Diagnostic Aids

WARNING: This page is about a different car, the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Cadillac Escalade EXT, 2007 Cadillac Escalade ESV, and 2007 Cadillac Escalade. 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.
