Would you suspect this be in the 2020 Duramax - Granted 1000 series? Yourself or anyone have any insider info?

It is, GM has already released that. No word on engine package yet...

I posted this up here months ago. At this point we don't know if this trans will be in the Duramax. There has been talk of Ford and GM using the same 10R160 10 speed trans in the diesel trucks.

I think GM would be foolish to abandon the Allison in their 3/4 and 1 ton diesels. That is a major marketing tool for them.

Mike Jones!

Dodge Ram will be using the new ZF 8AP 8speed trans 8speed trans.

Are they still using parts out of the caravan on it?

 

[Dozerboy]

I don’t know that the Allison brings many people to GM. I bet most don’t even know about Allison outside of GM. It already has a bad rap among your average owner for being weak once you put on a tune.

They are basing the new trans off of the Hellcat 8 speed. The Hellcat ZF 8HP90 is probably the best car and light duty trans made. It's known for holding 1K horsepower in stock form. We shall see.

Ya but we can fix that. Dodge is hopeless.

Not sure if the Allison is made elsewhere, but the big factory here in Maryland that is just for the Allison is shutting down now.

Ultradrive in a Hellcat? LOL

That's where all the GM Allisons are built.

I thought I saw it in a GM public press release. Official data was it is only in 3500 so far, says 8speed for 2500 but that's probably just the addition on the 6.2 into the 2500 series. I would hope GM keeps Duramax Allison combo in 2500 but who knows...

Gasoline: the current models’ 6.0L V8 L96 will be replaced with a new 6.6L V-8 gasoline engine making around 400 horsepower and 450 pound-feet of torque, mated to:
A new GM 8-speed heavy duty automatic transmission for Sierra 2500HD models
A new 9-speed Allison heavy duty automatic transmission for Sierra 3500HD models
Diesel: the 6.6L Duramax Diesel L5P engine introduced for the 2017 Sierra HD will likely carry over with 445 horsepower and 910 pound-feet of torque mated to a new 9-speed Allison heavy duty automatic transmission

I saw that also, I just figured the 6.6 was a misprint? That would be a big gasser.

That means the Allison will be a hybrid with throttle off battery recharge.
