Hi guys,

This is my first thread/post on this forum and unfortunately it's regarding an issue that just popped up on my manual 370z.

During a spirited drive today (nothing too crazy though), my car started making a nasty buzzing/rattling noise that seems to be coming from the transmission. The noise is accompanied by a strong vibration in the shifter knob (stronger than usual).

The strange thing is that the noise and vibration only appears in 3rd gear between 4500 - 6000 RPM. It's not there at all below 4500 RPM and it goes away completely above 6000 RPM.

I think it might be also affecting gear 4 and 5 (in the same rpm range), but to a much lesser degree (I can barely hear it and feel it). I didn't notice it in gear 1 or 2.

The car drives completely normal besides the noise.

Here is what it sounds like. It's especially bad when I rev up to 6000 RPM and then let the RPMs drop (last 10 seconds of the audio clip).

Any ideas?
