I assume Ford will use similar software on the SuperDuty's 10-speed that they do on the F150, at least from the user's point of view.
In Tow-Haul mode, on deceleration (or grade descent) if you apply the brakes, the truck will shift down a gear. Continued or firmer application of the brakes will cause another downshift, within a set of parameters like engine RPM, etc. As long as you stay off the accelerator (continuing your deceleration or trying to just maintain speed on a descent) it will hold that gear automatically. You can also use the +/- button on the shifter to "lock out" gears starting from 10th down, thus restricting the highest gear you allow the truck to use. I generally lock out 9th and 10th when towing the airstream, for example, because in 8th my F150 rarely needs to shift, and in 9th it hunts a bit if the road isn't level.
There's also a fully-manually-controlled mode, put the shifter in M and use the +/- buttons to order a shift.
