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

I use the lock out feature when towing heavy. I just lock out 6th, 5th is normally good, with few downshifts, unless continuing rolling hills, in which case I lock out 5th, stay in 4th. Towing heavy with same truck/FW, but with 10-speed, I'd have to lock out 10-9-8-7-6 until past hilly area, then add back 6-7-8, until headwind, lock out 8-7. Maybe most will just not use lock out, let the 10-speed continuously shift, call it good.
Not against change, or improvement, but my Ford 6-speed is a great, user friendly transmission, with spot on gear spacing.

Jerry,
How can you comment which gears you will have to lock out when you don't know the gear ratios of the gears your referring to and you haven't towed with a 10 speed. Your assumption is the 10 speeds gear ratios 1-5 are the same as your 6 speed and I can assure you there not.
You are correct, I have no idea, but was only using the #s as an example. A new for HD 10-speed may not even have the lock out feature.
Time will tell, but my current 6-speed will be a tough act to follow, for heavy towing use.
