Abstract: A control system for a double clutch of a power-shiftable motor vehicle transmission, in which both clutches are hydraulically actuated by an electro-hydraulic control system which is controlled by an electronic control apparatus according to a predetermined program responding to the signals of a speed selector lever. For starting, the control system is adapted to be additionally manually influenceable by a clutch pedal which acts by way of a hydraulic transmitter cylinder and a receiver cylinder on the control slide valve member of the control system.
