GM Downgrade Braking?

[robh2]

I thought one of the big selling points of the Allison was the grade braking. I just found out all GM vehicles have it. The emotion controls system that GM uses has grade braking in it, like the allison, it sensing you going downhill, braking and other stuff and automatically downshifts for you. Anyone else know that?

 

Click the following link, scroll down to emotion transmission features, then choose downgrade braking.

I also learned on another one of GM's sites that Hydramatic (GM) makes BMW's tranny 5L40-E

Actually, you read too much into the eMotion page contents. It lists all the electronic powertrain control functions and capabilities. Some of which are optional or only available with various models, engines, transmissions, etc, etc.
