Is it sort of a faint whistle sound? If so, I have that when I take off from a stop moderately hard, doesn't matter if OD is on or off though.

 

Saltzy the sound you hear on take off is air being sucked into the intake. I heard it faintly with the stock box and it got MUCH louder once I got my C&L.. its not harmful.

I think the sound paulsoo is hearing is the same thing, though its wierd his only happens with OD off..

I have a whisling or turbine sound when I decelerate which is very audible when I downshift into lower gears manually when slowing down. I know its coming from the trans but I cant pinpoint what it could be.

 

Im thinking blinker fluid... possibly headlight out... but most likely blinker fluid

 

Classic case of low fluid level. I'd start there.

 

The car only has 6000 miles on it and there's no leak.

 

mine does the same thing... i just dont worry about it
