If the truck was a factory auto, just changing the drop down menu to manual does nothing. Leave it as a 4L60e, disable every single transmission related DTC.
You also have to disable abuse mode, set it to 7,000rpm and 0mph. Disable the transmission abuse mode too. And disable brake torque mngt in the systems tab > system options, set it from 1 to zero.

I didn't really ask a question, I was just stating the facts. Maybe that gets lost on people these days.

Just toggle the switch in the flip down window to non-computerized automatic. It works despite what some claim.
