Minimal events lead up to transmission failure. Odd shifting when accelerating occurred the day of the failure and possibly several times overt the tow years, but very infrequently. Failure occurred at 74,000 miles of primarily highway driving with perhaps two reverses a day resulting at most 2,000 reverses for the life of the car. The same day as shifting problems occurred several times on the way home reverse gear would not engage and after several attempts would stay in gear for only a few seconds before going back into neutral. Never would go into reverse again. Failure required replacement of the solenoid shifters and valve bodies. This is the same failure that was a cause for a recall of several previous year's, including 2004.

My wife was driving the Mountaineer and the check transmission light came on and the o/d light started flashing. We took it to the local mechanic and they said we probably needed a new transmission. We then took it to a transmission specialists and they confirmed we needed to rebuild the transmission. They replaced all seals and valves, torque converter, solenoid pack, transfer case, prndl switch, at a cost of $2500. After reading about several transmission complaints for this model year of Mountaineer, I felt I should report this complaint.
