2-3 Shift Solenoid Valve

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The PCM de-energized the 2-3 shift solenoid valve when the vehicle operating conditions are appropriate for a 3-2 downshift. With the solenoid valve Off, a 2-3 signal fluid exhausts through the 2-3 shift solenoid valve.
