UPDATE…
What a weird saga this has been. A bigger issue came up with my Yukon. The transmission puked. So that was a fun $5K I didn’t really want to spend.
When I got the truck back from the shop my son opened the LCD screen and it was magically fixed. I couldn’t believe it.
I imagine they disconnected the battery at the shop which I’m thinking reset the main dash unit which I never did. Or, the transmission reprogram / flash might’ve woken something up.
So if you have this issue just get your transmission rebuilt and all should be well.
