My daughter's 95 grand cherokee with the 4.0 has a problem when the trans. shifts to O/D, it tries to kill the engine. Feels as it is trying to lock up. Can disconnect the O/D with the switch and everything is normal just no O/D. O/D light doesn't flash or come on when it happens. She has been disengaging the O/D before driving and the trans works fine. Any ideas?
Thanks in advance

My 94 Laredo had the same problem 4yrs ago. Two days after the initial problem indication the transmission locked up at 70mph between Linville & Boone. The only salvageable part was the case. The cost of the factory reman unit installed was $3200. You might want to have a good transmission tech check it out.
