Anyone use this trans? How do you like it?

I guess the biggest question is how many speeds does it have? Also, how do you like it?

I'm thinking of putting in my Explorer, which may soon have a 5.0 from a late 80's 'Stang

It only lists a first and second gear ratio, so that leads me to believe it has two gears, or two with an overdrive.

EDIT:
Just checked again. Looks like it has an overdrive plus first and second. So I'ma say three.
