Transmission Linkage Slop

I've been chasing a vibration problem on my S2 and a friend's 89 2.7 car that used to be mine.

Tom, any chance you have the nylon bushing part number noted somewhere? I cannot find it listed in any of the 5 PET pdf's I have.Tom wrote: Tue Jul 12, 2022 6:00 pm I have an annoying vibration rattle that comes up through the gear shifter at certain rpms. Best I can tell, it's coming from the shifter rod (the one that runs back to the transmission). I've disassembled the shifter and have a nice new nylon bushing at the base, and greased up the peg where the rod attaches to the 5-year old shifter, but the noise is still there. I'm inclined to replace the linkage on top of the tranny, as I can get a metal on metal noise by moving it around. It shouldn't be this loose, right?

Looks like I may have misinterpreted your post. I thought you were referring to the linkage on top of the transmission.Tom wrote: Tue Apr 29, 2025 5:11 pm You mean this one?

Stuttgart Motors used to have an Al option but they are long out of business it seems.
Of course only944 has a solution, albeit a short shift. I am only trying to tighten up the slop while maintaining the original characteristics.

I talked with Kyle over at only944 about the same issue just yesterday and decided to just replace it all. You don't have to use his short shift linkage if you don't want to. The OEM stuff is available ... and expensive

Yes you can get that piece.Renn937 wrote: Thu May 01, 2025 11:53 am Yeah, the best I could find was $215.
What I want is sandwiched between both #21s. All you can buy is the #18 assembly.

I bought a new nylon shift block like the one in the video above and it completely eliminated all freeplay in the shift linkage. In fact, the new shift block fits a little tight, I had to push and twist to install it on the pivot shafts. It loosened up after a few miles of stop-and-go driving.
FYI I got it from from PartWorks. de Just search for artikelnummer 1266. The kit also includes a little packet of grease, new hardware and extra shims to eliminate any freeplay.

No, you were right -- that's what I was talking about, I just misunderstood what you were looking for. I'm embarrassed to admit I STILL haven't installed those parts. Been chasing other noises lately, so as soon as this one becomes the most annoying, I'll put the new bushings in.Renn937 wrote: Wed Apr 30, 2025 11:06 pmLooks like I may have misinterpreted your post.
