When designing the VAZ-2105, the designers slightly redesigned the gearbox, changing the gear ratios of each gear. But in general, the design of the gearbox of this car was not very different from previous modifications.
The first gearboxes were four-speed, three-shaft, with constant mesh gears and synchronizers in all forward gears. Later this box was modified by adding an additional 5th speed. Moreover, the 4-speed modification was taken as the basis for its creation, so the five-speed direct transmission remained in 4th speed.
Subsequently, the gearbox developed for the VAZ-2105 became the main one and was equipped with all cars of the classic family until their production ended. In the future, we will consider the maintenance of a 5-speed gearbox, since the repair of a 4-speed VAZ-2105 gearbox is done basically in the same way as a five-speed gearbox, due to the fact that the design of these versions of the gearbox is largely similar, then maintenance and repair operations - identical. We will also find out how to convert a 4-speed modification into a five-speed one.
The main advantage of such a gearbox was the high reliability of the unit and unpretentiousness in operation, so repair of the VAZ-2105 gearbox is not required very often; it is capable of working out a significant service life without any special intervention and with minimal maintenance. Another positive quality is the maintainability and availability of spare parts and repair kits, so repair of the 2105 gearbox can be performed even in a garage with a basic set of tools.
Gearbox service
But first you should consider the maintenance that needs to be carried out on this unit. There is only one thing - checking the level of lubricant and, if necessary, topping it up to the required level.
A manual transmission itself is not demanding, so the lubricant used in it performs only one function - it lubricates the component parts of the unit. Therefore, the oil in the box should be changed every 60 thousand kilometers.
Before servicing the gearbox, you should know what kind of oil to pour into the VAZ-2105 gearbox. The transmission of this car requires gear oil with an API quality level of GL-5 or higher and a viscosity of 75W-90 or 85W-90 according to the SAE classification. The oil volume in the gearbox is 1.35 liters.
Checking the oil in the box is not difficult, but to do this, the car should be placed on an inspection hole or overpass.
And then the actions are as follows:
- On the left side of the gearbox housing (in the direction of travel of the car) we find the control filler plug (located just above the bottom cover of the box);
- Use a rag to remove dirt around the plug;
- Using a wrench of the required size, unscrew the plug;
- You can find out the level using a small mirror and a flashlight, a screwdriver or even your finger, in general, whatever is convenient. The lubricant level is considered normal if the oil reaches the bottom edge of the hole;
- If the oil level is below the level, use a technical syringe to bring it up to normal (as soon as the oil begins to flow out of the hole, tighten the plug);
Checking and adding lubricant to the gearbox should be “cold”. If maintenance is carried out immediately after a trip, it is necessary to allow time (10-15 minutes) for the oil to completely drain, otherwise the level will be incorrect when checking.
If the time has come to change the oil, then first drain the used lubricant - clean the bottom cover of dirt, place a plastic container and unscrew the drain plug.
Then wait until the oil has completely drained and tighten the plug.
And then everything is done in the same way as when checking and replenishing the level, only you will have to pump the required amount of oil into the box with a syringe.
After replacement, you should not immediately dispose of the waste; before doing so, it is better to check it. To do this, take a magnet, tie a thread and lower it into a container with old oil. Next, you should move the magnet along the bottom. Then we take it out and examine it. If a large amount of metal shavings is found on the magnet, this may indicate the appearance of intense wear, and in this case, overhauling the gearbox and troubleshooting the components will not be superfluous, since it will allow identifying and eliminating the malfunction at an early stage.
Replacing a manual transmission with a used VAZ 2105, 2106, 2106
A rational solution is to replace the damaged box with a serviceable one, even if it has been used. The range of offers of this type is extremely wide. Often, replacement services are offered by private craftsmen. buy a used gearbox for a VAZ 2104, 2107 5-mortar from them . Should you trust such specialists? If the person is one of your own, proven, then, of course, there is no reason to worry. If you are looking for a specialist for the first time, it is more rational to give preference to specialized workshops rather than private owners.
Replacing the box at a service station is carried out quickly, with a guarantee of quality. Moreover, both the unit itself and the car mechanic work performed are at a decent level. As for the cost of replacement, cooperation with private owners is not always cheaper. The workshop's services benefit from the long-term, maintenance-free operation of the replaced transmission unit.
Box repair: can you do it yourself?
Repairing the five-speed gearbox of a VAZ 2107 and other models is technically quite complex. Especially if it cannot be done without dismantling or rebuilding the transmission unit. If you do not have special knowledge, experience in car mechanics, or special tools, it is better not to experiment with independent work. Eliminating the consequences of incompetent repairs can be quite expensive. Overpayments are not only possible, but also very likely.
Professional repair of the classic VAZ 2105, 2106 (5-mortar) gearbox will reduce financial risks. The service can be ordered in our workshop on the most favorable terms. We repair boxes of all models of Zhiguli, we guarantee efficiency and quality of work performed.

Several features of repairing a VAZ five-speed gearbox
Professional repair of a VAZ 5-speed gearbox , like any other auto mechanic procedure, has its own characteristics. They are determined, first of all, by the specificity and complexity of the faults. Their number also plays a role. There are often cases when it is more rational to buy a used gearbox to replace the original unit than to bother with repairs.
If you want to restore a transmission unit, it would be a good idea to understand the specifics of providing transmission repair services.
What is bulkheading and how is it done?
Repair of the VAZ 2105, 2107 and other models gearboxes can be routine or major. The latter involves a complete overhaul of the unit. Professional specialists always conduct detailed diagnostics of the transmission unit before overhaul. The data obtained allow us to get a clear idea of the physical and technical properties of the elements of the unit.
A major overhaul of a VAZ 2107 manual transmission may have different costs, and the same applies to the restoration of gearboxes of other models. The price is determined by the complexity of the work performed, the quantity, and the specifics of the faults.
Bulkheading requires compliance with certain regulations. When performing work, our workshop specialists strictly follow the technical repair diagrams. The station is equipped with a special unit for carrying out routine maintenance. The availability of specialized equipment and the competence of the personnel make it possible to guarantee that the overhaul is performed in accordance with the technical recommendations of the gearbox manufacturer.
A few nuances of current repairs
If there is a problem with the transmission unit, do not rush to decide to replace it. to buy a used VAZ 2107 5st gearbox . We recommend that you first contact a workshop to diagnose the unit and identify the causes of malfunctions in the box. It is quite possible that the damage will not be so serious and a simple repair will be enough.
Repair work is carried out, as in the case of overhauling the transmission unit, in strict accordance with technical regulations. Worn parts are replaced with new ones. Restored elements are brought back into working condition. The correct operation of the unit as a whole is checked.
When is maintenance necessary? You should contact a workshop if you notice deviations in the operation of the transmission unit that do not radically affect safety or driving comfort. Moreover, there is no point in delaying repairs. The longer a gearbox with defects operates under standard (and even more so under extreme) conditions, the higher the risk of worsening problems and, accordingly, increasing the cost of restoration work.
How do specialists work?
Our workshop uses a proven, effective scheme of cooperation with clients within the framework of major and current repairs of transmission units. The same applies to the replacement of units and the sale of spare parts. If you need a used VAZ-5 box, you can buy it at the best price and without intermediaries from us.
As for repairs, we use the following scheme:
- receiving a client, conducting diagnostics;
- discussion of problems with the unit, construction of a repair scheme, calculation of estimates;
- approval of the estimate by the client;
- carrying out repair work.
The estimated cost is most often fixed. In some cases, it is possible to change the repair price if additional defects are identified. But the amount is always agreed with the client.

Common faults
Now let's go over the main malfunctions that can occur with the gearbox. There are not many of them, but most of them are eliminated using the transmission removed from the car.
So, the main malfunctions of the VAZ-2105 gearbox are:
- Increased noise when the gearbox is operating (at a certain speed or at all);
- Difficulty switching to another speed;
- Unclear switching, speed loss;
- Lubricant leaks;
In turn, each malfunction can have several causes.
Noise Removal
The noise of the VAZ-2105 gearbox can occur due to wear of bearings, wear of gear teeth and gears, as well as synchronizers, and axial displacement of the shafts relative to each other.
If such a problem occurs, it will be necessary to remove the transmission from the car, since it cannot be repaired otherwise. Note that eliminating noise is one of the most difficult operations to perform, since it requires complete disassembly and reassembly of the gearbox with replacement of worn elements.
In addition to the standard set of keys and screwdrivers, you will additionally need a universal puller. Next, we’ll look at how to completely disassemble a VAZ-2105 5-speed gearbox.
So, all work is done on the removed gearbox:
- Drain the oil and remove the bottom cover. We immediately assess the condition of the gear teeth. If their damage is not noticeable, most likely the noise is coming from the bearings;
- We check the position of the gearshift lever (it should be in neutral), after which we dismantle the gear shift mechanism (link) from the gearbox;
- Remove the cover of the clamps and remove the springs and balls;
- We remove the elastic coupling from the secondary shaft, and then its hub (to unscrew the hub nut, unscrew the bolt securing the 3rd and 4th gear forks, engage 1st gear in the gearbox and displace the 4th gear synchronizer clutch. Two at a time the gears are engaged, the gearbox will be blocked and the nut can be unscrewed);
- We unscrew the speedometer drive, the sensor for turning on the reverse speed light and the exhaust system pipe mounting bracket;
- We unscrew the fastening elements of the rear gearbox cover (5-speed gearboxes have 5 external nuts and 1 internal nut, 4-speed gearboxes do not have an internal nut). Then remove the cover. In this case, the bearings are second. the shaft and the 5th gear block will be disassembled - the inner races will remain on the shafts, and the outer ones, together with the rolling elements, will be in the cover, and all this will need to be dismantled for replacement;
- Remove the speedometer drive gear and oil deflector from the secondary shaft;
- We dismantle the gear block of the 5th and reverse gears by unscrewing its fastening bolt installed in the shaft, as well as the reverse intermediate gear from the axle;
- Remove the 5th gear synchronizer from 2nd. shaft, the 5th and reverse gear shift fork together with the axle, then remove the 3rd and 4th gear axle block;
- We dismantle the synchronizer hub and the reverse gear from the second. shaft;
- We unscrew the bolts securing the pressure plate of the secondary shaft bearing and remove it;
- Unscrew the clutch housing from the gearbox;
- Unscrew the intermediate shaft bolt and remove the front bearing;
- We remove the rear bearing of the intermediate shaft, after which it can be pulled out of the box body;
- We remove the axles and forks of the remaining gears, as well as the axle block of the 1st and 2nd gears;
- We take out the input shaft;
- We remove the secondary shaft along with the gears;
Well, then troubleshooting of the component elements is carried out, worn and damaged components are replaced and assembly is carried out.
Note that this disassembly diagram is general and does not consider such nuances as removing retaining rings, sealing washers, engravers and other small elements.

Difficulty switching
Now let's briefly look at other faults. Difficulty shifting gears will be next.
The reason for this may be:
- Wear of the switching mechanism or its deformation (scenes);
- Wear, the appearance of burrs on the gear shift axles or on their seats, jamming of the crackers;
- Damage or wear of the splines of the synchronizer sliding couplings;
- Damage and bent shift forks;
In the first case, to restore functionality, you don’t even need to remove the transmission from the car, since replacing the VAZ-2105 gearbox shifter is possible without dismantling the transmission unit.
To do this, it is enough to remove the lever, boot, and plastic protective cover to provide access to the fastening elements of the switching mechanism, which must be unscrewed in order to remove the mechanism assembly. And then it is replaced or repaired.
Important! In a 4-speed gearbox, a tension spring is attached to the rod from inside the crankcase, which ensures a constant position of the lever opposite 3-4 gears and prevents its vibration. Therefore, when removing the mechanism, you should first lift it a little, and then pry the spring with a hook made of steel wire, remove it from the eye of the rod and hold it in a slightly tense position so that it does not fall into the crankcase. Before installing the new link, use the same hook to hook the spring and install everything in place.
As for other breakdowns that make it difficult to engage the gears, you will have to remove the gearbox, disassemble it, identify the worn or damaged element and replace it.
What to do if the VAZ gearbox starts to malfunction?
For VAZ 2101, 2106, 2107 repairs and gearbox overhaul are in demand services. And the point is not that the specified transmission unit is unreliable and/or short-lived. The extreme operating conditions of vehicles of these models are to blame for many failures of transmission components. It is also impossible to deny the influence of the human (user) factor.
Price range for box repairs:
- Repair of gearbox VAZ 2107, 2106, 2105, 2104 - 2000 rubles.
- Remove the box and put it on - 2000 rubles. (1000 for exchange or repair)
- Exchange of manual transmission 2107, 2106, 2105, 2104 - 5000 (if the body is intact)
- Repair with our spare parts and installation - 4000 rubles (if the body is intact)
- Buy a Zhiguli gearbox - 6,000 rubles.
If you have problems with the transmission unit, you can buy a box for a VAZ 2107, the price of which is reasonable (thanks to the domestic auto industry!). The same applies to the cost of units for other Zhiguli cars. But in this case, the costs of restoring the vehicle’s performance will be maximum. How to reduce them? We recommend several effective methods.
Replacing a VAZ 2107 gearbox and other models
This method benefits from efficiency, cost and quality of results. If you need to restore your car quickly, replacing the transmission is what you need. As for saving money, it is worth considering the possibility of replacing the transmission unit with a used one. It is better to entrust the selection of the unit to qualified specialists. This will minimize the risk of obtaining a transmission unit that is not of the best quality.
Replacement is also relevant if it is necessary to modernize Zhiguli. Do you want to install a five-speed unit on your car instead of a classic? Are you looking for the best offer for the request “ VAZ 4-mortar box (remove) and installation of 5-mortar ”? Our workshop is at your service.
You can replace the classic four with a five-speed one either new or used. By contacting our workshop, you will receive a guarantee directly on the unit itself and all car mechanic work performed.
Box repair
Repair is another way to restore the functionality of the transmission unit. It can be as effective as replacement, but traditionally takes longer. Especially if you have to capitalize on a VAZ 2106 , 2107 or other model. Overhaul requires an integrated approach. It is carried out with the obligatory dismantling of the transmission unit and includes a bulkhead.
Diagnosis of a VAZ gearbox always precedes repair. Moreover, diagnostic methods are used even if the car owner discovers minor defects in the operation of the gearbox. Diagnostics allows you to identify current problems and hidden faults, which can subsequently lead to a complete failure of the transmission unit. It’s not hard to imagine what this could mean on the road.
How much does it cost to repair a five-speed gearbox for a seven , six, and other models? The price of repairs is determined by the number, complexity of actual faults, and the presence of hidden defects. The more there are, the more expensive it will cost to restore the transmission unit. The speed of repair is also determined by the complexity of the work performed.
How not to spend more?
Any repair is an inevitable expense. Many car owners are interested in reducing them. But in the case of VAZ repairs, it is rational to talk not so much about savings as such, but about optimization. It is not enough to reduce the so-called primary costs. It is important not to come to the service station for repairs a week/month after the transmission has been restored.
So how can you avoid overpaying? If we are talking about replacing a transmission unit, the VAZ 2104, 2106, 2107 (5-speed) gearbox, the price of which is affordable, must be purchased from a trusted supplier. Unit repairs should be entrusted to experienced specialists.
Do you want to optimize the cost of restoring a transmission? We have great offers!
Speed "knocks out"
Fuzzy switching on or knocking out the speed occurs due to:
- Wear of the retainer holes in the axle, damage to its springs;
- Wear of synchronizer blocking rings, damage to its springs or wear of teeth;
In this case, it will not be possible to eliminate the malfunction without removing the gearbox. But, it is not always necessary to completely disassemble it. For example, if the 4th gear slips out, you should immediately check the condition of the spring and the lock of the axis of this speed. It is by checking the fasteners that the search should begin. And then, by disassembling the box, we identify the true cause and eliminate it.
Oil leaks
The last common cause is a lubricant leak. This can happen through loosely screwed plugs or a damaged bottom cover gasket. But most often it is the input shaft seal that leaks.
In the first case, the problem can be eliminated simply by pulling the plugs or replacing the gasket. And for this you do not need to dismantle the gearbox from the car. But in the case of a leak in the input shaft oil seal, you will have to remove the box, but you won’t need to disassemble it to replace the damaged rubber element as a whole.
Replacing the gearbox oil seal, if it concerns the input shaft, is not difficult. It is located in the clutch housing, but from the inside, that is, it will have to be disconnected from the gearbox housing. And then the damaged oil seal is removed and a new one is installed.
Then everything is put back together. In case of damage to other seals, the gearbox is disassembled and the damaged element is replaced.
From 4-speed to 5-speed
Finally, let’s consider such an issue as converting the gearbox from 4 to 5 stages of the VAZ-2105. Such a modification is quite possible, since when the five-speed gearbox was created, the basis for it was the 4-speed version. But in this case, you will have to replace some of the components taken from the 5-speed gearbox, namely:
- Back cover;
- Intermediate shaft (with a hole for mounting the 5th gear gear block);
- Secondary shaft (in the 5-speed version it is slightly shorter);
- 5th speed gear block;
- Reverse idler gear axis;
- A set of rods together with a fork for 5th and reverse gears;
- Gear shift mechanism (slide);
- Reverse light sensor;
- Power unit mounting bracket;
Next, it is enough to completely disassemble the 4-speed gearbox and assemble it as a 5-speed gearbox using the specified components.
Types and differences of the VAZ Classic 4-speed gearbox from Vasily Batkovich's Alien
from 1993 - a gearbox was installed with gear ratios I - 3.830; II - 1.971; III - 1.321; IV - 1,000; V - 0.806.
The whole sadness of the situation is in the fact that it is difficult to get a new Pole, that they have saved what to eat and do not walk for a long time, they are starting to leak like bitches. And what’s most unfortunate is that you can’t find spare parts from them in a day’s time. And the Poles, however, are designed for engines with a displacement of 1.7 to 2.0 (there were such ones on Polonaises). Therefore, they practically do not fit the classics; they are installed (by cutting out a piece of the transmission tunnel), then they do not last long and the driving properties are improved purely personally.
Now I’ll move on to my own standard: the gearbox was purchased in September 2011, and in this case it was installed on the car. Gearbox model VAZ-21074-1700010-23. Five-speed ( gear ratios
see above) 5th gear What does the index 23 mean at the bottom (in the photo it is marked with a blue marker on the body): It is deciphered as follows: 20 - box for the main pair 4.1 03 - modification of the insides of the box.
