Transmission Cooler: Removal and Replacement
Auxiliary Cooler
CAUTION: If a leak should occur in the internal radiator mounted transmission oil cooler, engine coolant may become mixed with transmission fluid.
Transmission fluid may also enter engine cooling system. Both cooling system and transmission should be drained and inspected in case of oil cooler
leakage.
REMOVAL
1. Place a drain pan under the oil cooler lines.
2. Disconnect the two transmission lines from the oil cooler by loosening the two worm gear clamps and pulling the rubber hoses off of the oil cooler
tubes. Plug all oil cooler lines to prevent oil leakage.
3. Remove three oil cooler-to-radiator support mounting bolts.
4. Remove the oil cooler and line assembly from the vehicle.
INSTALLATION
1. Install the oil cooler and cooler line assembly to the vehicle.
2. Install three mounting bolts and tighten to 6 Nm (50 inch lbs.) torque.
3. Connect the transmission cooling lines to the oil cooler by pushing the rubber hoses onto the oil cooler tubes. Tighten the worm gear clamps to 2
Nm (18 inch lbs.).
4. Start the engine and check all fittings for leaks.

REPLACING OIL COOLER IN BOTTOM TANK
1. Remove radiator. Refer to Cooling System.
NOTE: The servicing should be performed by a qualified repair facility.
CAUTION: Once the repaired or replacement radiator has been installed, fill the cooling system and inspect for leaks. If the transmission operates
properly after repairing the leak, drain the transmission and torque converter while hot. Remove the transmission oil pan and inspect sludge and/or rust.
Inspect for a dirty or plugged inlet filter. If none of these conditions are found, the transmission may not require reconditioning.
2. Install radiator. Refer to Cooling System.
