Wow. I'm still a little fuzzy.
So, if you step on the brake, not matter where the trans is, you get no unhealthy sound.
If you let go of the brake, even standing still (?), You do get the noise?
Is there any way you can get a decent quality recording of the noise and upload it and link to it here? Can you localize the sound?
If you only hear the sound when the car is moving, it could be something internal in the trans or it could be CV joints or an axle bearing.
Is it a manual or automatic transmission? (Automatics have flexplates, manuals have flywheels).
