I have a brand new 09 Unlimited X 4 door with 2700 miles. This past weekend the transmission popped out of first gear and into neutral when starting from a dead stop - have to immediately shift to second gear. This has happened 3 more times since. It has only happened when starting from a dead stop in first gear and depending on the RPM the popping out can be quite violent - enough to hurt your hand. First time it happened I thought someone had rear ended me. I have it scheduled at the dealer. Searching the web I have found that this seems to be a fairly common problem but I havent found the cure yet. Anyone have any insights?
