I have a 99 Z28 with 42,000 miles, i just started hearing a winding noise, sounds like i have a super charger but i dont. I have the K&N FIPK and i checked all the fittings on it and they seem to be fine. What can it be? any suggestions would be greatly appreciated.

 

need more info. AT or MT? does the noise vary with engine speed? with vehicle speed? when turning? braking? accelerating? any other conditions when the noise is being made? later!

it is a AT and you cant here it at idle only when you put it in gear, it gets louder everytime the transmission is about to change gears.
