General information about manual transmission (Mazda Capella GC)

The gearbox converts the torque transmitted from the engine in magnitude and direction. This is necessary to ensure optimal speed, high vehicle cross-country ability and engine efficiency, as well as for reversing the vehicle. The gearbox disconnects the engine and transmission when the vehicle is stopped, parked, and when it is coasting with the engine running.

All models with manual transmission are equipped with a 5- or 4-speed gearbox, combined into a single unit with a differential and final drive. Torque from the engine is transmitted through the gearbox and final drive to the differential, which in turn distributes it between the drive shafts. All forward gears are engaged via synchronizers, and the gear shift lever engages the internal shift mechanism via the gear shift rod.

The procedures for removing and repairing the gearbox are described taking into account that the gearbox bearings do not require replacement and the pressed-in elements are installed in their original positions. Installing new bearings or shafts means that the preload shim thickness must be determined, but this requires specialized tools and techniques that are not available to the amateur mechanic.

Therefore, if the gearbox is damaged or worn out as a result of normal use, the best solution may be to install a new or repair unit.
