A drive unit for a motor vehicle, having an engine unit and an axle differential arranged on the engine unit, as well as having drive shafts for the vehicle wheels disposed at least partially in the crankcase. The separating plane between the crankcase bottom part and the oil bearing housing of the crankcase acts as the bearing for at least one drive shaft.

A hydraulic control unit is provided which has a housing made of a light metal and connection devices for the connection with hydraulic conduits. In order to reduce the danger of damage to the housing in the area of the connection devices, a plate made of steel for accommodating the connection devices is held on a flange surface of the housing.

A shifting arrangement for a manual transmission having several forward gears and at least one reverse gear has a shift rotor that is rotated to shift the transmission gears. For this purpose, the shift rotor is connected by way of a cable pull with a shift lever. By moving the shift lever forward or backward from a neutral position, the shift rotor is rotated by way of a step-by-step system. In order to ensure a secure shifting of the reverse gear with a clear assignment for the driver and a protection against an unintended shifting, the reverse gear is operated by moving the shift lever in a second channel which is separate from the forward-gear shifting channel. For this purpose, the shift lever is connected by way of a second cable pull with a preselection shaft. By rotating the preselection shaft, coupling elements can be adjusted between the shift forks and the shift rotor irrespective of their shifting position. By means of the locking elements between the shifting shaft and the preselection shaft, a shifting of individual transmission gears is allowed only if a previously defined shifting position existed.
