I don't have one, but have been looking at them.

I would not expect a 10 speed until 2022 at the earliest. This is my biggest disappointment and one reason I may end up with Ford and the 7.3L.

I know the GM factories had a strike early in the year and then Covid hit, so dealerships where I am don't even have the **** things to look at or test. And they have stopped taking 2020 orders and are not taking 2021 orders yet. Applies to both Ford and GM.


My Chev dealer was ready to take an order for a 2021 HD a month ago.

Is there something wrong with the Allison transmission in GM pickups?

Other than it doesn't have 4 overdrive speeds mostly useless for towing?


Other than the gasser trucks haven’t had the Allison option since the 8.1L days, nothing is wrong with the Allison.


GM calls Allison: "We need more speeds... consumers want speeds!"

Allison: "Why?"

GM: "Because Ford has more speeds..."

Allison: "But Ford uses 140 cubic inch engines..."



Allison does not build transmissions for GM. GM licensed the name for marketing reasons.

I have an actual Allison 6 speed in my motorhome. I really wish that it had one or two more gears. You do not notice the gear spacing much when lightly loaded but as you allude to it is much more important when heavily loaded. Most people buying a 3/4 ton or up expect to load it heavily at times. My motorhome is always heavy.

Must be there are only 3 RVers that own a 6.6 gas engine, based on the responses. Must be many that go for the Duramax.

Ford's 10R80 transmission was a joint venture between Ford and GM. It is a light duty transmission used in vehicles like the F150 and Mustang. It is not an HD transmission that would be suitable in the HD trucks.

That is the result of dealers only ordering diesels to put on the lot. It is almost impossible to find a gas powered HD pickup sitting on a lot. Unless you want a white work truck.

There is some truth to that statement.
I just bought mine a few weeks ago.
My dealer ran a 250 mile radius trace for a LT double cab gasser.
There was a total of 1 on the lots.

I suspect that the 10R140 used in Super Duty trucks is closely related to the 10R80, just scaled up for the extra torque. I don't understand why GM took so long to do the same thing.
