I recall from the early days of the 5th gen that there was a TSB or something for the shift fork, but I thought it was only for early 97's, and that eventually Honda incorporated the change into later model years. The part that fails would mess up the 5th gear shift, as the other poster mentioned.

I have had problems a couple of times (like grinding when I shift quickly), but when I had the fluid replaced with Honda MTF, it was much improved. Don't let the dealer just stick regular oil in it like they did with me once! (Just once!) I have it changed more often than what the owner's manual says (pretty much whenever it starts to act up). But sometimes, I still have trouble in reverse (although, not in a long while, knock on vinyl). In that case, I nearly always can get it after a "double clutch".

(I also usually get the valve adjustment done more often than required. Why not? Usually it runs better. Get the most out of what you have.)
