I agree with this, in diesel application, mostly towing on interstate, or anywhere that steep inclines are not involved.

IMO, the gassers have much more to gain, 8-9-10 speeds, especially the 6.4 Ram, to keep them in the ideal rpm, uphill/downhill towing.

I've no idea how many more moving parts are required, possibly affecting reliability, comparing a modern 6-speed to a newer 10-speed. If what you have, such as the aisin 6-speed, Cummins diesel, works great, no question reliable, for 30K+ combined towing, many would be hesitant to change to the unknown 9-10 speed.

Technology will always continue, time proven, to be for the best! It will be the cost of replacing older tow vehicles, with the latest tech TVs, that will keep many from moving forward.

Dang you are one smart DUDE!!!

I find these types of comments entertaining. The AISIN Medium Duty Transmission offered in the 3500, 4500 and 5500 RAM trucks simply does not break. With the straight six Cummins the 6 speeds works great. I tow much more weight than the vast majority on here at 35k combined West Coast with ZERO need for more gears.

My trans temp runs 165 towing or not and when climbing miles of 6% grades it may get as high as 172. OH and the trans is NOT tied to anything other than it's own cooler.

Cummins12V98 public statement just went into the archives for future reference. :W

As you being the RV,NET RAM expert you know this to be true.

Yes I'm the expert to predict your every move. If your truck doesn't have it and the competition does then it's not needed, but when your truck finally get's it then pulling the combined load gets advertised as great.

No doubt the Allison 1000 6 speed used with the Duramax was getting long in the tooth and at its max capacity as far as torque input was concerned. What is a real shame is that GM passed on the newly upgraded Allison designed 9 speed to push their in house 10 speed. I am sure it all had to do with money!
With that said and to be fair I don't believe any automatic transmissions is perfect when they are first introduced and I am sure the new 10 speed will fall into that category.

Check out the issues with the new GM 10 Speed/Duramax combo's:

At this point if you have this new transmission keep a close eye on it and get it in for warranty service BEFORE the warranty expires. If you plan on keeping the truck past the warranty you may want to consider an extended warranty or possibly perform some upgrades. Best of luck whatever path you take!

100% agree.

I have the '20 10 speed DRW and an '18 SRW, both are the same spec L5P. The comparisons are pretty interesting. I was good with what the '18 does pulling prior to owning the '20. The '20 is noticeable better. It simply feels like it has more power. The "dead pedal" is gone which great, but I feel the 10 speed makes better use of the power available.

Yup, and until you drive an 8 or 10 speed equipped vehicle, unless you really understand vehicles, I can imagine it is hard to realize what the difference is.
That said, 10th gear is all but useless in my Silverado. It's only 150 rpms lower than 9th gear, and 9th is still under 2500 rpms hooked to a LS motor at 90mph.

Don't anyone get too excited about an Alli in a Ram. It's not even a consideration at this point and was not a big consideration even 2 years ago when that rumor started...and died.

PS I rode in a ZF 8 speed auto trans Cummins Ram almost 4 years ago.

Opps the interweb strikes again.

12V98 saying you don't need more gears is based on your subjective opinion, but you don't have anything to compare your 6 speed against. You might just find that the pickup runs better with it (I don't know if you would admit that, but it just might). I would at least give yourself some room to acknowledge that the 9 speed, if that is what comes, might be of benefit. What if it made a good pickup, even better? You don't know, what you don't know.

Right?
After almost 15 years with Cummins Powered trucks and more with a couple Dmaxes and plenty of gasser truck miles thrown in for good measure, there is not a single engine today in a light duty truck that would benefit more from more gears than a Cummins.
Is it doing the job and doing it pretty darn well with 6 gears? For sure, not debatable. Would the truck with the lowest total rpm operating range benefit from shorter gear splits? Uhhh, yeah....
What pulls better? A semi with 10 speeds or 18 speeds?

The Allison 1000 transmission that is used with the Duramax is probably one of the best heavy duty transmissions ever made and unmatched in any other brand truck,

While it may have been underrated and extremely reliable at its rating it is no secret that the Allison 1000 held GM's tow rating back for several years. GM finally had to scrap it and build a new transmission to stay competitive with the competition's tow ratings.

I have an Allison in my motorhome on a Freightliner chassis. It is only rated to pull 5,000lbs because of the rating on the Allison. I have often wished that they had put a stronger transmission in it.

It was kinda funny when GM said something like no one wants to tow those kind of weights and stayed SAE rated way under RAM and Ford. Then WHAM a new trans and they were back in the tow ratings game.
