Could also be a hairline crack in the tranny casing. This happened to a friend of mine with only 350whp or so and alot of hard launches. Tranny can leak from where the input shaft comes out of the bell housing. I've replaced those seals on BMW trannies but have never needed to on a Honda, but I'm sure it is possible.
