I believe there was an "Eureka!" posting on this subject in the not too distant past. That posting talked about the friction materials that the bands and clutches have. The correct fluid will depend upon the materials. Different materials, different fluids. Sorry, I do not recall anymore about this. None of my Packards have Ultramatic transmissions so I did not pay a lot of attention to the posting except I thought it was a good answer to the what fluid to use question.
