Is it smooth when it warms up? If it's just when cold, sometimes a better synthetic Dex III lube can help that.

I made mine worse by putting in Amsoil Dex III. I should have searched more before I changed it. Turns out some synthetics are a bit thinner than others and the TR6060 prefers a thinner Dex III when cold. The Amsoil works great at warm temps, but made my shifting - especially 3rd real notchy/grindy when cold.

I might try Mobil 1 or Royal Purple.

If it does it all the time, might be a synchro gone whacky.
