How many quarts for auto tranny flush?

Hello Wayne: I am not sure how many quarts litres of ATF fluid to order. The order page says order 3.5 litres, however the capacity of the tiptronic tranny seems to be 9 quarts. In your reply below, you seem to refer to BMW... I am referring to a 2001 Boxster S 986.

Sorry, I got confused! The first comment below is correct - I would get 5 quarts to be safe, but if you want to flush the whole thing out, you would have to do it twice, which would be about 10 quarts (but only if you did the change twice).
