My 3000 mile TKO600 5 speed does the same. Sometimes its good, sometimes it grinds. Hot and cold. Tried all the pre-selecting of forward gears, and never know what I will get. The fact that it sometimes selects reverse smoothly makes it all the more confusing. Iīve tried pumping the clutch several times to see to let the release bearing get a different take on the clutch fingers, but with no success either.
And it often makes you look like you canīt operate a stick shift just when you least need it!
