2006 Jeep Commander Stuck in LIMP Mode HELP!
While driving my 2006 Jeep Commander with the 4.7L on the highway at 70mph the transmission down shifted to 4th and then proceeded to down shift again into 3rd. My pressure on the pedal didnt change at all and would not shift up. At the same time, the check engine line immediately came on. I proceeded to pull over to the side of the road and go through ur basic routine of checking the fluid, running through other gears etc and all checked out normal. But when put it D, it takes off from and drives in 3rd gear. After hours of research online I've determined that my transmission is in "limp mode". I have read numerous forums about this and apparently its a pretty common issue with commanders. Ive read all different types of issues referring to the transmission module, getting it flashed at the dealer, senors failing, poor wire connections. All the stories seem to be the "run around" of poor dealer service with no means of actual success. I bought my commander used with 28k miles on it and it now has just under 60k miles. Its used as a daily driver and I havent had a single thing go wrong with it (aside from the typical leaky sunroof which I've fixed). I love my commander and planned on getting an easy 200k out of it (as i do with most of my Jeeps) but from what ive been reading - the transmissions must be junk and it has me worried. Can anyone tell me what caused my commander to go into limp mode? Especially while driving at highway speeds? I have some mechanical background to know it must be an electrical issue but I havent found anything similar to my particular case. Please Help!
