Run without TC?

Before you unbolt the bolts, see if they are tight. It could also be a cracked flywheel. But yes, you can start the engine with it unbolted, as long as you put the starter back in.

If it doesn't sound off I'm back to square one, then I hopefully will find something wrong with the flexplate. I've pulled the access points and looked at things. I couldn't see anything wrong.

Are you replacing the flexplate?
It is possible that it is cracking where it bolts up to the end of the crankshaft flange. Probably aroung the holes where the bolts go through.
Make sure the teeth are not worn on the flexplate or starter.
If a new flexplate is not too expensive, then "I" would probably replace it to be on the safe side.
I believe there are performance flexplates out there, but not too sure. It may be a smart thing to do at this tear down.
LOL, new tranny, new TQ converter, & new flexplate should rid you of the noise I would hope.
Unless.......at worst the rear main bearing is going, but I doubt it. The rear main seal would probably be leaking if it was. Just shooting **** out my a$$!
Anyway, hope you fix your problem!

It originally sounded like a "marble in a tin can" kinda thing. Now its much worse, with other weird sounds. Much louder and I can't really pinpoint where its coming from. Loudest under the truck but now very noticable with the hood up. I'm gonna pull plugs tomorrow just to have a look.
I have a new TCI flexplate in the garage. Waiting on the trans. A much mores solid unit compared to the stocker.
My fear is when I get into it. If I don't find anything wrong with the TC bolts, Flexplate isn't cracked, I'll not know what it is. Then I'll suspect the TC. FWIW I have not found any mention of anyone wiping out the Percision Industries TC. I've had two well know trans builders say "it's a PI? Well it is not the TC". At least if I can start it up with the TC unhooked and it doesn't make the sound, I'll know that it could still be the flexplate but not doing it because its not under the load of the TC and it isn't anything in the engine.
Was stressing it much more until yesterday. Its my daily driver. I went and bought a beater. A 93 Toyota Tercel So at least I'm not bumming rides to work.
Again thanks for the input guys. Keep it coming.

If you have cats still they may be bad,mine were at 46,000 miles on my 03.I thought it was a broken flexplate from sound coming from bellhousing area.Took it to tranny shop and put on lift.Trans guy would hit the cats with a hammer and sound would go away for a second or two.Took truck to dealership and got brand new y with cats under warranty because emissions warranty runs for 80,000 miles.
