Im getting like a whistle or whine of some sort now during hard accelerations.Best way to explain it is a turbo whine almost.Starts about 4k or so and stays the entire way till shift.Happens in every gear and seems to almost be getting louder.

 

Probably the transmission, you can definately hear the tranny in this car... it IS only inches below the center console, with just the shifter boot between you and it...

 

read around, this has been covered in other threads. still no resolution however.
