Had clutch cable & plastic clip changed a year or so back so clutch is fairly light & smooth, but still experiencing stiff/Clunky gear change. The gears don't crunch, but you have to be precise with the gear stick for them to operate properly. The gear shift has a gritty, almost un-lubricated sound/feel, but there was gear oil present on the last check. Maybe linkeage problems ? Any ideas folks ?
