A DCT hydraulic power control system has a pump, a high pressure section for providing oil to actuators of the DCT, a low pressure section for providing oil to a lubrication and cooling system of the DCT, and a regulator for directing excess oil from the high pressure section to the lubrication and cooling section. A hydraulic control includes a first directional valve disposed in a main line of the low pressure section between the pump and the lubrication and cooling system, wherein the directional valve is controlled by an ON/OFF valve disposed between a check valve and the directional valve, wherein the check valve is disposed in a branch line of the low pressure section leading to the high pressure section, and wherein a second directional valve connects the second pressure outlet associated to the low pressure section with a suction side of the pump.
