Hello, i had 04 350z AT and lastweek i trade my 04 to 06 350z GT 6spd. i have question about the transmission or clutch. everytime when i go over 5000 rpm when i press the clutch pedal i hear chattering or grounding sounds coming from my clutch pedal. even the clutch pedal vibrates when it makes sound. i took it to the dealer and they said nothing wrong with the car? is this normal for Z 6spd? or is it something wrong with my clutch? now, the car has 700miles on.
thanks.

 

it only has 700 miles on it and you are going over 5000 RPM on a regular basis? Hell it's under warranty. Take it to another dealer if they aren't telling you what you wanna hear.

 

According to the dealer nothing is ever wrong with your car. I have a 2004 350Z and the transmission had a problem and wouldn't shift into 2nd gear above 5000 rpm. Instead it would grind and take me a few tries to get it into gear. When it was taken to the dealer , they said they drove it and nothing was wrong. I had to drive for them and show them the problem and then fight to have the transmission replaced under warranty.

 

I guess i've been lucky with the dealer. I've had two new trannys in the past 6000 miles. And you'd think they were getting paid extra to put new parts in my Z! I've had two new clutches, new flywheel, pressure plate, shift ****, and shift boot, all covered under warranty. AND got a no charge rental each time. And they never *****ed, or gave me the third degree. Yeah she spent alot of time in the shop, but damn near everything has been replaced for free. Kinda concerned cause it eats trannys as quick as it does. Makes me wonder if there is a frame issue or something. Cause i don't drive her super hard like others.

Hall Nissan in Va Beach BTW if anyoen is having warranty problems elsewhere. They are great!!

 

just came back from the cowles nissan in woodbridge. they said nothing wrong with my car. as expected. spoke to service manager. gave him a ride and let him drove my car. he heard bad grinding/vibration noise coming from clutch or the transmission after 5000rpm...he stated "this sounds like exhaust resonator" WTF. it is coming from the clutch pedal. even he said "i feel the vibration coming from the clutch pedal, but i think it is exhaust resonator" he said he will contact Nissan Tech Support to find out the problem? never heard of such as nissan tech support hope i can get it fixed this problem. wish me a luck

 

Go to passport Nissan in Alexandria.. They should help you

 

you're not suppose to take it over 5k rpm until 1200-1500 miles. correct me if I'm wrong. I babied mine until 1700-2000 miles. I kept it at below 4k rpm when shifting

 

Actually you're suppose to drive it like you stole it right off the lot. (I'm not even being sarcastic) There are various posts about proper engine breakage everywhere and it's not reccommended to baby the car even though that's the most sensible thing to do. You'd actually be hurting the car in the long run if you break it in like that.

 

Ummmm ^ did you read the manual??????? Lol Nissan specifically states not to take it over 4 thousand RPMS for the 1st 1500 miles.

 

actually i never pushed hard(Hard Rev up) to reach 5000rpm..i knew i had to break in correctly. that's what i did to my 04 350z also. but this car had 150miles on. and when i test drove around 4000rpm..i felt vibrates coming from the clutch..so i rev up to 4500 to 5000rpm(Not Hard Revving) then the noise was really bad. i wanted to make sure everything straight since the car had 150 miles on. also test drove 07 350z..reved up to 5000rpm then no noise...it was very smooth. is brown's nissan in fairfax any good? thanks for all your help folks

 

Intrigue yourself: http://www.mototuneusa.com/break_in_secrets.htm

If you don't believe me, believe the tuner god himself:
Here's to all "I read the manual" arguments:

 

Got 6000 miles on my 06 with slight oil consumption.. About 1 quart between changes which I can live with and I've been CRACKING 7K more then a hand full of times each week since 50 miles..

 

May be he should be hired by all the car companies combined so that he can make millions.

And about Sharifs comment, I respect it but dont believe it at all because I dont think he does anything related to engine design and analysis. He is a good assembler and tuner, thats about it.

So all the people who have researched all their lives about journal bearings, rolling bearings and lubrication theories are all fools compared to this guy. May be this guy deserves a honorary Phd.

I work with bearing analysis and lubrication for my work, but not with automotive applications, I can say this link is BS for me.
