Diagnostic Aids

WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Inspect the ISS, harness, connector, and control solenoid (w/body and TCM) valve assembly pins for metallic debris and the 1-2-3-4 and 3-5-R clutch housing machined teeth surface for damage or misalignment. Proper torque of the OSS mounting bolt is critical to proper OSS operation. Use the J 35616  GM-approved terminal test kit for any test that requires probing the control solenoid (w/body and TCM) valve assembly harness connector or a component harness connector.
