Ive had this in almost all the auto's ive owned. Its where the box is half way through changing, then due to you changing the throttle position it decieds it dosent need to, hence the clunk happening.

You usually find that this only happens on simpler mechanical/vacum controlled boxes, and not on more modern electrically controlled ones, as these are far more precise and react a lot quicker....however the earlier style are much more reliable!
