What causes a near new clutch to chatter??

What kind of condition was your flywheel in? Chatter often occurs when the flywheel friction surface has overheated on one too many an occasion and warps. There's a good bet that you're going to need to have it turned, or replaced.

Also....how's your engine?...specifically at the lower intake manifold at the rear? Many a time, I've seen coolant, or oil seepage run down the back of the block and make its way onto the flywheel friction surface causing it to chatter and slip as well. I'd first take a hard look at that before dropping your trans, to change the flywheel. It may be as simple as fixing a leak and going to town on the assembly with some brake and parts cleaner.
