Yeah I'm not sure why everyone thinks you own a dealer's used trans flushing machine...they hear 'trans' and 'flush' in the same sentence and freak out. Lol.

Just my opinion, but since the trans takes 6 or 7 quarts, I'd just do a pan drop and refill, with a new filter. With that much fluid, there won't be much old stuff mixed in with the new. Plus you can clean the crap out of the pan and the magnet. Just make sure the car is level when pumping in the new fluid.
