Whining Noise

I noticed that when im accelerating usually from 1st to 3rd gear the car makes a whining noise. It stops when i release the gas pedal and it does not do it when im in 5th or 6th gear or idling. I have a k&n cai and im thinking it could possibly be that, but i never heard this noise before...any suggestions on what it could be?

when you say you've never heard it before you mean your car used to not make that sound or that you havent heard it on any car? also does it make the sound if you are parked and rev the engine? your car may have a throttle body spacer on it and they will make it almost sound as if it has a turbo.. if you do have one i would recomend takin it of because they suck i got one for my car and it decreased low end power!!

Could also be transmission or rear end whine. Some is normal, especially the trans. If it is faint it is probably normal.

ya it could be the tranny but i dont think it would be the rear end because you would still hear it in sixth gear too because mine whines and sixth is when i hear it most

I have K&N intake and there's a definite whistle under certain rpm/loads. Almost sounds like a 'turbo'-y whine.
I love that sound btw.

You're describing rear end whine.... Car out of warranty? Still take it to the dealer and have them look at it they may be able to help you out. They can, question is will they? This was a major issue over the years. The first step would be to replace the oil and add new F.M. but this won't help but its procedure. The longevity of the rear with the whine was a concern.

The rear end is not a GM part thats why they were replaced and not rebuilt. Dana was responsible for this. Good Luck

The only problem with that was that I purchased this car from a private seller....so i dont have a dealer to go back to lol so wat would be the thing to do considering i cant go back to a dealer? Also it seems the whine comes from the front of the car not the rear though? Thanks GTO Judge

Did you check your power steering fluid?
