Need 4-speed Help

I just went back and reread your thread and I remembered mine was similar.My problem was the bracket on the side of SS for the Z-bar not lining up properly.I had to drill another hole and bolt it straight.Problem solved.So check first to make sure your z-bar is working correctly,cause If it is off just the slightest,your clutch will only be 1/2 engageing,giving you the shuttering like a worn clutch.Hope this is your problem,cause that tranny is #%$&*ing heavy and awkward.Good Luck and keep us posted.$20 says thats your problem.:read2:
