depends on if you flush or just drain and fill it. i drained and filled mine. you need 4qts, 8qts, or 12qts. it drain 4 every time. i didn't change filter because you have to take the whole pan off. just drained it (jack car up some as draining, lower it to fill). after adding putting drain plug back in, add 4qts, start car, shift through gears a few times, and repeat as much as you what. the torque convertor fluid isn't gonna come out. and use mobil1 aft, worth the $$$$$.
