Thanks rc 350 z glad theres someone that thinks this noise is a problem. Well I was a line mechanic for Ford and Chevy ,Ford for nine years and Chevy for eight years. There are not many noises that make me pull over but this one will at least the first time. Well they haven't heard the last from me. They told me there service rep would call me ,but its been a week. So its time to go see them again. What it sounds like to me is the output bushing on transmission is not getting proper lubrication,I ask the tech if he looked at the drive line slip yoke showed any sign of discoloration or scoring. He said it looked fine,but I really think he never looked. The point is I hope it hasn't hurt the transmission as the owners manual didn't tell me to bring the car above 40f before driving LOL. Also the noise has been getting worse with time so still have 54k and 4 years left on drive train warranty. I love the way my z drives other the noise and clutch. So easy to overheat the clutch and its soft.But I still love my zzzzzzzzzzzzzzzzzzzzz

took my car into the dealership today. gonna leave it there overnite and have a ride along with a tech tomorrow morning.
even at 70 degrees here in cali, i get the noise but it only happens for about a minute of driving.
during winter with 50 degree weather, the noise lasted at least 5 mins.
so is the definite solution to this problem "a new tranny"?

Orlando florida here. I have the same problem when it gets cool here. It doesn't have to be extremely cold. in the low 70's is enough. when it sits over night it whirrs when I take off, no high speeds no fast driving. it goes away after a couple of minutes. I do have a hard time shifting into second when its cold. I changed out my diff and tranny fluid to amsoil and the noise remains. I have 74K miles on the tranny right now.

I do believe the noise that you are all hearing is the throw-out bearing. The bearing seems to whine during colder weather because the grease seems to harden up or something. It is funny after all these years, nissan is still having this issue. I bought a brand new 1995 Hard body that was having the same issues. They changed the bearing but it still didn't change anything and Nissan came back with the same old its "normal". I put over 150,000 miles on my truck with that wine every time it got cold but never had an issue.

did your tranny whine everytime out or just during those times in the colder temps?
glad to hear you got resolution...and took advantage of the situation by adding in the goodies

just make an appointment with the dealership, drop it off early, wait there the next morning and have nobody drive the car until u get there and are ready to take the tech for a ride along.
i knew mine would make the noise as long as i had the car parked overnite and the dealership had no problem with me leaving the car and diagnosing the sound next day.

the noise only gets louder when its colder or if i haven't been driving the car for a couple days.
other than that, the noise is pretty consistent.
theres another member on g35driver Accordfreak who had the same problem and got his tranny replaced.

Guys, I had the exact some issue and i actually found this forum BECAUSE i was looking for someone to confirm what was going on...I have a '04 Enth. 350Z with 30K on it. I brought it to the dealer and they had it for a week trying to figure out what was wrong with it, (I live in NJ, so it's pretty cold here now) well they finally figured it out (hopefully)... they replaced the throwout bearing as well as the pilot bushing, and now all is well. no noise, and i've been driving it around in 34-45 Deg. weather for almost a week now.... i'd suggest getting those 2 parts replaced first, and see if you have the same success as i did.
NOW i do have one issue, ever since i got my car back from the dealership whenever i put the car into 1st OR reverse Gear and let the clutch out, there's a NOTICABLE "rough" spot right before the clutch fully engages.... my clutch NEVER had ANY issues before the dealership did their work to the bushing and bearing.... regardless of how many RPM's i gave it when going into 1st or reverse, it was always a smooth sync-up. Any idea what's causing this!? My guess is either the tech who "test-drove" it beat the heck outta the clutch, OR maybe an adjustment is needed after a new throwout bearing is installed?
ANY help on that little problem would be very much appreciated!
