Abstract

The invention relates to a gearbox control system for the fluidic operation of a gearbox which includes a plurality of gears that can be selected and shifted by a gearbox actuator device, and for the fluidic operation of two partial clutches of a dual clutch. The invention is characterized in that the gearbox control system includes two reversing pump actuators which are each assigned one of the partial clutches and which each have two connections to which a fluidic AND valve is connected, the latter having a tank connection as a third connection, wherein the gearbox actuator device is connected to the two reversing pump actuators via a fluidic OR valve.
