4X I did lockout 6th on my 11 DRW with 3.42’s. On flat ground the mileage was the same at 62. It performed better overall leaving it in 5th. No down shifting on hills that way.
Mor important would be to know what my RAM would be turning if I had the same geared trans as the Ford 10 speed with my 4.10’s at 70 mph.
I'm not understanding what you're asking. The Ford 10 speed has a .632:1 gear ratio in 10 th gear .... same as your Aisin in 6th. So if you swapped the 10r140 for your Aisin it wouldn't change your 70 mph engine rpm.
