Whistle/high pitch sound from engine @ WOT
Jsolo- It could be ice cold trans fluid. I only notice it under extreme cold when first driving. Fortunately, the engine puts out so much heat that it does not last very long

Dealership checked the belts and for intake and exhaust leaks. Nada. others have had similar noises. Best guess so far is A whistle from the airbox or benign VVEL noises.

Check to see if the intake resonators were removed. They are the empty plastic, funny-shaped boxes sticking out the bottom of the filter housing and on the two intake hoses/tubes. Mine starting doing the whistling after I put MAF tubes and drop in Afe filters. I also removed the resonators from the housing.
Edit: Parts lookup shows it was done away with in MY2011.
