Get a "Prothane" mount, it is a better fit for our vehicles opposed to the "Energy Suspension", as stated above, Thunder Racing should have it.

Yeah the stock one's are not very good. Thunder will have it in stock.

Besides the fit what makes one better than the other?

Just the fit to me, the energy suspension is more of a generic mount, where as the prothane is made to fit the GM vehicles.

Hope that you have better luck than I did. I put mine in and it had the worse vibration you have ever seen. I pulled it out and went and bought a new GM mount and hadn't had any problems. Smooth as a cadillac.

I had a transmission shop replace the trans mount with a poly one when they did the TC install, I had them install a thin piece of soft rubber between the poly mount and the cross member, this eliminated most of the vibration.

I don't think that I will ever buy another one. They say the reason for vibs is that it is a little taller and gets the D/S out of alignment. Just one thing I 've heard. I know I had a bad experience with it and love my new GM mount.

I don't know, maybe I was lucky then, I DO have a vibration in the shift lever, however it is ever so slight, you can't hear anything, however you can feel it when your hand is on the lever. My exhaust sound inside the vehicle also got a little louder, I figure that is from the exhaust vibration going through the trans brace and the trans mount. I am using a quiet Dynomax Super Turbo muffler.
