Anyone know how many quarts of ATF the sienna 99' transmission will hold when doing a full flush?

it depends on what kind of flush you are doing. if you only pull the trans pan and clean the screen, it may take only 2 or 3 qts. but you leaveing 7 or 8 qts of dirty trans oil in the toruqe converter and cooler in the radiator. you should have all the atf flushed untill it comes clean(bright red) by pumping new oil into a cooler line to push the old oil out. then fill with the engine running untill it shows full on the stick. an extra trans oil cooler in front of the radiator will make the oil and the trans last longer.
