I got my 06 z about 2 monthes ago with 60000 miles. ever since ive been hearing a whine when I accelerate and only accelerate. when the windows are up and theres no music or ac you hear it more. is this normal?

 

aftermarket or factory radio?

 

I have an aftermarket radio but its not that. you can tell its from the actual car. its not a loud whine but noticeable when the windows are up and at a high rpm. the higher the rpm goes the louder it gets. can it be the belts?

 

Manual or auto? Does it whine when you hit the gas while in park/neutral?

 

its a manual. no it doesnt whine in neutral. only while driving

 

Sounds like it might be the gearbox. Mine had a very faint whine at 20k. Nissan replaced the transmission under warranty and now all I hear is the beautiful growl of the engine.

 

Check your tranny/differential fluids as well. Low fluids will also cause whining.

 

ok thanks guys ill check the fluid levels today if their normal i guess im off to nissan

 

Im a noob. how do I check how much transmission fluid I have?

 

Do you have a pop charger?

 

nope no pop charger but I do plan to get one

 

I have had this same problem. Trip to Jiffy Lube to top of the trans fluid fixed it.

 

Could be a supercharger.

 

is that happens when you are at high speed( 60~70mph)? Mine did that, but only at high speed. But i don't know about now...my car makes diff noise

 

im going to do the same. thanks!
