Four problems related to transmission not go into gear have been reported for the 2007 Jeep Wrangler. The most recently reported issues are listed below.
The vehicle will not stay in 1st gear (manual 6 speed). You must hold the shifter, with force in first gear or else it "pops out". . . Makes a bad noise when doing so. I looked on Jeep forums and there are 5 pages or more of people complaining of this exact issue. Its a safety issue. If you pull into an intersection to make a turn, and are not holding the shifter with enough force and it pops out of gear, you might get hit by an oncoming car, since you've stopped going forward. Pulling away from a stop light or stop sign, the car behind you might slam into you, because you started to go then all of a sudden stopped going forward. This is a huge problem with these manual transmission Wranglers - this should be a recall. This is not a random occurrance. This happens every time.

The vehicle was taken to a dealer where it was diagnosed that the gear connector link failed and needed to be replaced. The vehicle was repaired, but not by the dealer. The failure recurred.

The automatic shifter linkage pops off and the automatic transmission will not switch gears. This is dangerous. You may think you're in park when you're actually in drive causing the vehicle to move forward unexpectedly. This will cause an accident, vehicle damage and bodily injury.
