Abstract
A pressure supply to an automatic selector device of a change-speed gearbox, controls working pressure via a multi-path valve device. The working pressure is supplied either only to clutch actuators of two drive clutches located in the force path before the change-speed gearbox or to selector actuators for the actuation of selector clutches producing the force path within the change-speed gearbox. The clutch actuator of one drive clutch is subjected to a load-dependent main pressure in the latter case.
