<strong>I am the guy that always replies to this question. The poly tranny mount is actually designed for the LT1, and it is a couple of mm's too tall. The top of the trans rubs against the tunnel and transmits a huge amount of noise at 2200 rpm aand up. The fix is to put one fender washer, with a 3/8ths inch hole I think, between the floor and the crossmember, at each of the 4 bolts that hold the trans brace to the floor. This will lower the trans back to stock height and the noise is basically gone. A slight vibration is normal, but noise like a helicopter going by is not.</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Does this apply to A4 and M6 trannys?? Also, do you know anything about thte two different part numbers that I were quoted? (See my post above)

Summit lists two variations on the Energy Suspension poly trans mount.
ENS-3-1108G = black
ENS-3-1108R = red
Price is 20.95 for both p/n's. It also states that the GM mount is a stock replacement for most cars from 1958-on.

Re: Poly Trans Mount ??? Hmm. OK. Guess I will have to just ask someone when I order. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Thanks for the info. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Re: Poly Trans Mount ??? I had a poly trans mount, and I loved it. I didn't think it was too harsh at all. However, when I put in a cartek clucth, Cartek told me that the poly trans mount had to come out, or else i'd have a ton of clutch chatter. I haven't been able to prove or disprove this clam, what do you guys think?
I am very interested in doing the shaved down polymount version. I wonder if that would work?

Re: Poly Trans Mount ??? How many people have shimmed the crossbrace down and what were your results? I tried it and it seemed like a little less vibration but it is a little hard to tell because there is still some there - although not much.
I understand almost everyone did not use the extra plate that comes with it.
Thanks
