The stock mounts use these little rubber wafers in between the metal pieces, its really sad. The stock trans mount is actually decent TBTH, way better than the newer cars where it lets the tailshaft move all over the damn place without an insert. But over 12-15 years... yeah...
And if you do replace all the mounts... I will say there is a good reason Energy suspension is more $$$ than the AM ones. I've had cheap poly mounts/bushings before. Never again.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
