So as an update - I dropped the car off at the trans shop for a once over. Most likely going to have them do a full refresh on it. There was a fair amount of brass? I believe in the trans pan during the last fluid change when I added the new converter back in April... Hopefully its just some worn parts and nothing any more major.
Trans guy mentioned wheel balance or bent axle(s). I dont think this would cause a harmonic type of vibration but what do I know. Although my dads mazda MPV had a bent axle in the rear and you felt that from 35mph and up, certainly wasnt harmonic or change with load.
