Hey, I searched the forum and did not find how to change all ~8 quarts of ATF. I have done this on many different cars with no issues. Simply follow the drain instructions found here, clean the magnetic plug off and replace, then fill the 4 quarts. Pull off the top right trans cooling hose, put the open end and a hose attached to the metal line into a gallon container. Start the car and let the trans' own pump go until it fills the gallon and slows down. Turn the car off, replace the hose and fill the next 4 quarts. Done. I like to use compatible Valvoline Max Life gallons from WalMart. If you want warm it up and undo the fill check like the regular drain instructions say. I did mine at 100k years ago, and now at 200k. The old fluid still looked pretty good.
