5th gear "crunching" with shift

ZOperaMan

...this after about 8600 miles.

First time I noticed the grind was after a quick 1-2 upshift, then quickly laying off the throttle, shifting rapidly into from 2nd to 5th - ggrrrinddd.

Now after reading this thread, I'm dreading. I have experimented a bit, and the grind only happens when shifting to 5th from ANY other gear quickly (up or down). Does not seem to matter how well I depress the clutch. It works fine if I wait a second or so for the gears to sync.

It also seems to lessen the chance of grinding if I slant the 4-5 upshift more diagonally "/", rather than "N"-shaped, if you know what I mean. I'm just disappointed that I have to wait longer to snap into 5th than any other gear now. Other combinations that skip, like 3-6, and 1-3 seem to work fine.
