i have a 01 dodge 1500 5.9l off road package. i have a code saying p0743. i have a rebuilt transmission just done the other day. brand new everything they said. what would cause this? is my truck in limp mode? around 55mph its around 2500rpms. i dont know what to do anymore. should i reprogram my computer? could it be my crankshaft position sensor? a fuse?
