Shift Knob Buzzing Noise High RPM

davle712 · 06-29-2018, 09:05 PM

Hey guys I got my 370z about 6 months ago and the shift knob has always made a really bad buzzing noise after 5k RPM which I thought was from the stock shift knob. After I replaced the stock shift knob with the M-Spec shift knob from Z1 the noise was still there.

I also removed the little metal piece from the stock shift knob which other members said was their source of noise but it did nothing.

I even bought a rubber grommet with a 1/2 inch hole like I've seen another member do but that did nothing as well. I can not figure out how to get rid of this noise and it's driving me crazy.

The homemade two piece grommet I made didn't stop the buzzing noise either.

Any help or suggestions would be greatly appreciated.

This happens in every gear or just certain ones?

After 5k RPM in every gear

Same issue with my vehicle at the same RPMs. Started after I swapped knobs.

Did you ever figure out how to fix it?

Installation of a weighted SS knob fixed mine. No more buzz in any gear or RPM. But in my case, the OEM knob was definitely the cause.
