Torque Converter Clutch Enable Solenoid Valve
WARNING: This page is about a different car, the 2003 Saturn Vue and 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The Torque Converter Clutch (TCC) enable solenoid valve is a normally closed, 3-port, ON/OFF solenoid that the TCM controls to apply and release the converter clutch. When de-energized, actuator feed limit fluid pressure is blocked from pressurizing the TCC enable signal fluid circuit. Without TCC enable signal fluid pressure at the end of the TCC control valve, spring force holds the valve in the released position.
