Transmission control not working correctly code 0103
I'm fighting an issue with my '07 Nitro R/T (125000 miles).
When it acts up, first the park lock gate starts clicking (like when you press on the brake pedal to pull it out of park) but this is happening when it is in drive.
The next thing it does is make it so it doesn't take throttle (5 MPH max) all the rectangles light up around the gear indicators in the dash, then the check engine light comes on, the code is 0103, lost communication with the gear shifter.
I also had it go into limp mode one time, 2nd gear but took throttle, I could go 25 to 30 MPH stuck in 2nd gear.
If I put it in neutral and kill the motor, start it back up, it operates normally until it glitches again. It may go 5 miles, or 500 feet.
I disconnected the battery for a couple hours after the first time it did this and it drove normally for about 2 weeks, then came back worse than before.
Has anyone had this happen to their Nitro and were able to fix it?
I've read it is probably a short in wiring.
I've looked at the connections at the computer, there are no burned connections, I'm getting ready to pull out the console to check the wiring bundle there, but I was hoping someone may know what the fix is, it looks like getting the console out is a PITA...
Thanks for the help!
