i know this is sorta costly (i use mobil1 atf, so think double,triple,quaddrouple ((sp?)) the price for me) but I would just drain 4 put in 4 (or what is needed to get to full) over and over again until you're satisfied. I did it 3 times a few months ago ($60) and plan to do it another time soon and then probably one more time before I go away to college in late 2004.
