8 Speed Auto for HD trucks
Apparently, ZF is making an 8 Speed HD trans that can handle 1000 lb-ft. 2020 release date. I see it as the next trans in the Ram 2500 and 3500s. LINK

If they can make a 10 speed transmission with the required torque rating, I'm not sure why you would argue that you want less ratios to choose from for varying grade hills, headwinds, hauling weights, etc.
EDIT: Based on current 10 speeds, I would guess max overdrive will stay the same for the most part. But you will have less gear spread and much lower low gears without big gaps between them.
Just because you don't NEED it now, doesn't mean it isn't better.
I think its a great idea, gas or deisel.
Rebuilding a 47RE cost around 3-4K. Rebuilding a 6 speed 68RFE cost 7-8K. Not sure on Aisin, as I have not heard of a rebuild. Rebuilding a 6R140 or Allsion 1000 6 speed are similar in the 7-8K range.
Image what a 10 speed will cost to rebuild!!!!
