One problem related to transmission slip out of gear has been reported for the 1996 Ford Bronco. The most recently reported issues are listed below.
Transmission jumps out of overdrive, afterwards hard shifts in all gears after high rpms. The fix is to stop, cut the engine off and the transmission resets for lack on a better term. When the Bronco is in od and is just crusing, not in a pull, is when the od jumps out. Like any other thing it does not happen all the time.
