A new OE EPC solenoid is put on every valve body to help ensure line pressure stability. The remanufactured valve body is tested on state-of-the are equipment, with special attention paid to the pressure regulator valve to ensure smooth and proper action that will provide appropriate line pressure curves during the various shift events. The simulated drive test also ensures that all clutch pressures, torque converter pressure and shift timing match OE performance.
