chattering/grinding by dat2

I have an '05 350Z 6spd touring with 3500 miles on it, and I have only noted some clutch chatter, at times, mainly when it is cold out. Also some notchiness or slight grinding on the 1-2 shift. Otherwise shifting and clutching is primo. I am coming from a 96 240SX with 170k on the original clutch and tranny. The 240SX, when newer, had a very notchy shift, but improved with age (like a fine wine?)...
 
Anyone else having any early mileage clutch chatter?

Just picked it up last week and hear a weird noise sometimes on start up and shifting 1st to 2nd. Is this the noise everyone is saying is clutch related?

The noise is not unlike a throw out bearing that has gone bad, kind of like bearings rolling around, hard to describe, but it only happens when shifting 1-2 and 2-3.

well, i'm still unsure of what you are describing, but there are 2 issues i'm aware of with the Z and tranny noises. One is a slight rattle that occurs when idling in neutral (i have this same thing on my 20-year-old alfa with 100k miles and the original tranny/clutch, so i counted it as unalarming). The other is the grind that many folks complain about, particularly when shifting from 1st to 2nd. Others seems to have more serious issues related to this, but it was only noticeable on my Z when it was cold.

Not sure if it's the same thing I had. But after 8,000 miles on my 2004 Roadster I heard a noise like some change clinking in the back(I thought I might have left a glass bottle in the trunk or something that was rolling around when I would start moving or shifting 1st to 2nd.)
 
I took it to Nissan and they said there was a TSB out for the rear bearings. They ended up replacing both for free. Not sure if it affected the 05's though.

I just purchased my 06 Z 6spd. I to also have mild stiffness/notchiness in first and second gear. I have driven stick all my life and when I brought it home and parked it in my driveway with a decent incline, I pushed in the clutch and it sounded like something was clanging around in the read of the car.
 
Took it back to the dealer and had them drive it to my home and the tech drove it up the driveway without the noise, he claimed that it is all how you push in the clutch. If i push in the clutch very quick it will make the noise, feather it slowly keeps it from happening.
 
I also have a clunking noise if shifting to quickly from first to second instead of feathering the clutch nicely....does everyone have this problem? I test drove two Z's both stick at two different dealers and they were both the same with the noise while shifting. Wish I would have found these threads earlier, although I love the car! Is there anything wrong with this noise, or is it just normal in these cars???

Have to apologize to everyone on here....I just read the message on the other page, but it looks like this must be normal for the Z's for the 1st-2nd gear noise.... the guy in the post before mine described it exactly as mine is behaving with 300 miles on it. Hopefully it is normal, I had a mini S prior to this as a toy and had TONS of probelms.

Have a 2004 Touring with about 10K miles. When I first bought the car I went to three different dealerships and had their service department test my car. Each mechanic said the 1st to 2nd grind was not a grind but simply the gear providing a notchy feel. Experience it going into 3rd as well but not as pronounced. Two things. I find a slow shift into 2nd will definitely produce a grind (so now no leisure shift;I always shift quickly). Also, if I make an effort to pull the gear shift toward me, rather than straight, as I go from 1st to 2nd it helps more often than not.
The clutch chatter is there as well. However, if I keep the clutch depressed at the spot where the gear begins to engage for an extra second or two, instead of continuing to lift off the clutch, the chatter doesn't happen. In other words I am sort of riding the clutch which I know is not a good idea and something I have never done with another vehicle. So in going from 1st to 2nd I never fully release the clutch but raise it enough to engage 1st gear and then quickly depress to the floor to secure 2nd. Result is kind of like speed shifting and vehicle accelerates faster (I don't mean spinning tires).
If you find another solution please let me know. Though I don't smell any metal heating up, likely I'll end up replacing clutch and related parts sooner rather than later. Good luck.

Agree, excessive clutch chatter is causing me to slip the clutch more than I would otherwise, which will likely result in premature clutch wear. 25k miles now on my 05 touring and chatter is a little stronger, otherwise car is performing admirably. 96 240sx has 180k miles on original clutch, and still feels strong, so if dealer says premature wear is user-attributable I will laugh.
