Installation of a short-stroke rocker on a VAZ 2109. Automatic transmission on a VAZ 2109

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.

More about installation

Now our domestic, beloved and famous car “VAZ-2112” has joined the models with an automatic transmission, which is quite natural. However, it is not yet possible to replace the gearbox with an automatic transmission yourself:

• Quite a few experiments were carried out and with the technical support of the ZF concern (a German concern) it was possible to release such a modified model of the usual “twelfth”
• It is important to note that a not quite real full-weight automatic VAZ 2112 gearbox was installed in our old VAZ, but instead a variator of V-belt equipment was used (new development)
• This happened as a result of the fact that a regular two-liter engine simply does not fit the car, due to the lack of technical modification capabilities and their directions

Let's try to figure out together how the installation of the VAZ 2112 system with an automatic transmission takes place:

• Firstly, a power unit was installed, located transversely, otherwise it would not fit
• In addition, the entire hydraulic mechanics system was rebuilt, due to the fact that it is very expensive to maintain and repair.
• Finally, the last stage is the development of the machine’s power; it is important to understand that uncontrolled (uncontrollable) power may well lead to completely unexpected situations, even emergency ones, especially when the vehicle is moving
• It is also important to note that the clutch pedal, which was in the manual transmission, is no longer needed here.
• Therefore, using the developed stand, it was possible to hide it
• The result we get is this: the torque variator is 145 Nm, and now it can work at 130 Nm
• It turned out during the experiments that the hydromechanical gearbox is completely unsuitable for the “tenth model” - since the transversely mounted engine requires a very compact transmission
• Therefore, from the ZF range we had to select a stepless variator model VT1 with hydraulic control
• For your information, similar electronically controlled units are used on Mini cars (having only two front seats and a trunk)

Disadvantages, breakdowns and problems of the Lada Samara box

The reliability of the manual transmission is weak, the transmission is famous for unclear shifts and howling

Gears switch off spontaneously due to wear of the locks on the couplings and gears

The box hums most often due to a lack of lubrication or when the bearings are damaged.

A strong crunch when switching hints at a quick replacement of synchronizers

The weak point of the gearbox is the rocker; it often requires repair or replacement

Another common problem is oil leaks from different seals.

Which cars are replaced with automatic transmission?

The manual transmission on the automatic transmission is replaced on those cars that were equipped with both types of switching mechanisms at the factory. For example, if you want to equip a VAZ 2109 with an automatic transmission, you will have to search for a suitable box for years, and this is unlikely to bring success. But Toyota or Volkswagen almost always have paired models with automatic transmissions. There are a number of successful projects of this type with these models:

1. Mitsuibishi Pajero. The SUV provides a lot of space under the hood to install any equipment you want and get excellent performance. Moreover, the engine can easily withstand any load.
2. Toyota Land Cruiser. Older models came with a manual transmission, but here the replacement will be difficult due to all-wheel drive systems. Therefore, the work should be entrusted to professionals with good experience.
3. Opel Vectra. At the same time, there are alterations both on older versions of the B series and on more modern C. The machines last a long time even with a makeshift installation, delighting with their characteristics.
4. Mazda 3. They also often change the manual to an automatic on the Mazda CX-7, which works great with an automatic transmission. Engines from Japanese concerns serve better under automatic transmissions.
5. BMW of various models. Bavarians today practically do not offer manual transmissions, but before there were plenty of them. There are even a number of service stations that re-equip such cars, including replacing the transmission.

As you can see, the list contains many popular models of cars. This means that even on less popular vehicles, replacing a manual transmission with an automatic one that is easy to use is quite possible. You just need to find out an individual approach to each machine, since there cannot be any factory instructions in this regard. On older cars, the procedure is much simpler, because they don’t have a lot of electronics that block the work with any changes.

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.

Tuning the VAZ 2109 transmission

The classic transmission of all VAZs is manual. It is quite reliable, cheap to maintain and well suited for use on domestic roads.

Upgraded car

There are several popular types of tuning for manual transmissions. They appeared as a banal need to improve the performance of the car. The main work packages include:

• Replacing the backstage.
• Conversion from 4-speed to 5-speed.
• Installation of a sports row.
• Modernization of the pedal unit.
• Replacement of the main pair and differential.

Types of box configuration

The configuration of gears can be different, depending on what you want to get as a result:

Useful tips

It is extremely important to monitor the serviceability of the gearbox, and if signs of breakdown are detected, fix them immediately. Do it yourself or with the help of a car service - this is your personal decision.

When operating a car in city conditions, you have to change gears more often. Therefore, it is recommended to use motor oil here. This ensures that the synchronizers remain effective longer. Transmission oil is better suited for highways, increasing the life of bearings and gears, although the synchronizer lasts less.

Work on dismantling the five-speed gearbox VAZ 2107

Installing the car on a lift (you can use an overpass or a pit) is preceded by disconnecting the battery and removing the radio panel:

1. Remove and disassemble the gearbox rod.
2. Remove the cover from the gap where the lever attaches and remove the foam filling.
3. Remove the exhaust pipe from the exhaust system.
4. Move the starter, disconnect the speedometer wire.
5. Unscrew the bolts holding the cardan and remove it.
6. The clutch cylinder is removed using the same method.
7. After this, the gearbox is removed from the car. To do this, it is best to invite assistants who will support the mechanism while you unscrew the mounting bolts. At this stage, it is also advisable to drain the transmission oil.
