After driving aggressively for a little bit, sometimes I hear a "rattling/tin can with rocks" noise near the transmission. I can only hear it when it's in 1st and 2nd gear on low RPMs. Also, the tincan sound is the loudest when I turn the car off.

I had this checked out by 2 NISSAN Dealerships but both say that the sound is normal and the car is perfectly fine.

I don't know if they are BSing to avoid fixing the car ( I have PowerTrain warranty) or it's that dual flywheel or the natural loud transmission noise that a lot of 06 350Z have.

Your input is very appreciated, Thanks

 

It's sounds like clutch chatter, and the noise it makes when you turn it off sounds like the exhaust cooling down. Both normal.

 

I could not tell you unless I drove the car.

 

Yep clutch chatter or aftermarket fly wheel. The low rpm noise in 1st and 2nd suggests a lightweight aftermarket flywheel.

 

I was wondering what that is.

Mine sounds as though it occurs from the High flow cats almost like a recoil effect.

 

everyone says its a normal sound, but its so loud and its bothering the hell out of me. ugh.

 

Normal.

 

My '06 does it too. Scared the poopies right out of me the first time I heard it, but I have checked and re-checked everything. Clutch is still WELL within factory spec for wear, and cats/heat shields are all tight.

Just a normal noise it makes.

Just rev higher or get a louder exhaust.

 

I have this issue too.

Saw in another thread where the lash between the gears in the transmission is what causes the noise, but it quiets down tremendously at 2k-ish RPMs. Coincides with what I've found on my car, at least.

ETA: Post I found this info:

Video of the sound? Can help maybe.

 

i will try to post up the videos

can the throw out bearing be covered under powertrain warranty?

 

I wouldn't trust the dealer to change my tires..
