Good evening, what engine is in your dodge truck?

  • Check for the presence of other A/T related trouble codes
  • Governor pressure sensor has failed
  • Transmission valve body has failed
  • Transmission has internal damage
  • Governor pressure sensor reference (5v) circuit is open
  • ECM has failed

Those are the possible causes of P1756 I would start by Test the actual governor pressure with a gauge on the governor pressure test port. If it is 0 then it is an internal transmission problem. If the pressure is reading on the gauge then the problem is likely with the pressure sensor inside the transmission.
