Weird transmission noise ??....video of sound

Hi hope someone can help me diagnose this... Thanks!
Well the transmission is making a screeching noise that sounds like metal on metal. The noise only starts to appear after the car has reached normal operating temp and is warm. And only makes the noise at idle or low rpm when not under any load. If its revved up or anything the noise will disappear. I checked the fluid transmission level and it seems to be fine. Not sure when the last time it was changed though.
I also changed the cam synchronizer to eliminate that making that noise since it sounds somewhat similar to a failing cam synchro.
The noise doesn't start until running for about 10 minutes and only makes it at idle under no load. The transmission seems to shift fine and the car rides nice.

Here is a video of the sound coming from the transmission.

Without a stethoscope check, it is hard to determine what it is. Could be a trans front pump bearing failing, but it could be something else too.

Thanks for the reply! I actually bought a stethoscope earlier today! I had it around the area of the transmission but couldn't determine where it was coming from.. all I could tell was that it was coming internally from the transmission. Maybe I should try the stethoscope at it again.....try and determine if its from the front of the transmission or the rear of it. Any other suggestions are helpfull! Thanks
Thanks again!

Sound can travel a ways, and a squeak can sound as it is from one part, but it ends up being a completely separate part.

It might be the torque converter too. sometimes if the bearing in that is failing, it could cause a similar noise.

Not sure if it applies, but scrapping noises on a Vulcan can often be the
water pump impeller scrapping the inner housing because of bearing wear.
a bad idler or tensioner can also cause some strange noises.

the shut off noise chirp sounds strangely like the sound of a failing shop vac bearing.

Not sure what kind of noise failing TC splines might make.

If it is an internal trannie issue, you might have to wait until it gets worse
or drive it until it dies. Unless you want to pony up $2K or so for
a rebuilt and new TC.

Thanks for the replies! The engine actually has a newer water pump installed on it....but the sound is definitely coming from the transmission side. I kinda hope its just the torque converter... don't want to have to replace the transmission. It still sounds like a bearing to me.. possibly the input shaft bearing if that exists? I don't want to pull it apart quite yet if its still driving good. Any other suggestions are great .
Thanks!

Well, you got one other possibility. Try to find a local trannie shop that
will do a quick diagnosis by driving and listening to it. Dont let them
tear it down. If your crafty, you can get there opinion for free.

Yea I'd like to avoid going to a shop yet....I'd like to do the work myself as I am somewhat mechanically inclined. But I'll keep it in mind.... I still think it could be a bushing or bearing in the transmission that is wearing out ...maybe somewhere around the torque converter?

That sounds like the transmission pump. Does it sound the same from below?
I heard the same sound from mine when I bought it, knowing it would need a transaxle overhaul.
