I have a 2024 f350 i did a full delete kit on it and upon getting the new updated tunes after about a week the truck is throwing a p0771 code and a p2704 code it was fine with the original tunes but I was getting a p0181 code and a p160a code so the sent me a new tune and had me do a pcm and tcm relearn. Then on my way to work it threw the p0771 and p2704 which I cleared and it drove fine but after work on my way home I got those codes again but could not clear them I had to limp the truck home. Now upon start up I get those codes immediately and the truck will not move it hesitates to shift and skips into 2nd but can't move. The truck only have 5500 miles on it. Would this be a simple tuning error, a stuck solenoid or am I going to need a new transmission?

Put the stock tune back in and see if the issues go away. If they do, it's a problem with the tune. If they don't, check your trans fluid, maybe drain it and pull the pan and see what you find.
