I jumped in my 92' bronco E40d and put it in reverse, and I felt it ingage but when I hit the gas it felt like the brake was on. It did the same thing in drive. It was binding up some where. So I had my buddy shift through the gears and everything looked good. So he hit the gas pretty hard, and it made a loud snap sound in the tranny, and it broke loose, and drives now. I haven't driven it more that 100ft. because that was a scary sound. Does anyone have any idea what that was, and how much life do I have left? 129,000 miles on it, by the way.
