Happy Labor Day! Guess what I get to do today... Looking for some help/ideas. Anyone had this happen to them? I have a 2021 Mojave with 40k miles.
Driving home last night, dash lit up and car would not shift. Stayed in gear and I limped it home. Checked codes and got:
Cleared the codes and went to bed. Next day, fired right up, no problem. On the way back from picking up a new battery, some new codes popped:
I researched the codes and they seem to be related to the Transmission Control Module (loss of communication with), loose connections, a wire short, or low voltage (which is why I initially suspected the battery). I rummaged around looking for loose or frayed wires. Also checked the relays/fuses in ther fuse box associated with the TCM.
Went ahead and replaced the main battery since I have it. Hooked everything back up and nothing has changed. Had to unhook all the battery connections again to get it to stop humming. Any thoughts or similar experiences? Anyone know were the TCM is on this thing? Going to take it to the dealer ASAP, but at 40k miles it is now out of the 3/36 warranty period.
Thank you!
