Rattle noise coming from bell housing

[Tbrown312]

A few weeks ago I started to notice a rattling noise at idle and I figured it was a heat shield or something to do with my exhaust. Well it started to get more noticeable so I got looking for the cause. I checked my exhaust and found no leaks or any place where it seems to be rubbing. The noise sounds just like a heat shield rattle until i put it in gear and then it goes away. I looked in the access ports on the bell housing and found no metal shavings or any sign of wear. I also checked the t/c bolts and they all seemed tight. Its annoying the heck out of me and i cant seem to find where its coming from. Anyone hear of this or had a similar problem??

Sounds like the flex plate may be cracked?

I pulled the starter and plastic inspection covers last night and from what i could see i couldn't find any cracks in the flex plate. I'm stumped on what it could be...

I should have mentioned the noise goes away completely when i put it in reverse and hold the brake, in drive the noise is still there but much quieter until i get on the gas and then it goes away.
