ISSUE
Some 2002 Explorer/Mountaineer 4-door vehicles built 11/13/2000 through 4/2/2001 equipped with the 5R55W transmission may exhibit a fluid leak at the transmission cooler line-to-transmission case connection. This may be caused by contamination on the cooler tube between the tube nut and flare, contamination on the tube nut threads or improper installation torque.

3. Install the service 0-rings (W702015-S300) as shown in Figure 3.





4. Reinstall the cooler lines into the case and tighten the cooler tube nuts to 30 N.m (22 lb-ft) (Figure 4).

5. Clean all residual fluid from around the cooler line fittings.
