I have  lived with this problem for years and have always wondered why.
I had a  factory rebuilt motor and a new clutch installed by a local shop
and it  chattered immediately. It occured in reverse under a light load
such as  backing uphill, or in 1st under heavy load only. The shop replaced
the  clutch disk & pressure plate with new parts twice, but the  problem
persisted. I had so many problems with the first shop that I  finally gave
up in disgust. Later on, a different shop replaced the slave  cylinder, but
there was no improvement. I got fustrated with the whole  thing and have
learned to live with it. If I baby the clutch I can avoid  the chattering
about 80% of the time.

Walter  & others, when replacing a clutch did the flywheel get resurfaced ?
If  not then a warped flywheel could be the problem.  Also check the tranny
mount.  If the rubber has come un-bonded from the metal then this will  cause
the shuddering problem, especially in std. tranny vans.  Auto vans  will not
see much vibration but it will contribute to the demise of the flex  plate.
