Hey Vince, I seen that also. It actually looks like the bottom of another E to me. But you are right, it could be a baby C. I can tell you it doesn't have the bottom drain plug, so I think it's an M-20? I will post the other trans pic's. I am hoping all of you experts chime in and keep chiming in to tell me the stamps, and numbers look good. I spent a lot of time collecting data.... Danny
