Transmission noise (sound like bearing failure)

zpower86

What did the dealer say?

B&W, you may have a score in 4th gear if its the only one that you are hearing it in. If the pitch is changing with rev's than its just that gear that has a slight score. Is that a popular driven gear for you (maybe you drive side streats a lot?)

I'm pretty all over the map on the gears. I think 2nd & 3rd are my favorites for the corners I get to open it up in. I use 4th on streets between lights and for some rushour stuff but not too much. Most miles are highway miles and I'm in 6th whenever it's flowing. Need to pay a little more attention, think I heard it in 3rd today.

Pending on where you are consistently driving the car is where you will have the most wear at. I had that problem in my stang where 5th gear at 70mph I started getting a whine. When I broke my z in, I kept changing gears to eliminate the possibility of scoring the gear during break in.

B&W_Evader

Yeah, did the same thing on mine. Highway I made sure to change speed and gears. I do hear it on other gears. 1st- too much other noise to here it. Second has it, third has it 4th is the loudest, 5th barely noticable, and in 6th there's too much other noise to here it. Worst at 3k RPM. Loudest when there's barely any load on the tranny. Goes away when I put my foot into it.

Maybe it's the VVEL making some sort of whistling noise?

I had a '95 TT Supra that made chattering transmission noises when starting off from a stop. Mechanics told me it was normal. Then I had a 2002 corvette (bought new) that made the same noises. Dealer said it was normal. Drove it for 9 years with no issues. Now, I have an '11 Nismo that makes the same noises. I've convinced myself that it's all normal.

I consider it normal. My 03 G35 Coupe 6MT had the noise also after the first few months and I never had any issues with the transmission. I also have it with my Z and I don't think anything of it.

I know this thread is older, but it sounds like my transmission is making more noises than normal lately and thought it might be related to this. I can't for the life of me, remember how much noise is suppose to be normal and how much noise should be looked at. I'm having the same symptoms as the OP. A lot of noise (cement mixer, metalic grind) when I lift my foot off the clutch in neutral. With the normal cacophony of noises in first year it's really hard to diagnose the other gears just by listening.

Also, I think it might be normal, but I'm getting a slightly louder "clunk!" with each shift when the clutch engages. I'm letting off the pedal pretty smoothly, so I'm not sure what it could be.

I'm at 35k miles on the odometer. (I also have extended warranty)

I'll try and post a video later.

First, check your oil level(filler plug) Check for metal and/or take a sample (use a hose) of oil. The drain plug may have a Magnet, but have fluid for replacement. If it is that loud, there should be an indication of it in the fluid!

cmike did you ever figure out what the deal was Im at 34xxx miles and Ive taken the nismo to the stealership three times they always say its normal... It seems like its louder now im going tomorrow to see what I can find out.

Cmike2780

I actually had my transmission replaced due to a grind in 5th gear. It would grind in this sequence....1st, 2nd, 3rd, 4th, 6th.....and would grind if I downshifted to 5th. I managed to record it and finally convinced the tech to be on my side and the dealer replaced the tranny. The noise in the new trans is faint and not nearly as loud as my old transmission. I think it's a worn CSC that's causing the noise, but I honestly don't know enough about transmissions to give an accurate answer.

fuct

are you saying you would intentionally skip 5th? i think i read either in the manual or elsewhere its bad to skip gears because it messes up the syncros....

just throwing that out there.

Cmike2780

Yeah. I don't see how it would really cause damage though or if any of that has actually been proven. It's not anywhere in the manual and something that important would be clearly noted if it's an issue. I'm also not shifting to the point where it bogs down the engine. If anything, I'm matching the speed. I don't do it at all with the new transmission though. Just to be on the safe side. Maybe just on the downshifts every once in a while, but it can't be helped sometimes.

Arent these noises normal. Mine makes them to. When you shift its like something releases or some ****.
