I saw one post here before, but never find it again. Please give me a link, I am going to do it this weekend. Thanks!

I don't think you can really change ALL of the ATF as a practical DIY project. About 1/3 of the fluid volume will remain in the torque converter. The only way you could get close would be to drain the fluid, refill it, run the car for a little while, then drain and re-fill. If you repeated this process 2 or 3 times most of the fluid would be fresh.

I'd take it to a dealership or other mechanic that has devices designed to change out all of the fluid. It connects to the tranny cooler lines and is kind of like getting a transfusion. It is the only way I know of to accomplish a complete fluid change.
