A reversing transmission shiftable under load in which the reversing clutches (1, 2) are automatically evacuated by the flow of pressure medium through the clutch (1, 2) not subjected to pressure wherein bores (9, 24), which in this shifting state, are connected to the oil reservoir (5) are placed at the highest point of the piston chamber. The shifting clutches (1, 2) are configured as negative clutches. For modulating the pressure during a reverse shift, an accumulator (27, 28) is provided from which pressure medium flows out via orifices (25, 29). For inching a valve (30) is provided via which the closed clutch (1, 2) can be subjected to a pressure whose level can be continuously varied. |
