Just ran across a new fix and wanted to let people know about it. Many thanks to FordTechMakuloco for publishing it.
If your tranny is having the servo issues so common to this trans, go to:
Ford Lincoln Mercury Explorer Mountaineer Navigator Servo Bore Fix
Check out their solution. I have not had to do this to mine but if the problem re-surfaces (mine started this and I changed the fluid and the problem stopped) it is a better alternative than a full rebuild with the sleeve install. Can be done by almost anyone. If it does re-surface, all you have to do is replace the O-rings on new servo shaft. A much more economical solution.
