I assume that the fluid in our '93 got done at 80,000km, and I've just had it dine again at 170,000km. Used the genuine Honda stuff, and it shifts so much better now, especially when the car hasn't warmed up yet.
It's pretty easy to do if you can get to the right places, and find a way to get the oil into the hole, otherwise just buy the fluid and have someone else do it.
