If you're going to go with the standard advice and drain/fill/run x3 then you could use generic ATF for the flush process so long as you refill with genuine honda ATF at the end. Remember that each drain/fill cycle only replaces about 50% of the fluid in the transmission, so if you drain and add dexron you have 50% of the old, dirty fluid left and 50% fresh dexron. If you were to do another drain/fill cycle with honda fluid you're at 25% old, dirty fluid and 75% fresh fluid. 25% of the total fluid at this point will be dexron. Make sense? If not, then I'd just use Honda fluid. There is definitely a difference. You can leave behind a little generic dexron in the transmission, but it should mostly be Honda.
