A drive unit for a vehicle which includes an engine, transmission and hydrodynamic retarder having a rotor and a stator. A retarder shaft is rotatably supported by two bearings and extends through the housing of the transmission. A sealing element provides a seal between the retarder shaft and the transmission housing for separating the operating medium of the hydrodynamic retarder from either the transmission lubricant or the lubricant for one of the two shaft bearings.
