I used ATF+3 for a while and with that fluid it felt like it was sticky in gear. In other words it went into gear fine but pulling it out of gear it seamed to just barely stick in the current gear. So I switched back to mercon and it shifts normally again. Anyway just what I experienced, no other changes.
