Flywheel/ Throw-out barring "chatter"....

I'm still not understanding you guys when you say your hearing a whining noise. Clutch chatter in neutral and the 1st to 2nd clunk sound is normal and common on our Z's... But this is the first time I've heard about whining noise...

Not sure how else to explain it other than in first gear, I get a subtle mechanical whine from the transmission with quick acceleration. It sounds like straight gear dogbox race gearboxes as opposed to having the modern gear tooth profiles. The tech I had look at it said it was normal and this isn't the only vehicle I have had with this style gearbox that whines.

edit* and by this style gearbox I mean inline and under car, not transverse under hood. I realize the gearbox does not have straight cut gears

I second this.

I'm going to try and shoot a video when I can just for reference sake, but here is the best description I have.

When in first gear - If you steadily increase speed (rolling speed, not just engine speed - ie not just RPMs at a stand still), you can hear a subtle "whine". This is greatly augmented if you depress the clutch and leave 1st gear engaged while the car is still in motion.

Often when I experience this I am in first gear + accelerating and for some reason (usually traffic), need to return to neutral. I depress the clutch. In that instance, before I remove the car from 1st gear and return it to neutral - a "run-run-run-run-runnnn" in a whining fashion is herd....... That's my best attempt at describing what I hear.

Its isn't crazy loud, and you can't here it with the windows down or decent music playing BUT its there.

I have a 09 and mine wines in first and makes noise in neutral also. Glad its normal.

All I can say is I had a decent amount of noise when the car was in neutral when I first bought it - normal - and then when I switched to Torco oil, it got a lot louder but that is because Torco does not have all the dampening additives that most oils have. The clunk sound is definitely normal. The car is just telling you I "need to go faster".

Just my 2 cents worth.
