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.

- Ford will also be introducing a 10-speed for 2020 model year.
https://www.tfltruck.com/2017/08/2020-ford-super-duty-10speed-automatic-10r140-f250-f350/ - 6 seems sufficient with the diesel but I guess 8 would be better. Would likely make a bigger difference on the gas trucks.
- With the next gen 6.7 CUMMINS having ALL the emissions under the truck the HP and TQ numbers will be much higher. If they can't make the AISIN handle the increases they very well may head this direction.
Time will tell! - HAHAHA == pretty soon we'll be spending all our time in the shifting mode, and no time in the driving mode. Can't wait for the announcement:
Ladies and Gentlemen, start your engines - we now have a twenty-speed Allison for your shifting pleasure. - Why can they make multi-speed transmissions but, the CVT doesn't seem to work properly or hold up on heavier duty vehicles :?
- That's exactly what I was hoping for when we buy in 2020!
I have the ZF in my Challenger and it is a great trans. carringb wrote:

Isn't that the 10 speed transmission for rear drive vehicles...that has been co developed by both GM and Ford ? In the past number of years Ford and GM have co developed/designed transmissions, also including front wheel drive transmissions. Good idea.gbopp wrote:

A family member had a CVT transmission in a new Jeep. Problematic transmission. For me if the vehicle has a CVT...it's a deal breaker, after this experience.monkey44 wrote:

With computer controls and plenty of gears, there’s no reason to shift more often. The system just has a lot more gears to pick from depending upon loading and can skip to whichever gear matches the demand.
Our Yukon 6 speed would probably act much like an old 3 speed at towing since the first 2-3 gears get you to highway speeds when turning high RPM. The upper 3 just keep dropping the RPM down. I find “holes” in the gear spacing just driving it empty. It really needs a 1.5 and 2.5 gear or maybe more.
Bring on the 8-10 speeds!
