Hello all! I'm new here and need any help. 2018 2500 with a Cummins. I have no speedometer and the truck goes into limp mode when in 4wd. Replaced all wheel speed sensors. Replaced both speed sensors in transmission. No codes showing at this time. I used a Matco Maximus with the Chysler gateway opened to scan. We even replaced the TIPM but no change. HELP PLEASE?
