I have an 01 2500 hd. This is my first diesel and love it. I have three codes showing up...
P0700 malfunction indicator lamp circuit malfunction (TCM)
P1781 transmission control module (TCM) MIL request circuit
P0708 transmission range sensor circuit high input.
I just put a new NSBU which I was told was the same as the range sensor and since I just changed it, it's going to take some time to clear itself. That only seemed to fix part of the issue. I did get back the gear indicator square on the dash but still stays in, I believe, 3rd gear once I shift into drive. PRN all work but shift with a clunk when I shift in and out of D.
Will a new TCM fix my issue or should I save that money and go right for a new/rebuild?
