Torque Converter Clutch Solenoid

WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2002 Mercury Grand Marquis, 2002 Lincoln Town Car, 2002 Ford Crown Victoria, 2001 Mercury Mountaineer, and 2001 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.

The TCC solenoid receives a signal from the PCM. The TCC solenoid controls application, modulation and release of torque converter clutch. If solenoid fails in ON position, engine will run rough (shudder) and stall in Drive at low idle speeds (2nd, 3rd or 4th gear). If solenoid fails in OFF position, torque converter clutch will not engage.
