Ok, so the rig is over at yotamasters (great guys) here in SoCal and they have my rig plugged into their machine.. throwing these codes they haven't ever seen before. They're trying to look it up, but can't find anything on their side..

AD83
AD84
AD85

In the ESA 1, 2 and 3.

Anyone got a clue?

Yeah come to think of it, that picture kinda sucks. Doesn't tell you much about what's really wrong. I read into detail on some other TCM codes and ADPro has some suggestions:

"Check continuity between ECM connector NEO terminal and TCM connector NE terminal. Check voltage between TCM connector NE terminal and ground. Substitute another TCM." <-- The latter is the first thing I'd try if your truck is at a Yota shop.

Edit: cruiserdan also mentioned ECU/TCU interconnectivity in this thread: https://forum.ih8mud.com/showthread.php?t=82625
A few posts down, Eric T suggests that a misaligned TPS could throw codes 83-85. Might be something to check since it's simple enough.
