All 3 codes are related to power to the Powertrain Control Module (PCM). There is a relay in the TIPM that supplies power to the ECM and PCM. Check the relay and the wiring on the underside of the TIPM. Also, check the wiring harness from the TIPM all the way to the transmission.
I've checked the PCM relay its getting battery 12v on one side and 12v on the other side dropping to 5v when the ignition is turned on.
Can't find much information or electrical drawings for the truck but i think that is correct?
Out of ideas of what to try next .
