My two cents worth: Be sure if you go UPS it is packed in a sturdy box with solid bottom such as a piece of 1/4" plywood with tranny cushioned good on plywood and strapped to wood with fiber glass tape. Be sure there is an over weight STICKER on BOX. Over 80 lb. is considered overweight as I remember.
I went through a 6 month claim adjustment with auto recycler over a tranny in a plain cardboard box that somebody dropped before I got it (maybe UPS) as differential case was hanging out of box and it was cracked and two teeth were busted off 1-2-reverse slider and 1 tooth off reverse idler.
I finally got another tranny which I also had to rebuild for other problems and even though I got to keep original busted up I had to end up welding differential case, replacing 1-2-R slider and reverse idler gear. Cost of parts and welding was almost as much as I paid for first tranny so I didn't really get two for the price of one.
