Abstract

A clutch and transmission ratio control system in which a main solenoid-operated valve (14) distributes pressurized fluid to a clutch actuator (18) or a ratio selector valve (19) in response to signals from an electronic control means (16). The ratio selector valve (19) in turn distributes pressurized fluid to a plurality of ratio selector actuators (20, 21) which control the movement of a plurality of ratio selector elements (20c, 21c). In a preferred construction both the main solenoid-operated valve (14) and ratio selector valve (19) are landed spool valves.
