A multiple clutch control system for controlling the operation of clutches in a multiple speed transmission of the type wherein the gear ratio of the transmission is operated by engaging one hydraulically operated clutch while simultaneously disengaging another hydraulically operated clutch includes circuitry responsive to the hydraulic pressure applied to the just engaged or on going clutch for preventing the disengagement of the other clutch until the hydraulic pressure applied to the just engaged clutch exceeds a predetermined level indicating that the just engaged clutch has engaged.
