How do I validate 1954 Clipper Deluxe transmission

Hello,
New to site and new to Packard ownership. Just brought home a 1954 Clipper Deluxe and need to look into transmission. I have read various articles and it seems there are 2-3 possible transmissions:
1) Ultramatic
2) Gear Start Ultramatic
3) Twin Ultramatic (conflicting info, some say it was in late 1954 Packards)

How can I validate what transmission I have?
Thanks
Jim
