ABSTRACT:
In a hydraulic control system of an automatic power transmission is provided a line pressure control device which is operative to supply the pressure regulator valve of the control system a fluid pressure equal to the throttle pressure when the throttle pressure is lower than a predetermined value and a fluid pressure maintained at the predetermined value when the throttle pressure is higher than such a value or under conditions in which the transmission mechanism is in a forward drive gear condition in which engine braking can be effected in a vehicle.
