Mike,
I have not been on the forum in a week due to work, but saw this thread this evening.
I have listened to the video's and have never heard that sound come from a gm transmission or torque converter.
I did hear what sounded like an exhaust leak or air pump pulse leak.
The clicking noise I have heard on my ford. It was a blown catalitic converter.
I did hear the same click on my wifes Buick LeSabre and it was a loose heat shield.
I suspect from your e-mail that you think it may be the torque converter because it changes the noise when the torque converter unlocks. It could be because it frees up some rpm, unloading the drivetrain slightly.
Based on the videos, I am pretty sure it is not:
The trans pump
The torque converter
The internals of the trans.
The converter sold to you was hand built, and of first quality. Does that mean it is not possible to be defective? Of course not. It was built by a human, and he could have had a bad day.
If you are confident that it is defective, remove it, ship it back (I will provide a ship to address). If it is defective, it will be replaced, and shipped back to you at my expense (return shipping). If it is determined not to be defective, it will be reassembled, rewelded, rebalanced, repainted, and shipped back to you, again at my expense.
There is a 1 year warrantee from the date stamped in the converter, so you are covered either way.
* 1 thing I wanted to add:
In 1996, GM used a PWM pump. This is a Pulse Width Modulated pump. The PWM solenoid is designed to rapidly pulse the lock up on, off, on, off very quickly. It is very common for a PWM solenoid to fall out of range and cause lockup chattering.

Thanks for the response Pete. I'll continue to do some checking to try and pin point the noise further. All of this has narrowed it down some anyway.

Thanks a bunch!
I sent him a PM with this thread link earlier this evening. He's a busy man but has always responded....it just takes a while sometimes.
Can this cause any damage if I continue to drive the car normally? I'm out of town with the car and I need to go home tomorrow, about 80 miles or so.

Anytime something is rattling it could break and send crap through the fluid, clog up the passages and overheat the tranny. What may be a $300 converter can turn into a $1000 tranny fix.
