You could try to put one washer in between the trans cross member and the floor of the car. This lowers the rear of the trans a little. I noticed when I did my swap the poly mount was a little thicker then the stock which basically raised the rear of the trans. The washer trick took care of most of my vibration.

I disagree - best mod I've done to date for my H/C car. Took all the shaking out of the interior of the car.
I also have the poly torque arm mount ( via a R/T torque arm ) as well as the ES poly tranny mount with no plate and shaved nubs.

I run a Prothane one and the first time I installed it the noise was bad.Took it out in an hour.Then I broke the stock one and had to reinstall it.After a couple weeks it was alot better(break in)but now I have a SPOHN torque arm,that brings noise in the car bad.
i heard it on mine too, dont worry you will get used to it in no time, i cant tell now and im about to do poly motor mounts....that will complete it all poly on the suspension now and i would never go back...

That s*cks, why on earth would they do that? That mount was the perfect replacement. They should have discontinued the stock piece of cr*p. If i had known that i would have bought a couple. GM
At idle I get the noise, but that is it.
Sure is better than the tranny tunnel getting slammed by the tranny with that stock piece of crap. It was a 01 mount as well. No good there. The poly has fixed all that!

I installed the ES poly mount today.Additional vibration is present in 3rd gear @ 2,000rpm. I took WILWAXU's advice and ground the preload bumps off with a bench grinder before install.

I most recently went to the local Chevy Dealer parts department (
), and asked to see the stock mount for my 2001 Z28. When he gave me the part, I was easily able to squeeze the rubber between my thumb, and index finger, it was that soft. The dealer wanted $125 for the part.
I purchased the "Prothane" trans mount for $24.95, and will have it installed next month.

whats the difference between prothance and poly?
why do you have to mod the poly?
what happens if you dont?
i may get an ES
my trans mount is cracked in half, held together by the trans itself.
i got three washers that make the trans wanna come up from under the shifter during the ol' 1-2
