Procedure -

1. Install new O-rings on existing fittings or replace the complete fittings if damaged.

2. Generously coat the cooler fitting internal and external Orings with Eaton Fuller silicon lubricant #71206 or equivalent before installing them into the transmission case.

3. Pilot the fitting over the ends of the cooler tube and slide into the threaded fitting bore, until the threads on the fitting contact the threads in the bore. Because of the tight O-ring fit both into the bore and over the end of the tube, you must push the fitting into the borewhile turning to engage the threads. Tighten fittings to 40-50 lb-ft (54-67 Nm).

4. Install the O-ring type cooler hose adapter fittings into the transmission interface fittings. Then adjust the inlet and outlets in the direction they were removed, and tighten the locking nuts on the fittings.

5. Install the cooler hoses to the transmission and open the cooler line shut-off valves, or refill the vehicle cooling system according to the vehicle OEM guidelines.

Replace the transmission drain plug and tighten to 35-50 lbft (47-67 Nm). Refill the transmission to the required lubrication fill level.
