Clunk under the console as almost always the trans mount (you sure it's not the y pipe banging around?).....did you replace it with another rubber OEM POS? Are you getting excessive shifter movement upon hard acceleration? If so, it's probably broken again...I put in a factory one just to break it less than a week later, don't bother with the rubber ones, they are weak get nice aftermarket poly trans mount and you won't have to keep buying them.

+2 with the factory rubber trans mount.. Also have you checked your universals on the driveshaft.
