Manual transmission (Audi A8 D2)

The gearbox converts the torque transmitted from the engine in magnitude and direction. This is necessary to ensure the optimal speed and cross-country ability of the car, as well as for the most economical operation of the engine and for the car to move in reverse. In addition, the gearbox disconnects the engine and transmission when the car is stopped and parked and when it is moving by inertia with the engine running.

The gearbox components are housed in a crankcase that is bolted to the rear of the engine.

The torque from the engine is transmitted to the drive shaft of the gearbox via the clutch. The driven shaft of the gearbox transmits torque via the differential to the drive shafts. The gear is engaged by moving the sliding clutch of the synchronizer, as a result of which the gear is rigidly connected to the shaft of the gearbox.

The gearbox is a very complex unit and it is recommended to repair it in a specialized workshop, therefore this section only covers the removal and installation of the gearbox.

To remove the gearbox, you need to lift the car and secure it in this position. You also need to use a stationary jack.
