Re: Transmission reset
The battery is under the front passenger seat. With the seat all the way forward you can easily remove the negative terminal. Doing it while inside the car with the doors closed would be very awkward.
After the threads on removing the battery cable, Jeep did come up with a TSB that included a flash to a control module. If you haven't had that done, have the dealer check if your vehicle should have it done.
If you need a shoulder to cry on ...
... pull over to the side of the road!
