Abstract
A motor vehicle drive train including a hydrodynamic retarder () that comprises a revolving bladed impeller () and a stationary or counter-rotating bladed turbine () which jointly form a working chamber () that can be filled with a working medium to switch on the retarder () is disclosed. The hydrodynamic retarder () can be mechanically disengaged from the drive train by a disconnect clutch (). A fill level monitoring device () can detect the current fill level of the working medium in the working chamber (), while a disconnect clutch-blocking device () is effectively connected in a communicating or mechanical manner to the fill level monitoring device () and prevents the disconnect clutch () from engaging in accordance with the detected fill level.
