I have a 99 Chrysler 300m that won't shift out of 1st gear even with the auto stick. I have replaced the input and output transmission sensors and still no fix. I also did a transmission filter kit and still no change. My speedo works and there are no transmission codes present. What's going on can it be the TCM?
Scan the TCM for code/s could be a sticking shifting solenoid/s, you could also have it pressure tested to find out more-

There was no codes present on that which is weird. Also when I pulled the TCM shutdown relay there was absolutely no change to it. Still drove the same no shifting into 2nd. Do you think that the TCM has an issue or is stuck on off mode?
