Help Drive line Pro's

I have a problem that only happens every once in a while??

When I disengage the Clutch at about 3/4th throttle from 2 to 3 I get kind of a bang! It does not make noise but it seem like the disengagement is fierce! Kind of like it is being thrown to the passenger side of the car!! I think my Tranny mount is shot but would this cause the feeling I am getting??

I installed a clutch about 8 months ago when I did the 5 speed swap. All the Dowels were in the flywheel. And I used lock tight on the flywheel bolts. And the clutch was tightened to spec. the Bell housing bolts all seem fine! The Clutch is a king cobra behind a car that is putting out around 280 hp so what do you think!

The only thing that I can think is that it is the tranny mount! It is OLD and covered in grease and crap.

I'd check out the crossmember, a lot of them rust out especially where they bolt to the subframe.

I got under there the Xmember looks good but when I push the tranny with my hand the Tranny mount moves around alittle could that cause the felling I am feeling?
