WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 GMC Cab & Chassis Sierra, 2009 Chevrolet Silverado, and 2009 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

If the IMS switch has been replaced, inspect the valve body detent spring to be sure it is centered over the detent lever. This prevents the detent spring from hitting the IMS switch.

Control Module References for control solenoid (w/body and TCM) valve assembly or ECM replacement, setup, and programming.
Manual Shift Shaft Position Switch Replacement for IMS replacement.
