I hate to admit it, but I got my rubicon stuck. The problem was that for a about 45 minutes afterwards it would run real rough in reverse. I think maybe a little bit of water got in the muffler, but why would it only act up in reverse not in any of the other gears? Later on it seemed to clear itself out.

 

I got a 04 rubicon and every now and then it won`t lock right into reverse and putts backing up, I find if you put it netural or drive and then put it back into reverse it acts fine.
