Cracked flex plate under NO load will often be quiet , unless it is really broken in pieces.
No load would be in park or neutral.

|bct||I drove the doner car into my garage, pulled the trans and put it into my 55. It worked fine before I pulled it. The only thing I did different was add a floor shifter. Now that I think about it I didn't have the original speedometer cable. I wonder if that could have something to do with it? Plus, I'm still not sure if the sound would go away when I put it in neutral if it was the flex plate.|

I'm having a very similar issue with my transmission. I just put mine in and it sat for a few years. I'm thinking with mine I have some rust buildup in the tranny.
What's the history on your tranny?

|bct||Would the sound stop when I shift into neutral if its the flywheel? I haven't put the dust cover on yet.|

flywheel rubs on the dust cover if there is one.

TH 350 Transmission
My Chevy TH 350 transmission makes what sounds to me like a scraping sound in all gears. The fluid is nice and red and doesn't smell burned. The trans shifts fine. While I'm going down the road I slip the trans into neutral and the sound goes away. The scraping sounds like metal sliding against metal and is pretty loud. Thanks for any ideas.
