  The automatic transmission of my '77 Plymouth Volare is producing a 
heavy thump when shifted from Neutral to either Reverse or Drive.
The harshness of the transmission engagement is roughly proportional to
the idling speed. The thump can jolt the car at cold idle speed (1400 rpm),
but is tolerable at hot idle (700 rpm). The level and quality of the 
transmission fluid has been checked out fine, the idle speeds are 
also alright.  Other than the stated problem the trasmission works fine
(no delay, no slippage). I would appreciate any pointer
to the probable cause of the problem. Thanks.
