Default New on here with a noise question

Ive got a 93 T/A Automatic bone stock (not for long). And recently whenever i get on the throttle there is a thump sound that you can physicaly feel and hear. It is almost as if somone is getting a good hit with a big mallet under the car. Anyone have this problem before?

Try searching either this forum or the General Maintenance forum for "Transmission Mount" and see if it sounds like the same problem you are having. That would be my first guess.

For what it's worth, as long as you are replacing it I would read up on Poly mounts versus stock mounts and see which one you think would work better for you, I know there are pros and cons to each but I don't know much more than that.

What he said^

I have a Prothane poly mount (you can get it at WS6 Store) that I put in when I did my clutch swap. I didn't notice a bit of increase in vibration.
