If last trans fluid change was unknown, you probably should have left it alone. Twice in my life I have had trans fluid changed on vehicles where it was an unknown IF it had ever been changed before-in both cases the transmissions started slipping within a couple of days and totally failed within a week. I know there will be arguements here, just telling of my personal experiences. Jeff
