DTC P2719-P2721
Circuit / System Description
The clutch pressure control?(PC) solenoid?4 is part of the control solenoid (w/body and TCM) valve assembly which has no serviceable parts. The normally low PC solenoid?4 regulates and directs oil pressure to the 2-6 clutch regulator valve. Increasing PC solenoid?4 pressure, increases pressure to the 2-6 clutch regulator valve. The TCM varies the current to the PC solenoid?4 through a low side driver. Increasing the current to PC solenoid?4 increases oil pressure by closing OFF the solenoid exhaust port. Decreasing the current to PC solenoid?4 decreases oil pressure by opening the exhaust port. PC solenoid?4 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.
