I have the same clunk on mine. Its kinda random. When it happens I usually have a load on the tranny (going up a hill slow and pressing in the clutch). Its much less likely to occur on level or downhill runs (but on ocassions it just does it). There is a GM Service Bullentin on this, per my dealer, that says its a normal condition. I feel a similar random clunk when driving my daughter's 6 cly 6 speed Camaro too.
