^^^If it’s just about marketing I think 8 gears and a few more ponies would probably be enough for Ram customers to be happy. If it’s about actually keeping up to Ford up the hill the Cummins being a little higher revving makes enough torque at 1075 lbft but needs 500 hp at 2800 rpm to run neck and neck with the HO Powerstroke. I think adding 80 hp might not necessarily be that easy to do. It might be easy enough to just add fuel but meeting emissions and keeping the heat away may require some significant changes.

The video that the troller posted originally has nothing to do with the HO engine and the Aisin transmission. It’s the old 68RFE that can’t handle the high output.
So, without question, a 2500 would perform better with a different transmission (preferably with 8 or 10 gears) that can handle more HP and TQ.
And if we’re making requests, let’s do a ZF since they are one of the best. And no, I don’t care even a little if the transmission is outsourced.
My 11 HO DRW 3.42's with 68rfe did a fine job with none of the complaints from others towing 30k combined. Probably because I ran the HE!! out of it for the first hundred miles, trained it well. Nice firm shifts! The only issue was getting the load rolling on grade. If it had 4.10's I would probably still own it pulling 35k+.

^^^And if you're happy with 6 gears behind your 2015 Cummins you'd be ecstatic with 6 gears behind a new HO Cummins. Your 2015 is probably only making about 345 HP at 2200 rpm so someone could at least argue that a 2015 would benefit from more gears. The new HO engine will make more like 415 HP at 2200 rpm .... more gears certainly isn't going to make it pull a hill any faster. It might be nice to have another overdrive gear for running empty though.

I can see it now...Today a 10 speed in a RAM HD truck is not necessary, but in the future when they're standard equipment, it will be the best feature offered in RAM trucks and the praises will be off the charts.
The big question is who is designing this transmission for Stellantis?
You talkin this mystery trans that has been coming for years?????
