Thank you gm, very lovely... I love the 10 speed trash can in my 2021... I obviously love that it never stops shifting...

I wonder why gm hasn't gotten rid of 9th gear being 0.69 given that 10th is 0.64 making its existence pointless in my eyes. How is an additional ratio reduction of a meager 0.05 worthwhile to have? Gm already deleted a gear off their 9t in the new models.

Because 10 is 10% better than 9. 12 would be 20% better than 10.

Exactly. BMW 5-6 years ago said they would not venture with ZF to develop more speeds than 8, what they have now. MPG gains are meaningless.
 
Sad that they changed the software to alert you to a problem that will still exist ? epic fail GM. I suspect they are in damage mitigation mode right now since I havent seen a legit fix for this other than replacing the faulty designed valve by dropping the valve body. This also is essentially the same trans and valve body across all the gas 10 speeds as well but apparently the problem isnt quite as widespread presumably due to the lower TQ load. My guess (and I would love to see what the experts think) is that the design is similar across all 10 speeds including the imposter "Allison" units in the GM HD trucks. This is just further evidence that Allison didnt really design this turd box but rather they sold out and told what bandaids GM needed to get it out the door.

Guys complain about CVT's-in lieu of CVT's you are going to have multi speed transmissions shifting all the time. This is the world we live in until somebody comes up with a better idea.

My 10 speed in my 2023 Silverado half-ton shifts very smoothly-compared to the piece of garbage 10 speed in the 2020 F150 I traded in with only 43,000 miles on it.
 
Love my GM 10S and don’t like the Jeep 8S at all …
Maybe it’s just the V8 making the difference …
There is a lot about programming. I think one in JEEP is also made by Stellantis. They buy only high-torque version in RAM's from ZF I believe.

I got it flashed once - might need them to scan it again - too much “hunting” even with 4.10 gears …

Ford seems to have fixed their 10speed issues while GM seems not up to the task. This was the very same joint Ford/GM venture correct? I'm glad I have the 6R80. Doesn't hunt gears, smooth even when cold and overall pretty good transmission. I don't like how the 10hunts for gears in a friends F150 and 2 friends with SIlverado's have issues with a 2022 and 2023.

No issues with mine … Smoothest I ever had - hands down …
148° when it’s 90°F and 70 mph …

All I have witnessed, both anecdotally and personally has been the complete opposite.

That is not true, the Ford HD 10 speeds have valve body issues, having said that the early 2024 10L1000 gas trucks have a similar issue.

They basic development was a joint venture but thet they are very different software. Yes after AUGUST 2021 Ford fixed them- allegedly.

I have owned both-back to back, so I have "the experience".

I think that is JEEP thing.
Don't think so, none of ours hunt, and the one in our Durango didn't hunt, though it did have a firm shift into 2nd every time it was cold. None of the V8's have done that. I've owned 6x ZF 8HP's at this point, but only one of them was behind a gas V6. (3x GC SRT, 1x Durango 3.6L V6, 2x RAM 1500's, one gas, one diesel).
