This is the second trip to the Chrysler service dept in a month for the same problem. While driving from a stop, the auto trans in the "D" (drive) mode, "locks" and starts out in 5th gear. This happened twice & my xfire went to the shop. About three weeks later, while stopped at a traffic light and then driving through the intersection the trans locked in first or second gear. I pulled to the side of the road, shut off the car, restarted & it seemed to shift properly. The next day ... back to the service dept. That was 3 days ago. They have not diagnosed the problem yet. Anyone here having the same problems or any suggestions/advise? Thanks!
