engine/trans vibration

crackedback said

Flexplate/converter balance issue, offset in crank. Driveshaft.

Does it vibrate in park at higher RPM?

Have to test to elimate what isn't causing the issue.

It has a slight vibration in park at all RPM, the annoying cyclical vibration is most prevalent in 3rd gear at 1500-1800 rpm, even sitting on jack stands with drive shaft disconnected.
