Automatic Transmission Oil Cooler Fitting Replacement
Removal Procedure
Notice: Allow sufficient clearance around the transaxle oil cooler pipes and around the hoses to prevent damage or wear which may cause fluid loss.
1. Raise and support the vehicle. Refer to Vehicle Lifting.
2. Position the drain pan.
3. Remove the transaxle oil cooler hoses from the transaxle oil cooler fittings. Refer to Automatic Transmission Oil Cooler Hose Replacement.
4. Remove the transaxle oil cooler fittings (28, 29) from the transaxle.
Installation Procedure
1. Apply sealant GM P/N 12345382 or equivalent to transaxle oil cooler fittings.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners
requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use
paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint
clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid
damage to parts and systems.
Important: The correct thread engagement is critical. The cross-threaded fittings can achieve proper tightness and still leak.
2. Install the transaxle oil cooler fittings (28, 29) to the transaxle.
Tighten the fittings to 38 Nm (28 ft. lbs.).
3. Install the transaxle oil cooler hoses to the transaxle oil cooler fittings. Refer to Automatic Transmission Oil Cooler Hose Replacement.
