This will unload the flexplate and if you then start the motor the noise should be gone unless the flexplate is hanging together by a thread.

Have you experienced this type of failure yourself in the past? Your Theory makes sense in my case, I have the AT, just replaced the Hub to the Harmonic Balancer, remanufactured the TH 400 and installed a new Torque Converter. Why not a Flexplate while I am at it?
Here is what happened to me: I drove over an Asphalt Drive way at a friend's new home. The Driveway did not have any cement under it to make the Asphalt flat. A tree root grew under the Asphalt raising the Driveway, I could never have expected this to happen, for it was my first time there. The Accident Broke the drive train and the Trans. lifted up while the Vehicle was moving forward. My Vehicle has been off the roar for close to 3 years fixing it. The Heads are just Remanufactured.
