I'm a new member and thought I might explore if others have had this problem and at what mileage and so on. I have 120,000 miles on a '92 XLT 4X4. First the four wheel drive wouldn't engage, and then the trans failed. There wasn't any grinding or anything, it just stopped going forward and wouldn't make thge light "clunk" sound when the trans engages into gear. I think the reverse still worked, but its at a shop now for a rebuild. Does this sound early for a trans failure? It has been well maintained until the last 6 mos. or so, and I do not baby it. Its an auto trans. What's up?
