2001 International, no TCM communication
Posted to HD/Fleet Forum on 9/3/2013 7 Replies

I did a re-power and new trans in a 01 4700, has a DT466e with an Allison 2000 series in it. Did the work, truck fires up and drives, stays in default mode, 3rd gear, and has no speedo. Using our pro link I have no communication to the TCM. I've talked with an Allison dealer and they said sounds like a power ground issue but can't/won't provided me a pin out. I've gone over the harness looking for a nick or pulled wire and can't find any thing, any help that could be provided would be greatly appreciated.
