• Q: How to replace the Automatic Transmission Oil Cooler Line on 2001 Chevrolet Lumina?

  A: The first step for replacing an a/t oil cooler hose begins with properly supporting the vehicle and securing enough clearance for transaxle oil cooler pipes and hoses to avoid fluid leakage due to wear or damage. Place a drain pan while removing the transaxle oil cooler hoses from the fittings at the transaxle oil cooler compartment. The next step involves removing transaxle oil cooler clamps from the hoses at both transaxle oil cooler or auxiliary transaxle oil cooler pipes that attach to the Radiator. Afterwards disconnect the hoses from their positions at the Radiator. One should remove the hose clip bolt securing the transaxle oil cooler hose so the hoses become accessible. Install new hoses with a proper thread fit to prevent leaks during installation of the hose clip bolt which should reach 25 nm torque (18 ft. Lbs). After attaching hoses to transaxle oil cooler or auxiliary transaxle oil cooler pipes at the Radiator it is necessary to add the clamps. Secure the transaxle oil cooler fittings through a hose connection process using 23 nm (17 ft. Lbs) torque. Lower the vehicle while avoiding transaxle overfilling because excessive fluid can produce foam that results in shift complaints alongside potential vehicle damage and fluid loss. Verify the fluid level of the system then inspect the repaired areas before searching for fluid leakage.
