to do a trans fluid flush you will need 2- 5 gal buckets. put 12 qts of atf in one bucket and leave the other one empty.
you will use the transmission cooler lines to add new fluid and also purge old fluid. you will need to do some research to find the direction of flow but once you have that stick the hose that is drawing fluid from the cooler into your new fluid and the other hose into the empty bucket. start it, let it run until the fluid in the bucket with the new is gone. then you have done a full flush.
the drain and fill you speak of is only about 35-40% of the fluid.
