2-3 Shift Solenoid (SS) 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 PCM energizes (turns ON) the 2-3 SS valve. The PCM blocks the exhaust of the 2-3 SS valve fluid to create high pressure in the 2-3 SS valve passage. High fluid pressure from the 2-3 SS valve moves the 2-3 shift valve into the upshifted position.
