I bought the Explorer Limited and have been satisfied with it except for the transmission. During the warranty phase (5 yr/50K mile) Ford repaired the transmission but at 87K the trans had to be rebuilt. Again at 103K the trans was repaired by Ford Dealership (this time Ford paid) and they claim the fix it part as recommended by Ford Detroit was installed. I have lost confidence in my Explorer. Has someone had similar experiences w/ their transmission and will this fix it be good for another 80-100K miles?
