The new transmission that will be going in the Dodge will be made specifically for the Cummins platform. (this was announced some time ago and should happen some time in 2022.

The 9 speed was orginally going to be used for the Duramax but GM passed on it in favor of their own new in house 10 speed transmission. When GM announced the new 10 speed I was curious why they needed so many forward gears. My 2013 Duramax worked just fine with the 6 speed an would climb a 6 percent grade at 70 mph pulling a 10k trailer and never come out of overdrive.
Personally, I did not believe believe the hype that GM said about their new BRANDED Allison transmission and actually called Allison to ask them about it. I was told by them that the branding is noting more then an agreement between GM and Allison, though Allison did lookover the design then did not have a hand in it nor do they have any involvement in the building of the new 10 speed. Not the case with the 6 soeed 1000, even when the building was supplemented to the GM plant do to the demand, Allison employee's were involved in the build. Not so anymore...
Please don't take these post as an assault on the new GM 10 speed, I just didn't want to be a guinnie pig for it especially after reading the problems with the co-engineered Ford-GM 10 speed used in other applications. I hope for all those who purchase this new tranny it proves out. I guess we shall see.
