Hey guys got an 04.5 duramax. Truck is throwing a p0846 code and stuck in limp mode. Trans is on a fresh rebuild with suncoast converter, clutches, valve body. Put 2 nsbu switches in, I have traced wires to look for breaks, checked continuity in every plug, still nothing, even changed out tcm with another that I knew was good. I am stumped has anyone ever ran into this?
