My car was notchy going into 2nd, would clunk going into 1st if I was still rolling, and didn't like going into 1st and reverse when cold.
I changed the brake fluid to SRF a while back so I decided I should do the clutch as well. Bleeding the clutch solved about 80% of the issues. It's much nicer now. This was at 58K miles. That said, this trans leaves a lot to be desired.
