For the past few months, I've noticed that the transmission grinds a little when shifting into 5th speed at 60mph or above unless I let the revs drop a bit between shifting out of 4th and into 5th. I spoke to a friend who experienced the same problem, and he told me that it was simply a matter of the gears/synchros wearing over time and that there was no way to fix it. I tried changing transmission fluid, but there was no significant difference.
However, a recent checkup made it clear that the seals on my clutch master cylinder were shot and I had to have it replaced (~$150 in parts + 190 labor). After replacing it, the clutch shifts as smoothly as it did originally. If you notice the same problem on your NSX, I suggest checking the clutch master cylinder.
