5000 rpm transmission noise. Please check yours as nissan says its normal
 

Hey guys I need your help as I'm having this loud grinding noise coming from my shifter including vibration at 5000 rpm and above. So I had a specialist come out to deal with my peeling paint and this noise. I took the shop foreman and the specialist on a test drive and they agreed it was abnormal. One week later I get my car and they now claim all 370z's make this noise and that it's normal and that to drive the car at this rpm will damage the engine and transmission. I think that is completely wrong and before I drive 60 miles to find a dealership with a 370z with a manual transmission i want your opinion. It only occurs at 5000 rpm and above and if you move the stick I diminishes. It comes and goes but they won't fix it. My only option I see is going to another dealership and making them test drive both cars to prove that it is abnormal. Does your Nismo make this noise? Also with my paint peeling from the Nismo body kit anybody else have this issue besides the few on here that i know about. Thanks for your help.

Well that right there tells you they're full of ****. The car has a 7500 RPM redline, not 5000. If the noise is normal, then driving it at 5K+ is not going to cause damage.

There have been many complaints that, in general, the 6MT cars have an unusually high level of noise and vibration at high RPM. If that's all you're hearing, that's just how the car is and nothing to worry about. But really, only someone hearing it in person that knows what they're listening to could tell you for sure.

Huh?:ugh2: That's news.

I know the engine is going to get louder and vibrate at high rpm the issue is that the noise gets louder to the point where people ask what is that noise. On top of that the noise isn't always there and has disappeared before and then slowly but surely came back a few days later. So when it isn't there it sounds normal, the way I would expect it to. Yes It gets loud when it's normal but it's not a loud grinding noise that is dampened when you move the shifter, that is not normal.

It is really going to be tough to know what you are talking about. I suggest recording like either video or at least just sound clip of the said noise.

I'll see what I can do nikkolai. Funny though because they didn't do anything and the noise isn't there anymore when i got the car back today. It's obviously goin to come back so I'll get a video up when it does.

Might want to try a different dealership as well. You usually wont get the same diagnosis at different locations.

yo ef those guys


they brag about the 7500k redline so wtf is 5k?

I was told the same thing by Honda with my car, wound up getting part of the transmission replaced under recall a year later.

If it's bothersome enough to you, keep pressing it. And go to another dealership, if they're telling you that 5k engine speeds will ruin the motor, they're just preying on someone they hope doesn't know anything about cars.

OP, have you found out what it is? If I am in 1st gear and rev up to 5k, it gets really loud and vibrates hard.

Mine makes this noise too. Mine kind of sounds like static interference but it comes from the shifter. At first I thought it was coming through the passenger door speaker but I turned off the stereo and it still does it. I thought I saw a thread about it but now I can't locate it.

I think the static youre hearing is the clutch. If you push it in it should go away. We are getting loud grinding at 5000 rpm. Still unresolved but I'll take it to another dealer when I get a day off.

Yes it should go away if I disengage the clutch since the transmission won't be vibrating as much. Does not sound like clutch noise though. Kinda sounds like a taser being unleashed on someone, but faster. lol

I think my issue is unrelated to the OP's. Just took mine to the dealer and they are ordering a new shifter bezel trim panel (silver painted piece with everything attached to it excluding the actual shifter/knob).

The humming while idle I believe is normal. Grinding at 5000 rpm isn't. I'm going to test drive another one today and I'll also try to make a video of my noise today so you guys know exactly what I'm talkin about.
