I've shipped an 833 iron transmission with UPS about 15 years ago. It weighed 135 pounds and I think I charged $150 to make a crate and ship it. I shipped another one with Fastenal and just strapped it to a pallet and it only cost me about $60
I have heard Fastenal recently raised their rates though.
