I have a 2013 Dodge Durango Citadel.
I just wanted to post this for anyone doing research on this problem. Most of the forums I visited were dated years ago. My car will only drive in reverse and 4th gear. I'm in "limp mode". Sometimes I am sitting at a red light and it jolts in to 4th. I see a lot of people on different sites asking about this issue. Mine threw code PO750 and needs a new shifter solenoid pack. The mechanic wants to charge $1500 but I found the part for less than $400 online. Throwing this out there for the next lady spending too much time googling this
If you had the same problem, how much did it cost you? My warranty JUST ended. Lucky me.
