Automatic Transmission Oil Cooler Pipes Replacement





Use only double-wrapped and use only brazed steel pipe meeting the GM specification 123M or equivalent if replacement of the transaxle oil cooler pipes is required. Ensure the pipe is double-flared.

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 pipes.
4. Remove the transaxle oil cooler pipe fittings at the radiator.
5. Remove the transaxle oil cooler pipes.

Installation Procedure

2. Install the transaxle oil cooler pipe fittings at the radiator.
3. Install the transaxle oil cooler hoses to the pipes.
