The whole control module is held in place by 4 10mm nuts, and the transfer case is attached to it by 4 10mm bolts.Well, that looks like a fun wear part I’ll have to watch out for later… I guess the white plastic knob drops into something in the transmission rather than being bolted in?
I had the service transmission error on my JTR soon after I got it home from the dealer (400 miles). It happened intermittently on startup after sitting overnight in my side-sloped parking spot, so I suspected tranny oil level. One time the truck actually went into limp mode, but pulling over and restarting cleared it.
It went away on its own a few days later. I decided a dealer would never be able to replicate it and I never got around to checking the oil level.

You say it started happening after a recent software upgrade? I’ve had all manner of computer issues on mine. (I have to turn the update function off or the computer crashes when I shift into reverse if my phone is connected by CarPlay).
Can the dealer downgrade you to the previous version?
