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, for the most economic operation of the engine, and also for 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 bolts fastens to a back part of the engine.
The torque from the engine through coupling is transferred to a main shaft of the transmission. The secondary shaft of the transmission transmits torque through differential to drive shaft. Inclusion of transfer is carried out by movement of the sliding synchronizer coupling therefore the gear wheel of the corresponding transfer rigidly connects to a transmission shaft.
The automatic transmission is installed on parts of cars.
As the transmission, especially automatic, represents the difficult unit, its repair needs to be made in a specialized workshop with use of the special equipment.
The operations connected with diagnostics, maintenance, adjustment of the transmission, and also its removal and installation are given in this section.
