What transmission is this? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I recently purchased an engine and transmission out of what the PO thought was a small 1972 1 ton fire truck. He said the truck ran fine and shifted great. I know it is a 4 speed granny gear but dont know if it was ever used in a half ton or 3/4 ton. Any input is appreciated.

SM465 tranny. Real common in one tons used from around 1968 to 1991. Not in 1/2 tons that I know of mainly 3/4 and 1 ton
