If he has a meter in the circuit it's going to affect the voltage that the PCM sees and that will result in weird temperature readings.
If it read 300°F that will set an overtemp code.
Later models had the tow/haul light in the dash instead of on the end of the shift handle. I think that started in 2005, but I'm not certain.
The place I went to was a diesel shop and not a Ford dealer. He hooked up his portable scanner to the OBDII port and that was it. I have no idea what brand it was, would guess Snap-On Solus because it was red and appeared to look like that.
I tested all the mini fuses in the black box in the engine compartment, all good. Then I replaced them (except for 2 amp) and tested them again. Call me crazy, whatever. LOL
Changed the TFT sensor. Put the truck back to stock tune. Reset the KAM using my SCT.
Did NOT get to drive the truck yet and did not unhook the battery cables at all. Started the truck and using Torque I came up with the same codes. Could be that I need to unhook batteries and/or drive a bit, or it is just that the codes are still there. Find out today.
I have seen on the forums a couple other people with the same codes I have, but what I haven't found is a real solution. The truck is for sale but I want to be able to tell any potential buyer in good faith that the truck doesn't have any known issues. Thanks again fellas.
Unhooked the batteries for a bit, then reconnected. Cleared codes.
Checked some more fuses under the dash. I did find fuse 107 Trailer tow battery charge was blown. Switched it with fuse 115 Upfitter control since I don't have any of that type fuse laying around and I don't have upfitter switches in my truck. Hopefully that doesn't affect anything until I get a new one.
Took the truck out (stock tuning) and drove it around the back roads. Some nice long stretches, hills, slowing down, speeding up, stop and go. Got her up to temp with some light to moderate acceleration. Put it in tow/haul and did the same thing. No issues at all.
Then I started doing heavy acceleration and WOT runs. Ran like a champ. All temps and everything I monitor with Torque looked great. Transmission didn't skip a beat, shifted great, no issues. Got back and checked for codes. Nothing except for the two EGR codes, P1000, and U1900.
So I guess my next step will be to load up the tune I was using and drive it for a few days to see what happens.
Loaded up PHP 200X. Drove around a bit this afternoon, easy on the throttle.
Drove probably 60+ miles this evening, a good bit of highway, back roads, and some stop and go traffic. Ended up doing some "spirited" driving as well. Transmission worked flawlessly! So far so good.

So had your truck been hanging out with the wrong crowd and the transmission
learned some bad habits somewhere along the line?
Good that is now back on the right track and behaving.
Yeah, I guess so. Guessing changing that TFT was the trick. Funny how changing that and/or maybe the trailer tow battery charge fuse fixed it and got rid of the B1352, B2900, and U2023 codes.
