Manual Valve

WARNING: This page is about a different car, the 2009 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

The manual valve is mechanically controlled through the gear selector lever. The valve directs line pressure from the pressure regulator valve to the pressure switches and also into the PRN, the PRND4 and the PRND43 circuits.
