I have an 06 Jeep Commander 4.7.155000. I live in the mountains. On occasions my jeep would go into limp mode an be stuck in 3rd. I would have to reset the computer. I warning across my dash. Transmission over temp. First I put an extra transmission cooler on. That helped. After I did that my jeep sometimes would have no acceleration. I got irritated an ran my VIN. Come to find out the jeep had federal recalls for the computer. There is a transmission recall. A transfer case recal and a ABS recall. took it to the dealership they programmed an update. My jeep runs like a raped ape. So I would suggest running your vin. The hole in the wall dealer I baught it from gave me a car fax. That didn't show any of these issues. Took me 6 months to figure this out.
