Circuit / System Description
The clutch pressure control?(PC) solenoid?4 is integral to the control solenoid (w/body and TCM) valve assembly and has no serviceable parts. The PC solenoid?4 is a normally high-pressure control solenoid which provides fluid pressure to the B-2-6 clutch regulator valve. The TCM controls the solenoid pressure by regulating the exhaust fluid. When the TCM commands the solenoid off, the exhausting fluid is stopped and the B-2-6 pressure is high. When commanded on, the clutch PC solenoid?4 regulates the amount of exhausting transmission fluid. Solenoid power is supplied by the TCM through a high side driver?(HSD). The HSD protects the circuits and components that the TCM powers. Should the circuit overload the driver will shutdown. After the overload is removed the HSD reset.
