This means that the clutch is not depressed and is engaged and the pilot buching is spinning at the same rate as the input shaft. With the clutch pedal out the only thing that can make this noise is the input shaft. This is the part that sticks out of the front of the transmission and intersects with the clutch, flywheel and pilot bushing. It is oiled through the process of splashing transmission fluid. When the car is at idle and in the morning you start your car and put it in neutral as the manual says. Well, the transmission is not moving any 75W80 GL4 grease and the input shaft bearings are getting cooked and that is what makes the noise. I find it interesting that a dealership can't figure this one out. Nissan is on the fourth redesign of the transmission to correct this and gear problems. Take the car in to the dealer and explain

I've had this rattle for over 25K miles, or ever since I've had my car. No problems with grinding gears; car shifts awesome! Does this mean thant my tranny is still messed up? My Nissan dealership says that this is normal.

Remember guys we might be taking about different rattles. Mine also rattles a little bit, very soft, when I get home after driving around, but I have to be very quiet and listen for it. It seems most definetly to be the release bearing (in my case). Other might be getting a tranny noise in neutral, but mine is definetly clutch activated...
In the other hand, the constant sqeak inside is probably NOT tranny related, it happens most often when my GF seats on the passanger side, so maybe is her butt...

it's out of loss of hope and desperation that i've decided to post this here...
I have been a lurker for quite a while now, learning about the Z out of fascination as well as being a Nissan fanatic.
I own a 91 maxima and a 94 maxima, both SE 5spds. The 91 has been parted out pretty much totally due to having a tranny problem and my not wanting to deal with it. Well guess what? the 94 I picked up started the same problem as well...the same rattling noise you guys are experiencing when the clutch is let out. The 91 started like that and progressively got worse till it started popping out of gear. Today, the 94 started refusing to go into gear and I had to wait a few minutes clutching in and out before it finally accepted the gears, after a cold start. I had researched this problem when I first started having issues *after* my first tranny rebuild with the 91 and from what I gathered from one performance tranny expert, he said the bearing being used by nissan was too small and he had overcome this problem by using increasing the size of the bearing holder to accommodate a larger, beefier bearing. Unfortunately, you have to rebuild the tranny to do that and that doesn't really sound attractive. It seems once the tranny has been touched once, it is never the same again.
Well, it seems that I'm not the only Nissan having this problem which is sort of a relief as I thought I was somehow adept at screwing trannys up. Luckily I have a spare I bought a couple of months ago and I am looking at swapping it in, in the next week or so. I'd advice anyone who has a warranty that's about to lapse to either get an extension or a new z because, believe me, it will only keep happening until you find a final solution to it which will most likely take lots of trials, errors and lots of downtime. Good luck fellow nissan bros. (and sis')

I replaced my tranny about 3 months ago, with almost 11K miles on my Z, I had 1-2 grinds and heavy vibration while the car was in gear and was decelarating rpm's. They replaced the tranny without question, since the replacement, i put 3K miles, i still have the vibration feeling while decelarating, and now i get this Hummmm or RRRRRRR noise when the car is in neutral and the clutch is out. I've been reading that many of you are hearing a rattle in this same situation, whereas, i hear a whiny RRRRRRR. Is there any difference or are you hearing the same thing?

my 04 g35 does it sometimes too. Once it was so loud i heard it with my radio on too. Then i turned down the volume and it sounded like a pulsating rubbing sound. ALso when i tap on the clutch alittle, I get a rough pedal feel.

The solution to this noise is Tranny replacement. There is a BAD bearing inside the Tranny and it's not worth repairing and Nissan will replace the whole tranny. They are replacing mine today. This noise is not coming from the throw-out bearing, even though it sounds like it (I thought this too), you should not have the noise on the 04 models though.

Here's a 4.57mb movie clip of the noise I hear when the clutch is out. I wouldn't consider it a rattle, more like a growl? Is this the noise you guys are hearing too and is it normal?
