ATF +4 is what you really should use. ATF +4 works for all transmissions that used ATF +, ATF +2, and ATF +3. Its basically just a newer formula of the same stuff. But chrysler recommends ATF +4 for the A604. I recommend you buy a gallon of it if you do this mod. It cost me $18.24 for the gallon from Bob and it assures youll have enough to fill the tranny.
