Transmission acting crazy on tune.
Ok so I ordered a sct tuner with custom tunes from Mike at 5 star. Have not had the truck tuned a week and transmission has been acting up , like I put it in drive and go to take off and look down and gear selector says I am in 5th gear did that a couple times but I put it up in park and back to drive and that seemed to fix it. Now I go to take off after stopping at a stop sign and it don't change out of first , so I pull over and am now returning to stock. Any ideas what's goin on ? Truck has not been tuned a week and I have not been ******* it at all as a matter of fact I picked up almost 2.5 mpg on first tank with it tuned.

Simple lesson, don't tune your truck.
My Ford Service guy basically told me, who do you think has the better software, Ford, who spent millions with a team of the very best engineers out there, or a guy or two on their own in some garage somewhere. Made sense to me.

I didn't I don't think but adjust tire pressure for tpms that I actually wanted to turn off. That would affect the trans tune I don't think .

Keepin' the lights on!
Op- Flash to stock drive it for a while. If the problem still exists, take to ford. There have been a few folks with the same symptoms. The fix seems to be some sort of sensor on the trans and/or a software update.

Weird, mine never did this. I would find someone with a high end scanner (like a snap-on bi-directional scanner), and return it to stop and clear all the codes with the scanner. Drive it for at least a week then take it in to ford and have them
