I would suspect the 3/4 slider has cracked a bit and has worn the
syncro prematurely. Most 3rd gear syncros don't wear that much as there
is not the stress on the 3 or 4 shifts that there is on a 1st or 2nd.
 You might try some Redline  oil to see if you can milk it for a while,
but don't be surprised if it stays the same.
 Good Luck & holler if you have any questions.

Hello Volks,
The last few days while down shifting from 4th to 3rd gear my tranny
grinds a bit. Sounds and feels like the syncro's aren't doing their job.
Needless to say I imagine all sorts of things could be wrong... low on
fluid...famed 3-4th gear slider problem... syncro's.
Can someone tell me if they recognize the symptom? The tranny runs and
shifts great in all other respects... 1-2-3-4...3-2-1. It just grinds
from 4th-3rd after cruising at highway speed for a while.
