The transmission will transform a torque transferred from the engine, on size and the direction. It is necessary for ensuring optimum speed and passableness of the car, for the most economic operation of the engine, and also for car movement by a backing. Besides, the transmission separates the engine and transmission during a stop and parking of the car and at its movement by inertia with working engine.
Details of a 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 primary shaft of a transmission. The secondary shaft of a transmission transfers a torque through differential to drive shaft. Inclusion of transfer is carried out by moving of the sliding coupling of the synchronizer therefore the gear wheel of the corresponding transfer rigidly incorporates to transmission shaft.
On a part of cars the automatic transmission is established.
As the transmission, especially automatic, represents the difficult unit, its repair is necessary for making in a specialized workshop with use of the special equipment.
The operations connected with diagnostics, maintenance, transmission adjustment, and also its removal and installation are given in this section.
