Like many others, I was annoyed with the extra transmission noise that followed the installation of Richard Paul's short shifter (which is excellent BTW). I haven't seen any real fixes on this forum to remedy the noise besides removing the green fuzzy thing, so I decided to take it a little further and dynamat the shifter area. Using about 1.5 sq ft of Dynamat Xtreme, this was the result:

I made sure that operation of the shifter did not chafe rubber or dynamat against each other. I didn't measure the decibel levels before and after, but my ear dyno says there's a definite difference, with the noise being anywhere between 50% to 100% quieter. I listened with my ear right above the shifter and also during daily driving. The noise is not only quieter but the tone of the noise is now more muffled and slightly lower pitched, not as grainy and trebley as it was before, if that's a good way to describe it. All I know is that the noise bothered me before, but now it's to the point where I don't pay attention to it anymore. The 3-4 layers of dynamat I attached to the rubber boot/shifter also noticeably reduces vibration (and hopefully noise too) about the same 50% to 100%. So now I have the same slick precise operation that RP's shifter is known for, with a lot less of the drawbacks! A worthwhile DIY for those who feel the green fuzzy thing removal is not enough. :)
Note: I did not try removing the green fuzzy thing first and testing it, so I don't know the difference between that and my method.
