Changes shift points (up and down) is the most obvious thing. I've read increased line pressure but some have questioned that so I'm not sure on that front. I can tell you tow/haul mode plus in concert with the exhaust brake gives you an incredibly good towing experience.

When I have my exhaust brake in auto and tow haul selected the minute I touch my brakes the truck 'takes over' and starts down-shifting and braking.

A good example is the first time I used them (tow/haul & exhaust brake) together. I was approaching a traffic light and it had turned red so I let off the gas and began to coast. You could hear the exhaust brake engage and it began to gently slow us.

The minute I touched my brakes, the tranny started rev-matching/down-shifting and the exhaust brake became more aggressive in slowing us. It was amazing. By the time I reached the light I barely had to touch the brakes to complete the stop. Aside from the initial touch to begin slowing (I let off once the truck started doing its thing) to the end, I didn't ahve to use the brakes at all.

I used to have an 04 Cummins so this was all new to me.

Great system.

Best description so far. In my mind, it can almost be too aggressive. It really won't allow you to "coast" with the downshifting. Too much deceleration. Personally, I would rather not use it most of the time.
