The 6L80 sounds nice til you add in the fact that you're locked into a more expensive Gen IV engine with VVT and the fact that the 6L80 doesn't have a 30 year reliability track record like the 4L80E. The GMT900 and K2 parts trucks are going to cost significantly more than a GMT800 C or K 2500 or 3500 with the LQ4/4L80E.I am thinking that I will use a trans controller and put this behind a non electric engine like the BT4.

AFM is a known problem child. VVT might, or might not, be a problem. More parts in the valve train generally isn't a recipe for longevity. I'm okay with VVT since I've worked on that before. I will delete AFM for sure. Probably the only way to go to get a low mileage engine.

If you have a 4x4 the NP208C & NP241C will bolt up to the 4L80 or 6L80 with a clocking ring to re-set the drop. The NP205 or NP203 will be a bit more involved but not terrible...

I wish I did have 4x4 but I don't
