Transmission ID, need help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok. Complete newbie here. I’m looking at a continuous leak of trans fluid from a seal and the pan as well. While checking it out I’m thinking, hey, something's missing, but being the newb that I am it took me awhile. There’s no bell housing.

How do I go about IDing the transmission? Everything tells me to look for numbers, but I’m not seeing any except on the pan and those are talking about possible patent numbers (?). Where do they like to hide? I’ll include what pics I have.

Go easy on me! Like I said, I’m learning as I go.

If we had a complete picture of the pan we could tell by the shape of it.

Your not missing the bellhousing your just missing the cover that goes over the Auto trans converter , trans id is done by the shape of the trans pan.
