Long story short my 2010 f250 4x4 6.4 auto is having tuning issues. Evidently my old mini max took a dump and caused PATS lock to engage numerous times. It's unlocked and I have a different mini max. It will tune the truck as a manual trans but will not tune it as a auto. I have even swapped in another tcm, when you check codes it gives u0101 lost communication with tcm... Going on a week now without my ride I need this fixed... I have updated the tuner.

 

Hi Jacob, welcome to FTE!

I'm going to move this one to the 6.4L forum since it's a tuning-related issue. Unfortunately I don't have anything else to add here, I've not heard of this happening before.
