Shipping Transmission
Pretty much #1 from the link
"Remove your transmission from the car and visit your local Wal*Mart-type department store. Purchase a 45 gallon Sterilite or Rubbermaid-type container like the one pictured above. You will also need plenty of packaging tape and material (cardboard, blankets, pillows, etc) if you don't already have them. (NOTE: Corvette, Viper and all TR-6060 transmissions require a 50 gallon container. Any container over 50 gallon will be charged a $50+ oversize fee by UPS.)"
Hope this helps
you might find a trans container at a dealer they would give/sell you
be interesting to hear from vendors how they do it-not cheap though
