I have a 2006 GMC top kick rollback wrecker. I've been getting a U0100 code with limp mode gear/wrench light. No MIL. I believe I have a broken wire but I don't have a wiring diagram for the TCM. Does anyone have one.

GM Upfitters has a ton of wiring diagrams for the kodiak/top kick trucks. Another source would be all data DIY.
