WARNING: This page is about a different car, the 2004 Pontiac Sunfire, 2004 Chevrolet Classic, and 2004 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
Release fluid pressure is routed to the torque converter in order to keep the TCC released. Fluid leaves the converter in the apply fluid circuit.
