Hi, im thinking of replacing the old TCM in my Hmmwv m1045a2 with a TCM from US shift. Im having some trouble with my TCM and it is hard to troubleshoot the origininal TCM, I have tried to jump it to get fault codes but it makes no sense. So I think it is time to upgrade to a modern TCM
My question is how do I wire it to my hmmwv? Anyone done this before
What goes into the "Vehicle" port on the TCM?
"Solenoids" "PRNDL" "TSS" is OK but not sure what needs to go into the Vehicle connector. I guess it gets the 12 volt in that port to operate
Im also going to use a 24v to 12v stepdown converter, the one black dog customs sells
Thanks in advance
