My F-150 has a 10 speed auto. 33K and it works well so far. It is a bit heavier duty than the one in the Focus, I'd guess. I think the same transmission has found its way into the Mustang. But not the F-250, which has a very stout transmission.
Caveat - I've had some "tuning" done aftermarket, and it shifts much more decisively than it did from the factory. Ford, like all automakers, has pushed for that last MPG at the expense of drivability. Including short-shifting and engine-lugging low RPM whenever possible.
I had an F-250 with the 7.5 liter V-8.
It had the Borg Warner T-19 4 speed manual with an extra low first gear.
I worked at a Summer retreat in the Carolina mountains. There was one lookout which could be driven to on a road so steep that rocks would sometimes keep rolling down after the tires disturbed them.
I once tried a trick. My F-250 idled all the way up and down without my touching the accelerator or brakes. A couple of times I came close to hitting the brakes but never did.
