B4 Release 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.

4-5 clutch (40) fluid is also routed through orifice #28 to the B4 release valve and shifts the valve against spring force to the applied position.
