GM's New 10 Speed Allison Transmission

So bottom line it's a "GM Made" transmission, NOT made by Allison. Allison is granting GM to use their name!!!

I wonder how much different this transmission is from the Ford 10 speed for Super Duty trucks. I know that officially the joint venture was only for the half ton trucks but I don't believe that either one started with a clean sheet for the heavier transmission.

If they thought there was money in it to offer a manual, they would offer it. I think the take rate on it would actually be very minimal.

That's a lot of development work for you and the other 12 customers. ;)

The transmissions already exist. It is just a matter of being willing to install it and market it. There's plenty of demand for it, people just don't want derated trucks just to have a manual. A manual that would hold up would sell and did sell in the past.

This guy is stating that Chevy provides maximum torque in first gear at around 1:15.

Also I read somewhere that GM's new Duramax/Allison will not be torque limited in any gear.

So they are using the drive-line, U-joints, and rear diff out of a class 7/8 truck?

I would take that comment with a grain of salt. I probably should not have even mentioned it.

Lol, that would be a bit of overkill.... the big rigs still have up to twice the torque and are moving up to 3 times the weight of a pickup. Having said that, the rear axle is larger, IIRC about a 12" ring gear.

Too bad they won't just give us a 7, 8, or 9 speed manual instead.
