Circuit/System Description
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The shift solenoid (SS) valve 2 is part of the control solenoid (w/body and TCM) valve assembly. The SS valve 2 is a normally closed (NC) solenoid valve and controls fluid to the clutch select valve 3, located in the upper valve body assembly, and related clutches. During this diagnostic test, intrusive actions are taken by the transmission control module (TCM) to test the SS valve 2 to see if the valve is stuck OFF. When in first gear engine braking, if first gear ratio is not achieved in a predetermined period of time, the TCM commands second gear and if second gear ratio is attained this indicates a stuck OFF SS valve 2 and the DTC will set.
