manual is different than auto. search it, that's where i found out how. you can use motor oil, but i just got a case of honda MTF. it's costlier than honda ATF, but i'm not gonna spend less for tranny fluid. why a case? i'm going to do drain and fill every oil change... about 3-4 tranny fluid changes. i personally wouldn't do the flush, so i'm doing the drain and fill method.
