Have been doing a lot of reading on problems with this transmission. sounds like some are popping out of gear. Mine is not but my third and fourth gear are much louder then the rest espicaly when accelerating. I have only 400 miles on it. I am trying to find a dealer that has the rubicon with 6 speed in my area to test drive to see if there is a difference but no luck yet. is anyone else having this noise? Is it normal??
