What transmission do I have? 72 Sierra Grande

They ALL seem to leak from one place or another, but that one looks pretty slimy. If it is just generally tired and leaky why not have it rebuilt instead of buying a new one? Unless you want to upgrade to a more modern overdrive transmission or something. One thing to note, the truck TH350s are different than the car TH350s, the truck versions have one or two more clutch packs than the car versions.

The transmission was rebuilt twice by the previous owner (my grandpa) back in the 90's, but it never fixed it. He has tried everything from new seals and gaskets to a full blown rebuild and it fixes it for a few months and then the leak progressively gets worse. I have a feeling that the metal is warped where the engine meets, but that doesn't seem to be the only location. I will take it in to a transmission specialist and see what they say, but I don't want to fix it again. I found a brand new factory tranny for $1400.

Thank you for the information on the differences between the car and truck though, I will definitely use that.
