Two days ago I was playing wioth the car trying to slide the back around some corners and such. then yesterday whenever I went more then half throttle i would hear and feel a loud thunk that seemed to come from under my butt. ( no it was not farts! j/k) anyway today i get under the car to see what I could find. and i notice when I push on the rear of the trans. I could actually see the split in the rubber mount. so what I am wondering now is is the mount trash? or do I tighten it if possible. also if the mount is dead can I get a better one? like a polyurethane one? If they are made can someone tell me who makes them.

Thanks people
