Check all the rubber hangers to make sure the posts are through them all the way. Make sure any joints are tight and the manifolds are tight. Make sure any aluminum heatsheild plates on the body are tightened down. Is there a rattle? Could the element of your converter cracked?

 

Are you sure it isn't in the transmission?
