2019 Freightliner cascadia shifting issues

I'm driving a 2019 Freightliner Cascadia automatic. These 3 lights randomly come on and when they do I have a shifting issue after coming to a full stop. Sometimes itll stay in 7th or so and I'll be trying to pull out and Itll take dangerously too long to shift down.
Tractor abs, hill assist, traction control lights all come on.
Works fine when off.
Any input???

 

ABS is common to all three.

 

While you’re waiting to get it in shop you can manually downshift when slowing down..

 

Put some holy water in the radiator, all joking aside it's probley just about the same problem I had but my 2018 cascadia got so it wouldn't start even though it was in neutral it would say it wasn't and it shifted weird at times.Shop put a new starter in it but that didn't work, something to do with the tranny mlp (9multi lever position switch) I think

Did anyone have this resolved. We have a 2023 Cascadia and the same thing is happening. Flashing lights and stuck in 7th when pulling from a full stop. When the codes pop up it also keeps us from using cruise control. This only happens when it rains also...
When I turn on the truck also a warning about abs comes on too

 

May be the wiring harness chafing on the bracket over air compressor.
