Repair Procedures
WARNING: This page is about a different car, the 2010 GMC Sierra, 2010 GMC Cab & Chassis Sierra, 2010 Chevrolet Silverado, and 2010 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.
- Control Module References for control solenoid valve assembly or ECM replacement, setup, and programming.
- Manual Shift Shaft Position Switch Replacement for IMS replacement.
NOTE:
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.
