CL9 5AT weird noise?

[axispower]

When I am stopped with my foot on the brake, and the transmission is in D, there is a weird BRRRRRRRRRRRRRRR noise coming from the engine bay. It drops off after a few seconds and you can't really hear it after that. I'll take it to my mechanic next week to get it looked at... but anyone have any idea what's going on?

whens the last time you had the tranny fluid changed?

Last service about a month ago. It was not the Honda tranny fluid.
