John,

I wouldn't drive it anywhere - I'd drain what's in there, re-fill with new ATF, run it in neutral for awhile, then drain and re-fill again.

If the oil gets on the clutches, they will soak it up and start to slip. Once they start to slip, they will get hot and destroy themselves very quickly. Not what you wanted to hear, but I've rebuilt a few autos that this has happened to.
