Default Cobb Short Shifter Noise

I recently installed the Cobb Adjustible Short Shifter (no bushings yet) and it's brought along with it a noise in 1st and 2nd gear that resembles, to me, like something spinning freely on a lubricated surface. Only happens ~1500-2000 RPM in 1st and 2nd gear, usually when I pull hard into 2nd and continue to apply some pressure to the shifter while getting on the gas.

Any ideas?

Did you install the short shifter yourself? Did you tighten everything down? What troubleshooting have you exactly tried?

Took it all apart and made sure everything was tight, to no avail. There's not much of a window of adjustability on it-- 1cm lower and it'll hit the housing, and 1cm higher and it'll rub against the rubber, so I can't really adjust it much. I took a couple pieces of foam/rubber that had broken off from from inside the boot, but the noise persists exactly the same. I might try putting my original one back after putting in shifter bushings and a heavier knob to see if I even need the SS...

Maybe try driving around with everything including the center console taken out. That way you can really hear where the noise is coming from. If everything is tightened up I don't see where it could be making the noise. Did you make sure the snap ring is completely seated? Also, if it's rubbing against the rubber you can take some white lithium grease to lubricate it. I had some squeaking noise from the arm rubbing against the rubber but the grease fixed it up.

The snap ring is seated, and I did grease the rubber where it was rubbing. The noise I'm getting changes with RPM, but it isn't just the high pitched tranny whine--it's much lower frequency and sounds like rolling friction. I think I may try putting the stock back in to remember the difference and make sure the problem is isolated

Damn, thought that could have been the source of the noise. I put the stock shifter back in, and I'm still hearing it so uhh I give up

Lol there are many "noises" in these cars. You may notice them one day and they'll never seem to go away.

Check out this video. It's pretty in depth. Maybe you missed something in the install?

mine also rattles in second gear a little if i put pressure on it. if i bump it the noise will go away. i was also very careful and diligent with the install so im assuming its something that just happens.
i know its a little late, was just searching to see if anyone else experienced this.
