Default High Performance Tranny Mount Bushings

I replaced my tranny mount with another stock unit a couple of years ago, but I was still not happy with the results. The amount of movement in the shifter between gas on/gas off was considerable, even though my motor mounts were also new.

In addition to this, while performing very fast shifts from 1st to 2nd gear in autocrosses, the movement would sometimes throw me off a bit. I've put up with it for a couple of years now, but finally got fed up enough to do something about it.

Enter Ryan from Shook Motorsports ( http://shookmotorsports.com ) They are now offering performance bushings for the FB tranny crossmembers, so I thought I'd give them a shot. I'm very glad that I did!

The bushings appear to be of high quality, and the price is right since they are cheaper than the cost of a new tranny mount and perform better than stock.

Installation: There are two types of FB tranny mounts, and while either version is a simple install, the older type is easier than the newer. With the old type, the bushings are not actually inserted into the mount, so removal and installation are very straight forward. With the newer style, the old bushings will have to be pressed out, and the new ones pressed in (easy).

Although I installed the new bushings using the old type of mount, I'll also walk through the procedure of removing the stock bushings from the newer mount as well.

First off, here's a shot of the bushings and hardware I received from Shook Motorsports:
