Diagnosis help on nbsu
Trying to figure these tranny code to confirm a nbsu failure. Tranny indicator is intermittent and shows the physical signs/clunks of the nbsu problem, but here are the codes with the problem.
P0700- believe this turns of the check engine light
Unk. B1440 - no idea can't figure out
Tcm p0562- again can't find this definition.
Tcm po872- believe this is limp more if my research is correct.
So do these code match up with a faulty nbsu?
The truck is a 04 lly all stock! Not the one in my sig
