that's new, never thought about that.

My mechanic pointed that out. He said something about driveshafts having an internal balance. I get the "screws in coffee can" sound, and rotating the shaft back and forth will get me that sound.

Sorry I was unaware that you checked every single 350 and 370 produced.

Funny you say that, my WRX is king of clutch shudder! I also noticed on the Z when I move from 1st to 2nd while moving kinda slow there is a thump when shifting, you can kinda hear it too. Anyone else get this?

:bowrofl:.......:rolleyes: it's been discussed plenty of times on the 350z site, and obviously in this thread its obvious the same applies.

Just picked up my Z today. Before I bought the car I never took it out for a test drive so was not aware of the issue. As I was leaving the dealer and I hear that same noise that everybody here is talking about. Its terrible! So there is still no solution to this problem?

i have the noise too...
 

has anyone tried changing the transmission oil? man thats like my car also.... it sounds like crap!!!! especially at low rpms in 1st gear
******* sounds like my tranny is ******* loose or something...

Yea I have the same noise. I hope either someone comes up with a solution or Nissan fixes it or something. I am going to try and change out my tranny and rear diff fluids this weekend and see if that helps.

The supra's getrag tranny does the same thing, but louder. It doesn't really bother me since I am already kind of use to it.

How does the auto trans sound in 1st to 2nd gear?

I swapped my MT oil over to Redline MT-90 a little over a month ago. Honestly, I don't know what everyone is complaining about. Everything sounds fine to me. Or maybe I'm just used to it and don't notice it, as I came from a 350.

Edit: I just played crbn_fbr's video (post 18). I have never heard this clattering sound on my Z. I did on my 350, but only after putting in a lightweight flywheel.

yeah mine makes the same noise taking off from a dead stop in 1st. how many miles does the car in the you tube clip have? i only have 1300 and mine does it sometimes, mainly when its warmed up a little.

I think it had around 1,500 miles in the video. At 3,000 now, it hasn't gotten any louder or less noticeable.

so does anyone know if this is normal or why these things make this noise?

Picked up my Z on Sunday and it has the noise when just sitting at idle. Noise goes away when you push the clutch in. I have a little chatter in 1st gear and when I shift into 2nd there is a slight noise. When going into all other gears there is no noise at all. My Z has 112 miles on it. Today I was thinking about this for awhile thinking if there was something wrong or if I was driving it wrong lol.

sounds like you guys are hearing the flywheel

If its loud, its the gears in your transmission its not uncommon for transmission gears to whine, the thing it is Uncommon for a new car to be making that sound, its a wear and tear kind of problem that develops. Just bug the dealership to warranty it, might as well got to get your money's worth off the warranty.

I just started getting a slight pop/pinging noise when I first start moving in first gear and in reverse, but not any other gears. It's never happened before.... I'll rev it up, slowly disengage the clutch, and as soon as the car begins to move it'll be like POP POP piiingggg then go away. If I keep it in first when I slow down and roll over a speed bump it'll do it then too.

Anyone else have this?

POP POP piiiingg....that definitely does not sound right.

I may have exaggerated the noise. Its not super loud and its like a few metallic pops. It only happens when I left the clutch engage with little or no gas while rolling or I don't rev up that high. The higher I rev the quieter it is, but its definetely new and a little annoying. Its the most noticable when I'm driving through my apartment complex and I'm alone/going slow because of speed bumps etc.

Just picked mine up this afternoon and already heard the noise as in crbn_fbr's video. Going back to the dealer on Monday. It sounds like a worn out 300K miles trans. Unacceptable for a new car!

you will have to live with it. nothing is wrong with it

when you say metallic pops it kind of scares me lol. i'd love to help you out by going out and getting into my Zed but it's out of commission after it was hit for a few days.

There are a couple of things going on. Based on this same problem initially originating pressent in the 07 350Z's the following noises were reported:

1. Clutch chatter - turned out to be a presure plate adjustment was required.

2. A similar but lesser volume chatter - turned out to be the carbon-fiber drive-shaft when it spins and was something that was not fixable....its the physical nature of carbon-fiber in shaft shapes when thye spin..they vibrate.

3. The shrill-like whine in 1st gear - usually an indication that the gears are not shimmed properly however most all 350Z and 370Z I have owned or been around have this shrill whine in 1st gear. It is so prevalent that I am beginning to think it is a normal sound.

My 370Z has #2 and #3 but I don't bother endlessly searching trying to chase these things down as there doesn't appear to be any damage occurring on ones that have been examined in the shop, including my 350Z that I once took in.

You are wasting your time trying to solve a moot natural vibration that occurs with all carbon fiber that is shaft shaped and spun.

its like a pinging noise of a spring uncompressing.. that's the best description I can give. Only when I ease the clutch out in first or reverse without revving it up.

I got an appointment at the dealer for wed...

Everyone hearing this noise, did u have a break-in period? I'm doing a 3,000 mile break-in. I'm being quite cautious. I was wondering how you'll are driving your vehicles.

doesn't matter how you break it in. its a 'natural' sound to the Z tranny

i just picked up my car yesterday and i have the same problem. it's not too much the noise that's bothering me, but the FEEL like there's some kind of slop in the driveline. it shakes and shudders and clunks. if you dont disengage the clutch just right, it feels like the entire tranny is moving and shaking around under the car.

my '99 miata had a very similar problem (although much worse), and it annoyed me so much that i'm gonna sell it.

some ppl have mentioned that their wrx has a similar problem, but mine has been perfect. i *love* the clutch feel on my wrx compared to this car. it feels tight and connected the pedal pressure is just heavy enough (the 370 pedal feels way too light to me).

most people are talking about the noise. but the thing that bugs me most is actually the *feel* that something's shaking and moving around underneath the car. it's the feel of "slop" and "free-play" and "jerkiness" somewhere in the driveline when the clutch is engaged and disengaged, and even while in gear. (esp. when you're driving slowly).

i guess i'll try to just ignore it since from what everyone's saying, it's probably "natural" for this car. but it sure is annoying...

well my car is at the dealer right now. Will be until Monday when a nissan engineer will be sent out from "hq". All the techs heard the noise, but no one knows what it is. They drove 2 other 370s on the lot; both didn't click and pop like mine does.

I'll keep everyone updated. As of now, nissan is covering a loaner for me and everything.

a loaner?
that's nice from Nissan

these noises as stated are normal. You CAN make them go away by changing your driving habits. A more smooth transition of depressing the clutch makes the noise go away. When you're shifting into 2nd, instead of just completely letting go of the gas abruptly, try transitioning smoothly. Let go of the gas in a very smooth gradual decreasing manner and then push the clutch as soon as it's completely off the gas. You won't hear the noise anymore. I can replicate this and make it go away as well. The Z is not the only car that's had this noise. It's just the nature of the tranny.

Those noises are actually a common thing on all Z! A 350z has the same exact noise when its in idle or so, Im assuming because we have a huge transmission thats why its like that! But hey, if its ur first time hearing it then just get use to it! im very much use to my car already!

finding this thread made me relax lol

i guess its your smoothness that matters here. the smoother you are the less noise you hear. i use to have the noise from the video when i first got the car but now i learned that if you dont rev the car enuff before letting go of the clutch the car will make that grinding noise. so you have to rev it above 1.5 k for it to not make that noise.

all those noises are making me feel depressed because i feel like im doing something wrong all the time but im not:shakes head:

turns out my rear axle needed to be lubed and re-assembled..... so yea my noise wasn't normal.

I have the same noise as well, but only after the car is warm.
If you have not heard it: after driving around for a while, try parking your car PARALLEL close to a solid wall or a solid fence. Restart the car, open both windows and put it into first or reverse and try to go forward or reverse slowly while letting out the clutch. you should be able to hear the noise.

Same Noise
 

I just got 370z yesterday,

and had same noise when push clutch to 1st gear.

got the same noise
 

Just bought the car today.I got the same noise from 1st gear to 2nd gear.

Took my car to the dealer to have them check out the noise. According to the tech it nothing to worry about, it is normal for the Dual mass flywheel used in our tranny. I personally still think it sounds like an old clutch with worn out throw out bearing and not something I expect from a near 40K brand new car. But I guess I have to live with it.
