ABSTRACT:
A system for controlling pressure in a transmission comprises a transmission control unit, a valve controller that receives a desired pressure as input from the transmission control unit, a valve driver, a valve that regulates an amount of fluid in a transmission clutch, and a pressure transducer that reads a pressure in the transmission clutch and outputs a pressure reading to the valve controller, wherein the valve controller comprises logic for outputting to the valve driver an instruction for controlling the valve, the instruction being formulated using the desired pressure and the pressure reading.
