Clutch Chatter

My '56 long bed has an unusual clutch problem. When cold, the clutch engages smoothly, forward or reverse, at any rpm. When hot, engagement is fine in forward gear, put in reverse- yeow! really bad chatter. This only happens warmed up in reverse. Truck has a 292, stock 3 speed (in great shape) and stock axle. Motor mounts, u-joints etc are fine. Could excess backlash in the ring & pinion do this? Or what?

Hi Steve, I would take a close look at your reverse gear idler shaft for excessive thrust clearance. Also, as your trans oil warms up, it will thin out some. That can make a difference also. So check it out and let me know.
