    I have a few transmissions with various stamped numbers. How can I tell what year they are? One has E2 and a case vent. One has E2 and ratchet top vent. One has a ratchet top vent and only 121-35 stamped on it. The last one has C.C.C. stamped on it or it could be O.O.O. with ratchet top vent. Any help would be appreciated.

    Chauncy,
    Not sure what you are referring to by ratchet top vent. Do you mean the hollow screw? A picture of each case with markings is the best way to get them identified.
