P0722 code

[armydawg1300]

Have a 2015 Chevrolet 2500HD, 180K, all stock. Started to town, CEL came on, and truck didn't want to shift gears. Scanner revealed P0700 and P0721. Replaced output speed sensor, and P0722 code now. Checked connector and seems good. Truck will barely pull itself under power now. Any suggestions?

Code reader will only give you a code. Scanner can tell you if thereis a signal. Then you can follow the wire from the TCM to transfer case.

RGR,
I'll see if I can locate a shop with one.

Easiest one to use ( because you have a '15 and Tech 2 won't work ) is an Autel. I use one at the shop and it reads everything on the truck. Mine cost 1800 and it reads any vehichle made.

Glad we have Ron Nelson here. He's pretty good.

Hopefully I located problem. Harness to TCM somehow was being rubbed by serpentine belt.
