well after about a month and half of having my dual disc my clave cylinder is going bad. my symptoms are notchy shifting. hard to get outa and into gear. lighter pedal pressure. when i push in the clutch it sounds like it has sand in the cylinder. but you can pretty much hear the fluid getting past the little piston. just a heads up to all the other g56 owners who are looking into getting a 3250 dd or higher get the hd assembly no questions asked.
