    Transfer case dmax swap

    I had to swap the transfer case in my LMM duramax. Before the old one was taken out it was locked up so computer had it showing service 4wd. With the new on in the computer is not seeing the trucks transfer case in proper range so it the electronic shift doesn?t work and still displays the service light. Is there a way to do a transfer case relearn on Hp tuners?

    Did you try simply clearing your codes? Transfer case should be a simple encoder and servo i have never heard of a transfer case relearn honestly.
