I bought a Gold Center-force and the same problem I am having. The trans will not shift above 5000 rpm. I tryed a Richmond 6-spd than a G-Force semi clutchess 5 spd. I race both autocross and roadrace and both trans will not shift. I can get the trans out of gear but will not upshift or down shift above 5000 grand. The guys with no problems are running McLeod clutches or Hayes. Any body want a new Gold Centerforce???
