All 2024 GM HDS get the 10 speed Allison.

[Pbutler97]

According to a sales guy, so take it with a grain of salt, the price will go up across the board by $3K to $5K for the 24 models. With the current state of the economy he is probably correct.

Exactly.

What is hilarious is of the two people who seem to have the most to say, one owns a Dodge and the other a Ford.

Lol! Good stuff!
But while on this topic can we give reviews of the 10speed in the Ford/GM half tons?
I’ve got one with 50k miles on it, light towing only. Maybe 20% of the miles towing 7klbs or less.
So far it is flawless. And the only trans aside from the Chrysler, sorry, ZF, lol, 8HP models that I’d consider on par with a 8HP, or digging back a few years, Alli 1000 or Ford 6R140.

Long term, anyone got 100k or more on these units?
My new work truck which I’ll own, not the company, will either be a newer Silvy/Sierra 1500 10 speed or a Ram 8HP.
I’m slightly more skeptical of the 10speed since no long term personal experience with it.

Are you sure? You might just have Allison emblems stuck on the hood or fender. It might be a 10L90E or even a Powerglide with 8 more gears stuffed in the housing somehow.

Well it worked! The deal GM made to brand their 10 speed transmission as an Allison is fooling many, who now think they have a real Allison transmission.

ROFLMAO....some of you take the cake.

So you think they are being forthright and honest???

Yes.

GM splitting off the Allison division is common knowledge as is the agreement put in place at that time. If anyone thinks the current 10L1000 is simply a branded 10L80 or 10L90 you've hit your head. Go discuss this thread with an experienced transmission guy and get an education. Or better yet perhaps you knuckleheads can argue about if the isolation bushings between bed and frame were made for all 3 of the big 3 by the same Chinese guy in Jieyang named Sum Ting Wong, or not.

But then again when I went from 9th grade in Jr High school to 10th grade in Senior High school I left Jr High school behind. Some didn't LOL.


I am however seeing your logic. So back to Jr High. Since from 1930 or something up until the mid 00's Allison was GM, I then assume that since RAM is/was a Chrysler/Dodge and the Ram logo was associated with same since about forever, and now it's a Chrysler/Dodge/Peugeot/Fiat branded as a RAM, it's all equal in the deception department huh? ROFLMAO

Maybe a little research is in order? I thought a Ford guy would have known this! Ford SDs are using the same Allison! :B

What difference does it make if the GM tranny is made by Allison or licensed from them? I have never heard anything negative about it’s performance.

I can’t say the same about the two antiquated transmissions in the RAM HDs……

I understand where you were going with calling shenanigans on 12Vs passive aggressive selective brand loyalty issues, but this ^ statement doesn't make sense to me.

Yes you are totally correct on where that was going. I was responding to 12V's saying that the engine was new in the 2020 truck. My point was it is the engine that was in the previous gen truck. I purposely called it an Allison to get generate a response from 12V. Surprisingly many other jumped on that, 12V not so much, but what really sucked was calling a Ram a Dodge, that has always been good for a response.....not a peep. I am losing my touch or 12V is getting used to his Ram being called a Dodge (which it is).

If it was possible I would gladly swap out the genuine 6 speed Allison in my motorhome for the GM 10 speed. Even an 8 speed. I am not a GM guy but I am pretty sure that the GM transmission is up to snuff. And, the genuine Allison 1000 is only rated for 30,000lbs GCWR. That is what held back GM's tow ratings for several years.

I also am fairly sure the earlier trans was the weak link with GM saying they didn't need to be able to tow 30k or whatever it was.

Don't disagree...
