pipes are required. Ensure the pipe is double-flared.
REMOVAL PROCEDURE

loss.
1. Raise and support the vehicle.
2. Position the drain pan.
3. Remove the transaxle oil cooler hoses from the transaxle oil cooler fittings.
4. Remove the transaxle oil cooler fittings from the transaxle.

^
Tighten the transaxle oil cooler fittings to 38 Nm (28 ft. lbs.).

the transaxle.
