Interesting specific mild buzz vibration in the gear shift knob, with the same note frequency as tapping the knob. It seems like a stray resonant harmonic. Knob not loose. It may be silenced by lightly resting hand on gear knob. Only occurs at a specific rpm somewhere between 2000 - 3000 and when transmission is not under load, across a very restricted rpm range. It doesn't sound transmission drivetrain mechanical. Gear stick itself is nicely steady.
Vehicle is a beloved 5k NZ new 370Z Nismo.
Can live with it but would prefer not.
Any suggestions, thoughts or insights warmly appreciated.
Thank you.
gear stick buzz vibration (resonant harmonic) at specific rpm
Thank you for your responses. Appreciated.
Apparently nothing to worry about and considered normal by the engineering gurus at Nissan.
The web suggests that the manual gear box is infamous for odd harmonics.
I removed the Nissan plastic gear knob and replaced it with a beautiful 700g stainless steel shifter knob from the US.
Problem solved.
