The hybrid aviator is getting a special version of the 10R it's not going to be the same one that's in the non hybrid vehicles.

It's going to be considerably less based on what? Cause the number 60 is less than 80?
The reality is Ford is not going to make a whole sperate transmission just to drop the final drive ratio from .80 to .60, it's cost prohibitive for them to do that. If it's like every other transmission they have put out it's just a final drive gear swap and maybe some small changes to fit it in the explorer.
The biggest difference when you look at the transmissions is how many clutches are in the clutch packs. For example the F150 has more clutches in the clutch packs than the mustang so it can handle the abuse from towing.
Question is which one did the ST get.... The car or truck version.
Related to the custom tunes I have a 5 star tune for my 3.5EB F150. They load all their tunes up on the torque side, look on any forum they are known for towing based tunes. I will not run their tune for multiple reasons but I'm not gonna open that can of worms now.
Bottom line for anyone getting a tune you need to monitor A/F, hpfp pressure, knock retard, iat2,LT/ST fuel trims an absolute minimum.
Just cause it feels good and runs ok doesn't mean the tune is safe.
