrenches and loosen the clamp located on the transmission drive rod. After this, you can remove the drive from the gearbox mechanism rod.
- Then take a screwdriver and, with a little force, pull the boot closer to the unit. If you accidentally damage the boot, you can simply dismantle it so that it does not bother you. Now take a 10mm wrench and unscrew the locking screw on the cardan.
- Next, take a hammer and very carefully knock the gearbox driveshaft off the shaft. Do this carefully so as not to damage the shaft. Remove the cardan boot if you did not remove it initially. If necessary, replace the speed selector shaft oil seal.
- At this point we can consider that half the work has already been done. Now you need to install the driveshaft of the box. We install the element in the reverse order. First, install the new boot in place, and then place the cardan on the shaft. Remember that the position of the retaining screw must coincide with the recess on the shaft.
- When the universal joint is in place, tighten the fixing screw and install the boot on the universal joint. You also need to put the gear shift drive rod on the cardan rod, but there is no need to tighten the clamp.
- Next, you will need the help of another person, since you need to adjust the gearshift lever. Ask your assistant to sit in the driver’s seat: he should set the gearshift lever to “neutral” and move it slightly to the right. In this position, an assistant should hold the lever while you tighten the cardan clamp.
When the cardan adjustment is completed, you need to check how the speeds on the lever are switched on. If the problem that caused the reverse gear to not engage in your VAZ 2109 was in the cardan, which is most likely, then after replacing the element the fault should disappear.
Changing gearbox oil
Also, one of the common reasons why reverse gear in a VAZ 2109 does not engage is poor gear oil. As stated above, the liquid has already lost its properties and its further use does not make sense. But how do you understand that the transmission fluid has already exhausted its service life? This issue should be taken seriously, because the fluid replacement procedure is not that cheap. Therefore, you need to know for sure that the gear oil has lost its properties.
Why reverse gear does not engage - common reasons
In this article we will look at the main reasons:
Speed switch
- The first thing you need to pay attention to is the rocker itself and the cardan - it often happens that the rocker slips, the splines are ground off or the clamp is loose. In this case, you will need an overpass or a pit.
- Reverse gear locking mechanism. To check this mechanism, you need to remove the gearshift knob (the dashboard between the seats) and look. Everything will become clear.
- If you checked the first two points and found no problems, then you will have to remove the gearbox.
- The fixing bolt was cut off.
- Fastening the gear selection mechanism.
- A spring (the most common one sometimes bursts).
Alternatively, the reason may be in the release bearing, but then all gears would be engaged barely and with a crunch. You can also try adjusting the clutch pedal.
Extending the service life of gearboxes
You will be able to use your car for many years without going to car repair shops if you can follow basic recommendations. They will extend the service life of the gearbox, minimize possible problems, breakdowns and the need for repair work.
There are only two recommendations.
- Always try to monitor the oil level in the gearbox. If it drops, be sure to top it up immediately, do not delay the procedure until later. When the oil becomes unusable, change it completely, rather than fill in the missing amount.
- Avoid aggressive use, do not jerk the gears sharply, accelerate smoothly, and brake similarly. A simple caring attitude towards the gearbox will allow you to avoid wear and tear and numerous breakdowns.
As you can see, solving problems with checkpoints is not so easy. Therefore, the best option is to prevent their occurrence.
