It was not in 4WD. I have not tried to duplicate the sound while in 4WD.

That's a good sign, did you have any metal inside the differential after you took the third member out?

I do not know what you mean by "third member"?

There were no signs of damage and no metal shavings or pieces when I pulled the differential. There were no metal shavings on the magnet in the housing of any note and no fines in the bottom of the housing either.

I replaced the junk yard differential into my vehicle and had no change in the sound/vibration. I am now thinking it must be the transmission. I do not believe it would be the front differential as it is only engaged during 4WD isn't it?

Yep, I don't think it is the front differential either. It must be the transmission. I would try to service it first to see if you have any metal inside.
