ABSTRACT:
A control system for a transmission comprising a primary pulley having a hydraulically shiftable disc, a secondary pulley having a hydraulically shiftable disc, a belt engaged with both pulleys, and a hydraulic circuit having a pump for supplying oil. A transmission ratio control valve is responsive to engine speed for controlling the oil and for shifting the disc of the primary pulley to change the transmission ratio, and a pressure regulator valve is responsive to the transmission ratio for increasing line pressure in the hydraulic circuit with increase of the transmission ratio. A throttle position sensor produces a signal in dependency on the opening degree of a throttle valve of the engine. A solenoid operated valve is responsive to the signal for operating the pressure regulator valve so as to increase the line pressure with an increase of the opening degree of the throttle valve.
