it can be a pain getting rid of the air . the way i done mine was take the slave cyl off the gearbox with the hose still conected loosen the bleed nipple hold it so the nipple is at the top press the rod into the cylinder this will force the air out tighten the nipple let the rod come out by its self make sure the fluid is toped up .you are using the slave cyl to suck the fluid through worked a treat on mine.
