I was wondering if anyone had this problem.

When I am at low rpm, there is a loud vibration/grinding noise coming from the mid to the front of the car. It goes away when I am at higher rpm, and then when I shift again and the rpm goes down, it makes the same noise. This noise happens in 1-3 gear.

I thought it was the throw out bearing, and took it to the dealership. They said it was my transmission, and they would check my clutch. They replaced my transmission (under warranty) and they said my throw out bearing was fine. I get the car back and the noise is still there.
I'm taking my car back into the dealership this week. ANYBODY have/had the same problem?? Thanks

 

is the grinding noise at about 3k rpms???

 

The vibration/grinding noise also happens when I'm when I'm going pretty slow (10-20mph) and I press on the gas to accelerate....it makes a loud noise (hella embarrassing) until i reach a certain rpm...

 

It's around 1.5k-2.5k

 

They did replace your clutch and flywheel in the process correct? because if this is the first time replacing your transmission they are supposed to change out you clutch and flywheel as well (no charge)....thats what nissan did for me when i had a bad tranny on my 350z.

 

naw, I have a aftermarket JWT clutch....i guess i could have changed it out since it was already dropped but the clutch was in good condition.

 

did you check your tire?? i have the same problem, took it to dealer get new tire and noise gone.

 

was it at low rpm's too?? it's actually more like 1k-2k.....

 

Huh? You have a JWT clutch AND flywheel I am assuming? And you are wondering why you are hearing a grinding noise???

The JWT clutch and flywheel is your answer. Perfectly normal.

 

I know the JWT clutch and flywheel makes the grinding/vibrating noise while idle and the sound goes away when the clutch is engaged, BUT is that normal for while driving too?? not when shifting, but at low rpms (1-2k rpm)

 

Yes. Perfectly normal during low RPM acceleration--in fact, that is where it is most pronounced.

Don't let them "fix" your car anymore or they will eventually break something!

 

Ok so I get back from the dealership today, after looking over my car, and they said that I needed the oem clutch. They said the single plate JWT clutch can wear out my transmission. Should I change it back to oem or leave it alone.??? Thanks.
