WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2002 Lincoln Navigator, 2002 Ford Expedition, 2001 Lincoln Navigator, 2001 Ford RV Cutaway, and 2001 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

Torque Converter Clutch (TCC) solenoid receives a signal from PCM. TCC solenoid controls application and release of torque converter clutch. If solenoid fails in ON position, engine will run rough (shudder) and engine stalls in Drive at idle, low speeds with brake applied, or in manual 2nd gear. If solenoid fails in OFF position, torque converter clutch will not engage. Transmission Control Indicator Light (TCIL) may flash. On gasoline engines, an On/Off TCC is used. On diesel engines, a modulated TCC is used.
