One problem related to transmission stuck in gear has been reported for the 1997 Jeep Wrangler. The most recently reported issues are listed below.
I was exiting the highway and starting to slow for the merge at the end of the ramp. I was in fifth gear and downshifting into fourth, when I found I could no longer shift. The shifter got stuck in neutral. Luckily there was little traffic and the light just after the merge was green or I would no have been able to pull over. I would have been stuck in the middle of the road and possibly would have caused an accident. It could have also happend on the highway with worse possibilities. The Jeep has been used only as a car. No off-roading or towing. The transmission was also maintained as per manufacturer recommendation. I have that documentation if needed.
