Does the Allison grade brake perform the same as if I would manually put the trani in one gear lower?
Yes, but it will also upshift with a touch of the accelerator. The grade brakes drops ONE gear EACH time you hit the brake on a decent so if the road gets steeper, just touch the brake and it drops another gear until you hit 1st.
You can do it all manually, like people have done for years. It is just a convenience that some are willing to pay for on the earlier transmissions and enjoy on the later transmissions.
