The noise starts about two minutes after the car is running and warmed up. It'll continue (at least 15 min I kept it in park and running) until the car is in drive at which point it immediately goes away.

It's not the fans because the fans don't kick on until it gets 180 (about 10 minutes). It'll do this fast high pitched sound for about 5 minutes without the fans running.

This is video/audio of the sound without the fans running. This sound started all of sudden. I went weeks without starting the car. I started the car last evening and it ran fine, but I didn't drive it. The second time I started it to actually drive/move the car...it did this and it's been doing it all evening. Below's the link.
