I just got a code of P0700, on my 04 2500 gmc 4x4 it state it is a trans. control module. Does anyone know how to replace this part? Thanks Dave

That code means the transmission module is telling motor computer I have a problem, you need to scan transmission computer to see what real code is.
I own transmission shop in norcal pm me your # and give any help I can.
