Po562 code

[davig]

So the other week I started getting the range shift inhibited on my truck. I had a hard time shifting into drive and reverse but would eventually go in. until finally it wouldn't go into reverse anymore but would still go into Drive still. so I replace the nsbu switch and now I have Drive every single time but I have still don't have reverse and I'm now getting a po562 code what could it be.

You're not getting voltage to the trans. Maybe ignition switch.

So i checked voltage at tcm and at the nsbu and everything looks normal

NSBU doesn't matter. It's the trim solenoids that are not getting voltage. How and where did you check voltage. Most people look at the wires and say they look fine. There should be 3 wires for voltage and 1 wire for ground at the TCM.

Honestly am not sure i didnt check myself can you tell me what pins to check so i can double check?
