I had noticed the whine too, primarily when accelerating from a dead stop, or stepping on it to pass. Just did a drain and replace of the transmission fluid. Watched the video on how to do it. Very informative. All you need is a 6mm allen wrench for the pan cap and overflow tube behind it, a Torx 55 bit for a socket and at least a 12 inch extension for the fill cap, an extremely long funnel... and a lot of patience while refilling. Can only fill at a trickle... took about 20 minutes per quart!
