Lock Up Relay Valve

WARNING: This page is about a different car, the 2009 Pontiac Torrent and 2009 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.

1-2 reverse clutch (39) fluid is also routed to the lock up relay valve. Here it assists converter feed (3) fluid pressure and spring force to hold the valve in the released position, thus preventing torque converter clutch apply.
