NOT to be an echo, but I too have a worthless 2000. As for my head check, it has two leaks too! All the fluid flushs and filter changes did not help. I have old chevy and it has never had a tranny flush and works great. My thought is this is just a through away, and you may be better off never changing anything, just add gas until it stops, then donate to your favorite mechanic that over charges for the rebuild or R&R.
