Abstract:
An automatic transmission is disclosed that includes a clutch pressure control module housing having therein: (1) a plurality of solenoid valves, each of the solenoid valves configured to receive an input of the pressurized hydraulic fluid and to provide a variable output pressure of pressurized hydraulic fluid in response to an electric control signal; (2) means for sensing output pressure from each of the solenoid valves of the plurality of solenoid valves; and (3) electronic control means configured to generate electric control signals to one or more of the solenoid valves of the plurality of solenoid valves in response to (i) a clutch pressure command signal or a solenoid pressure command signal, and (ii) a solenoid output pressure signal from the means for sensing output pressure. The solenoid valves provide hydraulic control signals to clutch hydraulic pressure control valves, which in turn provide hydraulic power to clutch actuators.
