Grant's automatic transmission is a classic four-speed six-position automatic transmission (P,R,N,D,1,2) with a torque converter. In addition to the traditional “drive”, the Jatco box is equipped with several more modes - with a fixed first gear and with fixed first and second gears. In addition, there is an overdrive disable button that prevents the box from moving to the highest gear—in this case, fourth—gear. This helps a lot during long highway overtakings. But the developers themselves recommend using modes with fixed gears in conditions of long climbs or off-road conditions.
Automatic transmissions are produced at Jatco facilities in Japan, and on the assembly line of the Tolyatti plant they are only combined with the engine and installed on the car. VAZ dealers will not repair automatic transmissions; they are prohibited from doing so. The service life of the automatic transmission is 10 years. According to the assumptions of VAZ specialists, the “automatic” should easily run up to 150 thousand kilometers, subject to all operating conditions. Within the warranty period of the transmission (and it coincides with the warranty period of the car itself), all problems with the transmission will be solved in only one way - replacement.
All this is good, but sooner or later the chassis will have to be repaired and this is what we will have to face.
Nova Granta with automatic transmission received more than 30 design changes and new components. Let's look at some of them.
A more powerful engine with a displacement of 1.6, 16-valve with a lightweight ShPG, was equipped with a cast crankcase instead of a stamped one, and new mounting points were invented for the sump - directly to the torque converter. This increases the rigidity of the entire structure. The torque converter housing itself was also replaced to fit it into the engine compartment. All this lowered the ground clearance: Granta with automatic transmission has 140 mm ground clearance versus 160 mm for a “manual” sedan. Unfortunately, there is no crankcase protection.
Since the engine-gearbox connection became heavier by 33 kg, the sedan received new, stiffer springs in the front suspension. Externally, they are no different from ordinary 1119, but the markings have a different appearance.
The rear support of the automatic transmission has also undergone changes. It became stiffer and received a more reinforced bracket.
The levers and “crabs” are connected not by the “eighth”, but by their own, more curved stretch.
The outer CV joints are unified with the usual “Granta”, and for the internal joints “tripods” are used, specially selected for the Jatco differential. “Tripods” allow you to achieve a larger operating angle for transmitting torque, and they also have a longer service life than a conventional CV joint. Drive shafts vary in length, so their diameters vary. A rod is used on one side and a pipe on the other. In this way, balance is achieved so that the car does not pull to the side at the moment of sudden addition of traction.
A new, more efficient cooling radiator, which also includes an oil cooler. Now such radiators will be used on all Grants that come with air conditioning.
A vehicle with an automatic transmission is the desire of every lover of the domestic automobile industry. The first cars equipped with automatic transmission were produced in the middle of the 21st century, but until now this technology has not been widely used on VAZ models. But experiments were still carried out.
As far as we know, the “nine” car was not equipped with an automatic transmission, but with a V-belt variator. Thus, the usual stepped hydromechanical automatic transmission is not the best option for domestic vehicles with an engine displacement of less than 2 liters. Causes:
- the transversely located engine makes installing an automatic transmission on the ninth VAZ model quite a difficult task;
- hydromechanics service may not be affordable for everyone;
- insufficient power and torque can cause shifts that are not always intended.
Is it possible to put an automatic transmission on a VAZ 2107?
That’s basically all, you can start assembling and installing the automatic transmission on the VAZ 2107. The only problem will be the mounting cushion for the new gearbox, since it is 7 cm longer than the original one. But both cushions are in the same plane in relation to the body, and special There shouldn't be any structural problems.

There is always a way out
For these reasons, the most suitable option for these engines is a V-belt tensioner. A stacked “pushing” element made of steel allows significant torque to be transmitted between the rollers. The main unit of the V-belt tensioner is two sliding rollers, between which a special belt is tensioned. By moving the halves of the main pulley apart and reducing its working profile, the landing roller while simultaneously compressing it, you can get an enhanced transmission. When the two rollers are in the central position, this is the main gear, and accordingly increasing the profile of the main pulley with lowering the driven one gives an overdrive.
The structure of the design makes it possible, while accelerating, to constantly maintain the motor in operating mode corresponding to the highest power indicator, and the increase in speed occurs through slow, smooth switching of the transmission indicator.
With various manual transmissions, the engine must operate more often in the minimum favorable speed modes; for this reason, a vehicle with a CVT can pick up speed in a shorter time than with a manual transmission.
To prevent wheel engagement on a slippery roadway from causing the car to skid, it is necessary to use a low gear in the manual transmission. In mechanics, everyone knows this process, but in automation it has completely different principles. In the “Drive” mode, the variator perceives a decrease in engine speed, and thus the box automatically switches to a lower gear, so the car is almost unable to brake with the engine, but when switching to another mode, changes appear. Lower rpm equals better braking. In order to switch the joystick from one mode to another when moving, engine braking will start quite slowly and a significant delay will be felt.
Reasons for overhauling and repairing gearboxes
The gearbox in a car (hereinafter referred to as the gearbox) is designed to change and transform due to the influence (switching) of the engine gear ratio. It allows you to change the rate of acceleration, increase speed characteristics at different speeds and makes the wheels rotate at different speeds.
Sometimes every driver, when operating a car, is faced with the issue of servicing or repairing a gearbox on a VAZ 2114. Some began to notice problems in this unit, others are interested in its uninterrupted and long service, since this element is one of the main ones in the overall structure of the car.
VAZ 2114 gearbox device
Types of gearboxes (speeds)
Currently, there are 3 types of gearboxes in cars:
- mechanical, speeds are switched manually using a special lever;
- automatic, in which the gear change occurs without external influence, but only when the gas or brake pedals are pressed. Reverse gear in such cars is activated manually.
- mixed (variable). In this type, the gearbox operates in automatic mode, but under certain conditions it can be briefly switched to manual control.
The most popular because of maintenance, ease of replacing parts and inexpensive repairs is the manual gearbox. It is divided into 3 subtypes: 4-speed, 5-speed and 6-speed. Five speeds for the gearbox are familiar and are the most common.
Features of manual transmission VAZ 2114
On domestic cars, namely the VAZ 2114, the gearbox is manual with 5 speeds. The VAZ 2114 is a very popular model among Russian car enthusiasts, especially among young people, due to its reasonable price and the ability to independently repair almost all components and parts, which reduces the time and financial costs of servicing the car.
It is easier to find and repair any fault in the VAZ 2114 gearbox at the initial stage than to replace it in full with a new spare part in the future.
Before considering the symptoms of breakdowns, you first need to look at what the gearbox on the VAZ 2114 consists of. This will simplify the accurate “diagnosis” of the malfunction. The VAZ 2114 gearbox diagram is located below.
Transmission malfunctions
The main symptoms of a faulty manual gearbox in a car are:
- When switching, the gear is not fixed, but jumps out. The reason is the wear of the fastenings (teeth) of the gears and clutch. It often occurs if switching is done without observing the speed mode. To fix it, you need to replace the damaged parts. Spontaneous gear shifting can also be caused by wear, delamination and cracks in the rubber of the rear support. This also requires replacement.
- To change the gear lever, force is required. In this case, this is a weakening of the attachment teeth to the hinge or deformation of the reaction rod, as well as cracks in the plastic parts in the box drive.
- The transmission begins to make noise in neutral gear. This may be a consequence of both low oil level and its quality (viscosity). The same symptom occurs when the upper bearing on the input shaft wears out. To eliminate it, it is necessary to diagnose the gearbox, and also replace or add oil to the gearbox.
- There is a crunching sound when shifting the gear lever. This happens when the synchronizer wears out. If you miss the initial stage, then with further use you will have to change, in addition to the synchronizer, the entire gear block.
- If the transmission is noisy when moving in gear, then there are several possible reasons. The problem may be in both the upper and lower bearings. In addition to noise, the lever may jam, and then you cannot do without diagnosing the gearbox.
- If you hear a knocking noise in a certain gear without and with a load, then the drive gear of that gear is broken. Here you need to repair the VAZ 2114 gearbox yourself.
- When the gear is engaged, a cracking sound is heard, then the synchronizer locking ring is probably worn out or the pinion axis needs to be changed. Requires urgent diagnosis and can be eliminated when the gearbox is overhauled.
- The visible cause of a gearbox malfunction or its imminent breakdown may be an oil leak from under the gearbox. There can be many reasons for this and diagnosis is indispensable.
When establishing the cause, it is necessary to decide whether the VAZ 2114 gearbox can be repaired and how the gearbox is overhauled. In order to go through all the elements of this complex mechanism yourself, you must first carefully remove and remove it from under the hood. A large number of videos and photos on detailed maintenance of the box and its complete disassembly can be found on the World Wide Web on the Internet, but if you do not have the skills of a mechanic, or are not familiar with the structure of all spare parts and do not know their names, then try to fix the problem yourself It's not even worth it. In the future, this can lead to unpredictable consequences and even more expensive repairs or complete replacement.
Diagnostics, repair and replacement
As we can see, it is not easy for a novice driver to even determine the malfunction of a manual gearbox. Repair or refurbishment is even more difficult. And if the fault is not corrected in time, the result can be disastrous - you will need to replace it with a new manual transmission. And then the answer to the question: “How much does a new gearbox cost for a VAZ 2114?” will bring some annoyance, since the cost of the newest spare part in 2015 prices starts from 15,500 rubles, excluding installation. Of course, you can entrust the installation to a neighbor who knows about cars or do it yourself, then the new box will not be covered by the factory warranty. In such cases, it is better to conclude an agreement and use the services of an official dealer.
Repair of VAZ 2114 gearbox
But replacing an old gearbox with a new one is rarely required. Yes, and they bring things like a new gearbox, usually on order and with full prepayment. In other cases, it is easier to repair worn or broken spare parts. It should be noted that it is not easy even for a professional driver to independently diagnose a malfunction without special diagnostic equipment and a lift. How much it costs to repair a gearbox on a VAZ 2114, as well as car diagnostics, will be told to you at any car service center, dealership, or car workshop. The price list depends on the place of residence, the professionalism of the craftsmen, and the contract. But the financial resources spent on finding out the cause will save you time and nerves in troubleshooting.
Some companies involved in the repair of automotive equipment offer, instead of a new gearbox, to install a repaired (restored) gearbox that has been completely rebuilt. You should not refuse this option, because in this case, along with replacing the manual transmission, you will also be offered a guarantee for the installed unit. At the same time, savings from purchasing a new unit can be up to 70%. Reliable companies value their reputation, so they are interested in good recommendations, as well as in further servicing of their equipment.
How to extend the service life of the gearbox on a VAZ 2114?
You can do without involving an auto specialist if you operate (use) the gearbox correctly, since it is designed for a long service life. The owner of a passenger car only needs to monitor the oil level; if it is low, it must be topped up. Sometimes it is worth changing the oil completely. The main parameters for replacement are specified in the technical passport of the vehicle, but it is better to do this every 60-80 thousand km. mileage
The rapid wear of the VAZ 2114 manual transmission components is affected by the driver’s aggressive driving and frequent and abrupt shifting of the gear lever.
As we see, it is quite possible to extend its “life” with your own efforts and attentive attitude to the iron horse, and who, where will serve you and in what ways depends only on the owner.

Super auto VAZ 2114 – review, specifications and reviews
The VAZ 2114 car began to differ in many ways from previously produced models with its unique appearance. It was officially presented in 2001 and began to be produced at the automobile plant for as long as 10 years. During all this time, the super car VAZ 2114 has gone through many changes both in appearance and the interior appearance of the cabin has changed.
Young people choose the domestic auto industry as their first car. This super car can easily be classified as an inexpensive type of vehicle. And that’s just why you shouldn’t expect high performance from him and place high hopes on him. It is well suited for country trips due to the fact that it has quite good ground clearance, allowing it to overcome minor road obstacles.
Car acceleration
Acceleration of the car is accompanied by the monotonous sound of the engine running at the same speed, which causes the feeling of a burnt out clutch. That is why, for some, this causes hostility towards CVTs. But the CVT VAZ is free of this drawback. Up to 3000 rpm, even with the gas pedal fully pressed, the engine spins up almost synchronously with the acceleration. It feels like acceleration occurs in one, smoothly increasing gear. And after overcoming this milestone, a sudden increase in revolutions occurs, which is accompanied by a noticeable increase in acceleration - as if a classic stepped automatic transmission was under the hood and the Kick-down mode was activated. To install the CVT on the VAZ, one of the mounting points of the internal combustion engine had to be moved to the body.
Despite this, vibrations have become noticeably less. If with a “mechanics” the engine skips at the moment of starting, which causes shaking, then with a variator this effect is noticeable to a much lesser extent. The speed is maintained automatically and drops less frequently into the “critical” zone.
CONSTRUCTION FEATURES
Structurally, the gearbox device is divided into 3 main parts: gearbox housing, rear cover and clutch housing. The internals of the device can be divided into two groups - the main pair and the differential with gear ratios.
The main pair, also known as the drive shaft of the gearbox, performs the function of reducing the speed transmitted from the engine to the crankshaft. The VAZ 2114 GP gearbox reduces engine speed by almost four times (gear ratio – 3.7).
Manipulations with the main pair, aimed at changing the gear ratio, allow you to change the length of the gears, which makes it possible to influence the acceleration and maximum speed of the fourteenth. However, it is not recommended to interfere with the operation of the box without proper qualifications - you can do irreparable things.
Interior of super car VAZ 2114
The interior decoration of the super car VAZ 2114 was made of inexpensive but high-quality materials. From the first point of view of the happy owners of such a car, it can be classified as luxury, since it has an on-board computer, heated front seats, power windows and fog lights.
The on-board computer displays complete information about the remaining number of liters of fuel in the gas tank, the exact number of kilometers that can still be driven. The steering wheel can be easily adjusted to suit you for more comfortable driving of the super car. Inside the car dealership, the developers installed a more modern heating system.
Europanel is equipped with 2 liquid crystal displays. On the left side of the instrument panel there is a sensor for determining the engine temperature. With its help, the driver will easily prevent overheating of the internal combustion engine and power unit. This sensor is designed in the form of a scale, followed by a tachometer, it has a round shape.
The central panel inside the cabin is equipped with emergency signs; when the car is functioning properly, it looks like a dark stripe. Due to the updated panel, the internal ventilation of the cabin has improved, while obvious problems with the air supply to the side deflectors have been eliminated. Car seats in super cars are covered with fabric, which over the years begins to become very worn.
Just like any other car, the presented model is equipped with seat belts. In the cabin, an adjustable light was installed on the ceiling to provide full interior illumination. The rear windows are not automatic, but manual. Basically, car owners try to combat extraneous noise in the cabin and use special materials for this. As a result of this improvement, the car greatly increases in weight.
Super car appearance
Despite the new model releases, there are few differences between them in terms of body appearance.
External changes: the front part of the body, the shape of the lenses, the hood, the radiator grille, better quality plastic on the bumper, spoilers, moldings and linings on the hood have changed.
After additional improvements in 2011, the super car received an increased ground clearance of 5 mm.
The weight of the vehicle is 970 kg, the load capacity is 425 kg and the ground clearance is 160 mm.
The VAZ 2114 vehicle has changed in many ways over time and differs from its predecessors in its new interior design and updated appearance.
It is equipped with external mirrors that have a rectangular shape, thanks to them the driver can better control the current situation on the road. The doors on super cars are equipped with special mechanisms for more convenient opening. It is equipped with wheels of 13 radius, which, if necessary, can be easily changed to a larger radius.
Modified headlights are built into the rear of the car; they have 3 types of brake lights, reverse and turn signals. The updated super car currently has a spoiler, it allows you to increase road grip and dynamic data of the car. This is a surprise for any car owner, since this element is installed immediately at the car factory before release.
