Torque Converter Clutch Solenoid

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.
