General information about manual transmission (Opel Vectra B)

The gearbox is housed in an aluminum alloy housing and is attached to the left end of the engine. It consists of a gearbox, final drive, and differential.

Torque from the engine crankshaft is transmitted through the clutch to the primary shaft of the gearbox, on which the clutch disc is mounted. The front part of the primary shaft is mounted on a roller bearing, and the rear part is mounted on a sealed ball bearing. From the secondary shaft, torque is transmitted to the differential and to the drive shafts.

In neutral, the input shaft and output shaft gears rotate freely and do not transmit torque to the differential.

The gear shift mechanism is operated by a lever located on the floor of the car using a shift rod. The gear shift mechanism moves the corresponding fork, which moves the synchronizer and ensures a rigid connection of the secondary shaft gear with the secondary shaft.
