Nothing is more terrifying than being outside your car when it starts to move, and you are the driver.

If your tranny is really overfilled, you can either slip a thin (think fishtank air) hose down the dipstick tube and pump/siphon some out, or I suppose you could pop off the tranny cooler line where it goes into the radiator.
