First verify power in and out of the shift controller in each gear position to the transmission solenoids and verify it is switching to the different solenoids with someone in the cab shifting through the gears for you. If okay check the transmission oil, suction screen, and filter for metal/debris that would confirm and internal failure requiring disassembly and rebuild. Check for burnt smelling and dark/discolored oil as well. Let me know. We can follow up as needed. If clean and the shifter and wiring harness test good (common failure), the next step is to test the pressures for a possible pump or converter issue. Lube pressure is usually the first lost on a pump that is failing. If caught in time you can save the transmission and converter but over time it causes further damage. Check the neutralizer circuit as well to be sure this is not causing the transmission to remain in neutral.... Turn off the function and check that circuit for problems as well.

No power on any pin to the transmission harness is not normal... Test in and out of the shifter in the cab... See if there is power to the shifter but not out.... If so replace the shifter.
