Hard parts and clutched might be difficult to find, but seals are readily available. https://skidim.com/drivetrain/transmissions/pcm-40-series-parts.html

Agree with the above on the damper plate. You might get relief by rasing the idle speed a smidge. Spec calls for 600 RPM IN GEAR and UNDERWAY

Start with any Dexron ATF and bumping the idle a bit and see where you end up. The leak needs to be addressed through.
Planning on getting the leak fixed the right way, thank for your feedback and advise on the noise. Replacing the seals is probably a good winter project and will live with a few drips until this fall.
