Default Transmission clunking

New member and just picked up my new 2000 C5 without a single rock chip in the front. It only has 70,000 miles, bought from an original owner that really babied it, but it makes a clunking noise when shifting the gears and it does not due it all the time. It did not do it when I picked up the car but 250 miles later it started.

Anyone have an idea what this might be?

Thanks for any help.

the clunk comes from the rear area of the car and you hear it when letting out the clutch in the lower gears

Could be a universal joint and not the tranny... Also it could be the sway bar links or something like that.. Need to put it up and check it out...

You should not have any clunk.

Indication of rubber couplers going bad or a bad bearing in the rear.
