Torque Converter Clutch (TCC) Solenoid
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The Torque Converter Clutch (TCC) solenoid is used in the transaxle control system to control the application, modulation and release of the torque converter clutch.
The TCC control solenoid is installed on the front valve body. Based on engine RPM, throttle opening degree signals and speed sensor signals, it linearly controls clutch hydraulic pressure. Through this, engagement and slip are controlled. As a fail-safe function, if any control solenoid assembly abnormality occurs, the TCM will disable the current to the TCC solenoid.
