#328, "RE: ATF+3 is going away for good! (Just some info for you guys.)" In response to In response to 3
Could be just the way its worded but it says " ATF +4 maybe used in all transmission applications in which ATF +, ATF +2, and ATF +3 have been specified." So maybe they are just saying it will work as a replacement for them not as a mix with them. When I did the Final Drive mod Bob Kise had told me to use ATF +4 to top it off.
