Noise In Bellhousing

This noise has been driving me crazy. For some time now, i have had a noise in my bell housing that sounds like someone holding something mettalic on a string and letting it hit a fan.

It used to come and go, on and off, but now its pretty steady.

I have taken the inspection plate off, but can find any thing amiss, no teeth missing or ground off on the flywheel.

None of the bolts loose or missing from the flex plate either.

It doesnt impact drivability at all, I just go clicking down the road.

A while ago, it would come and go, but now its pretty steady, and it didnt do it at all in park, untill recently.

It doesnt sound like its inside the trans or torque converter, it actualy sounds like it is inside the bellhousing itself.

Dont really know what could be inside causing this. Anyone else had this issue, before i go and pull the engine/trans out?

Try running it without the inspection plate, it may be touching the converter bolts or teeth. Mine did this also.

I think i did this before, but i will try again.

broke flex plate ... they dont always crack or break out on the ends they will break around the bolt holes up near the crank .

I was thinking cracked flexplate too.

If you need a flex plate i've got one you can have.

Sure, i will take it. Want anything for it? PM me the details

You guys were right, I took the transmission off today, one ear on the flex plate was broken completely, and another was cracked through.

Put the new one on and let it go for the day, i snowed here last night and its cold in the garage. Now I just gotta somehow, get it back on the jack and bolt it back up. not today though, brrrrr

Flex plates vary in thickness. Check the converter bolt length. Make sure they dont go though the nut blocks far enough to dimple the converter shell.
Good luck

I checked the thickness, before installing, it looks like the same thickness. Gonna let the garage warm up before laying on that cold cardboard on a cold cement floor to bolt the trans back on though.
