Some family members of ours are getting a used 1997 Honda Accord 4 Cyl Automatic. I have read here and elsewhere that the Honda automatic transmission are not the best. I reccommended that they service the transmission on it in short order. What is the best fluid to use for this application? I'm not sure what ATF the manual calls for on it, but I was thinking Valvoline Maxlife ATF with Lubegard black? From what I understand flushes are not advised on hondas only a 3X drain/fill?
