Circuit / System Description
The torque converter clutch?(TCC) pressure control solenoid is part of the control solenoid (w/body and TCM) valve assembly which has no serviceable parts. The normally low TCC PC solenoid regulates oil pressure to the TCC regulator valve and TCC control valve. Increasing TCC PC solenoid oil pressure increases oil pressure to the torque converter to apply the clutch. The TCM varies the current to the TCC PC solenoid through a low side driver. Increasing current to the TCC PC solenoid increase oil pressure by closing OFF the solenoid exhaust port. Decreasing current to the TCC PC solenoid decreases oil pressure by opening up the solenoid exhaust port. The TCC PC solenoid 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.
