Most of here has already switched to Mobil 1 ATF. Also some will add the friction modifier to the Mobil 1 ATF, this is called the "tranny cocktail" You'll need (3) quarts of Mobil 1 ATF which is about $18.00 plus tax and the friction modifier is about $5.00 or so. Most oil change places have the pump to evacuate and replace the fluid in the gearbox, shouldn't cost you more than $10.00 to have this done
