I have a 2004Z with only 10k miles on it. Last night i heard a something that sounded like bad bearings coming from the tranny. I'm thinking it has to do with the clutch because when i press down on the clutch pedal the noise goes away.
This morning the noise seemed to have gone away, but I'm still planning on king it in to the dealer tomorrow morning.
Is this common on the 2003-4 model seeing that they seem to have tranny issues?

 

does it sound like marbles?? Bc that is common.

 

Yeah if it sounds like a bunch of marbles in a bowl then that is normal. Sounds like krunk kruunk krunk krunk. I have an 05 and it does that too...

 

Flywheel chatter maybe?

 

seriously...350Z trannies are the noisiest tranny ever made!!

 

Also could be your throw out bearing.

 

Yeah, it soundes like marbles. This was after having driven it for an hour or so, so. I'm still going to have the dealer check it out just in case.

 

I doubt anything is wrong. When the clutch is pressed in (disengaged) the engine is no longer connected to the input shaft on the transmission. Release the clutch and the noise comes back. It's normal. It's easier to hear when you're by a curb or a wall and your window is down. If the clutch is working properly I wouldn't worry about it.

 

well my 06 did that last night for the first time, or atleast that i have notice. I was like WTF it sounded kinda bad. but then i read its norm im like **** my honda never sounded like that ?

 

i guess the cement mixer syndrome in the Z is common.

 

Normal throw out bearing sound. I was worried about it at first but many Z's have that sound and i haven't had problems.

 

so its the throw out. so can you replace it with an aftermarket to lessin the noise or cure it?

 

Yea it sounds like my Z is microwaving Marbles for dinner....I tell people its bc i have to much hp...haha jk..but really...lol

 

It is NOT the throwout bearing!! A worn throwout bearing will make a noise when the clutch is depressed. The throwout bearing is what allows the pressure plate to freewheel while the clutch is pressed in.

In this situation the noise goes away when he pushes the clutch in, which is perfectly normal.

When the clutch is engaged/released while in neutral, the tranny must start spinning with the engine. This makes noise. When you disengage the clutch you will hear the noise slow to a stop.

It's perfectly normal.

 

Thanks roast. Why does the sound come and go? Today i heard nothing, but last night it was pretty loud.

 

lol i got my 06Z 3days ago... this power train makes all sorts of noises compare to my 06 rsx type s

 

Your car is normal.
This issue has been discussed many times before.

 

o.k i have not had this issue yet but if it's normal than thats kewl. good info guys

 

i have that marble rolling noise when i start to take off in first gear, especially on a hill (during the engagement time) is that normal as well?

 

What year is your Z? This could be the rear axle clicking issue.

Like others have said, the "marbles in a blender" noise is quite common.
