So, a little over a week ago, I found an announcement on the forums from Kartboy offering a free transmission bushing to the first 10 people to reply, and I was the second to respond. I was a little skeptical, but it arrived within a couple days and has been sitting on my table until today.
So, got the car up on the jack stands, followed instructions (from Whiteline who offers the same insert. Kartboy didnt have instructions put together yet), and got to work tearing apart the under-side of the car.
It gets stuffed into that space, after taking down the transmission mounting and looks like the following pic after its done (i borrowed the picture from Whiteline because their insert is yellow and easier to see)
As for what it did..well..honestly..i didnt notice much of a difference. The shifting felt nearly the same as it did before (it went into gear a little easier without the usual resistance, but it was 80 degrees today so that might have helped). There might have been less vibration in the shifter, but again, it was hard to tell.
For free, it was definitely worth the effort. And for $25 (if i would have had to buy it), it still was likely worth the effort. Its not hurting anything, and maybe its helping the shifting feel a bit better.
