I never though such a little thing would improve performance but bleeding the clutch helps the transmission engagement greatly. I had a little bit of grinding on 3rd and 5th and thought it was the synchros going on those. I swapped for a higher performing transmission oil which helped but did not get rid of it. I bled the clutch and a nasty, black, fluid came out and performance is better than I have ever had. I even put a Speed Bleeder on which made it a 1 person job. I am glad I don't need to investigate a synchro service as I have heard nightmares in success or failure.
