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.

The vibrating gear knob is apparently normal, too

Update: I had the silver-painted shifter bezel replaced and the buzzing/rattling noise is gone. This only happened during hard acceleration, usually above 4000 rpms.

my nismo definately not making noise at any rpm range..
well maybe shaking a little bit at high rpm but its not shaking crazy. feels completely normal to me...

I havent ever had any issues with tranny noise while driving, its only at a stop... at idle... its like a clack but not hella loud tho. Doesnt matter where I take it "Its normal"...

Most RWD vehicles do this to an extent. It's because the shifter is bolted directly to the transmission.

The Z's do have a bit of chatter at idle. Sounds like what you're hearing. It's normal for many RWD sports cars.

Tell you what... I was having the same issue. The vibration was so bad it was also coming through the steering column. I then found that the dealer had left 2 sipping spacers(one on each front spring) even after they advised they removed and handed me 4 spacers. After the removal of the last two spacers, the ride is sweet and the vibration is gone.

Yeah.......those spring spacers are a doozy!

I dont know how to embed videos but here is one of the noise at 5000 rpm. Sorry for the delay I finally got it up and now im losing my internet in 5 mins. I will follow up soon. Nissan finally agreed to fix my slave cylinder for my clutch because my clutch pedal keeps getting stuck and wont return up unless i put my foot underneath it

Well, 1 day prior to being hit by a deer, i was glazing my car and noticed a small peeling paint spot at the rear left fender joint where the rear spoiler/"diffuser" connects to the fender panel (directly above the wheel). Looks almost like it either wasn't coated thoroughly or it has been rubbing. Car is ~3 months old. I was actually going to swing by the dealership on the 5th (since their service dept would have been closed on the 4th). Mother nature had other plans for me though...

Plan on getting it addressed after it gets back from the body shop. I'd have the shop deal with it but it's on the opposite side of the car from the deer strike.

As for the motor, it doesn't sound abnormal/too rough that I've noticed and I owned another 370z prior to the NISMO car.

hey man i tried my car and its normal didnt hear any sound that you posted in your video ...

i only have sound while shifting from 1st two second gear but its not same yours ...


peace

The Z's do have a bit of chatter at idle. Sounds like what you're hearing. It's normal for many RWD sports cars.[/QUOTE]

I understand that but compared to other 370z owners the noise from my car is. . . . LOUD

Ya I get the chatter at idle too and that is normal. You don't hear it when you push the clutch in. I also get the clunk noise when I'm shifting from 1st to 2nd. Review my post with the video and you'll hear what I'm talking about. Car is at the dealership for the 40th time..... Clutch slave went out and it's going to take four days to fix. Hopefully they find the solution to my noise as they take it apart.

How did you get them to replace that? I've assumed it might be coming from there but it doesn't happen all the time just most of the time. Was yours the same?

I also get the rattle or buzz noise right at 5000 rpm, so I just make sure never to stay there. It comes from the shifter and if I hold it down a bit it goes away, so it's in the bezel or shifter. It's annoying for sure but it's a narrow rpm range that it happens. There is some weird resonance thing happening.

When your slave went out did it feel like you had no clutch pressure in the pedal?

Oh hey I forgot about that. This guy is 100% right. This is what's causing your rattle. Unfortunately, Nissan are a bunch of jerks who put loctite on your shift knob so it's impossible to remove without utterly destroying it.

I used a torque wrench (and a friend to hold the shifter steady) and just annihilated the OEM shift knob and replaced it with a smaller/lighter nismo knob. The nismo shift knobs replace that crappy plastic painted bezel with a rubber one that grips and will not rattle.

That noise annoyed the hell out of me.

The pressure would change over the year I was having problems tHe pedal would stick down and I would have to lift it up and it would grind gears when I would shift when the pressure was low. When it failed completely there was no pressure at all in the clutch pedal and it wouldnt return at all and I was unable to get the car into gear. For all those out there with 2009's that make this noise it might be silicone crud stuck in your heater core bouncing around. There is a tsb out about this and it may apply to me or it's in the shifter trim like previously noted. If your having pressure problems it's probably your slave cylinder in the clutch and when it fails it sucks. I'm trying to make Nissan replace all parts that were worn out as a result of this failure I have been complaing about for over a year.

If it helps you any, I had an '09 with that problem. Dealership said nothing was wrong with it until I had a catastrophic clutch failure at which point they replaced everything for free (clutch, flywheel erc)

Mine does not do this. I'm at 7500 smooth as butter.

Seems to be a common problem... I had mine replaced after it went out the first time. I had no pressure and I was 80 miles from home:(

Since then clutch has been good but lately I have been noticing the pressure is slowely going away again. Somedays its good normal pressure and some days 75-80% and about an inch less travel.

Soon I will be replacing the lines with better quality and Im thinking about an aftermatker raplacement booster. hopefuly that will solve the problem or stop it from happening again.

Reviving this to say I love this forum...guess I'm in the market for a new shifter bezel...does anyone know what's different about the replacements that prevents them from making those unbearable noises at 4500-5500 RPMs? Am I damaging the tranny by driving it until I replace it? It's a 2010 btw

I have a similar noise coming from my shifter. Usually at higher RPM's I get a rattle which sounds like it comes from the shifter. Took it to Nissan and they said it's normal. Caused by the torque at higher RPM's. Friend on mine said he had a similar issue on his BMW, come to find out his hood latch was cause the noise and the shifter is a focal point where is creates the sould. I put some mechanical greese on my hood latch and that seemed to work for a while. The noise soon returned. I'm going to try thicker greese and see what happens.

But I think the shifter bezel could be a cause based on this thread.

Your slave cylinder problem I had on my 05 G35 6mt. Turns out I needed special GTR clutch fluid. I couldn't figure out why my clutch pedal kept on moving down on warmer days.

Has anybody found a solution for this issue (rattling as in the video)? I have the same problem since a few weeks, my clutch works fine.
