Lite grinding from between engine/transmission

[DiamondStarMotors]

I have been on the forums for the past couple hours searching for this same problem to see if this already had been answered. No one described the same problem as mine.
No matter what gear, including neutral, I hear a lite grinding noise that gets louder with the engine revving up. It has really started to bother me.
And i am unsure of where to go as I am new to the whole wonderful DSM world.
Any help would be much appreciated. thanks in advance.

check your Alt. and make sure all the bolts that hold it in place are there.
i had this smae problem before and it turned out that i was missing a alt. bracket bolt.
