From the research I have found I am happy that I can continue to use the 4L80e that I have lol. It was rebuilt in march so I have like 1-2k miles on it. From what I can see my only concern is the fuel pin connectors between newer models if I can't find a decent motor thats in my year range for direct bolt up. I didn't plan on doing a full rebuilt just the cams and heads to get rid of that nasty AFM. I was also given full bolt on exhaust from my cousin so that as well but I do want something reliable that will last me years to come for sure. Motor mounts for the 6.2 from 5.3 are also direct bolt ons and placement?

Do you know if there is a way to swap that part of the harness out or to change from 4 to 3 vice versa? I have a 2014 with 5.3 looking to swap to 6.2 and I have seen more later model 6.2s in DFW.
