Torque Converter Clutch (TCC) Releases

WARNING: This page is about a different variant/trim than selected.

Torque Converter Clutch (TCC) Pressure Control (PC) Solenoid 

If the TCC is applied when an electrical condition commands a protection mode, the TCC PC solenoid defaults to its normally-low state (OFF), allowing PCS TCC fluid to exhaust and the TCC to release. See Drive Range - Sixth Gear for a complete description of TCC release.
