Circuit/System Description
The clutch pressure control (PC) solenoid 5 is part of the control solenoid valve assembly which has no serviceable parts. The normally low PC
solenoid 5 regulates and directs oil pressure to the 1-2-3-4 clutch regulator valve and 1-2-3-4 clutch boost valve. Increasing PC solenoid 5 pressure
increases pressure to the 1-2-3-4 clutch. The TCM varies the current to the PC solenoid 5 through a low side driver. Increasing the current to PC
solenoid 5 increases oil pressure by closing OFF the solenoid exhaust port. Decreasing the current to PC solenoid 5 decreases oil pressure by
opening the exhaust port. PC solenoid 5 power is supplied by the TCM through a high side driver (HSD). The HSD protects the circuit and
components from excessive current flow. If excessive current flow is detected, the HSD will turn OFF. When the fault is corrected, the HSD will
reset.
