U1 Shift 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.

345 enable (50) fluid is routed to the U1 shift valve and applies the valve against spring force, allowing PN12345 (47) fluid to pass through the valve into the servo feed (44) fluid circuit.
