The transmission will transform the torque transferred from the engine in size and the direction. It is necessary for ensuring optimum speed and passability of the car, and also for the most economic operation of the engine and the movement of the car a backing. Besides, the transmission separates the engine and transmission during a stop and the parking of the car and at its movement on inertia with the working engine.

Details of the transmission are placed in a case which is screwed by bolts on a back part of the engine.

The torque from a bent shaft of the engine through coupling is transferred to a main shaft of the transmission. On primary gear wheels of the forward course and a gear wheel of a backing which are in continuous gearing with gear wheels on secondary to a shaft are established to a shaft. Gear wheels of a secondary shaft freely rotate on a shaft until the mechanism of gear shifting does not include a certain transfer therefore the corresponding gear wheel with a secondary shaft of the transmission is blocked. The gear wheel of a backing is not synchronized.
