Ok, so here is the situation. I have a 1982 300SD with a bad B2 piston. I know its bad, I had the "classic symptoms", took it apart, and the piston came out in pieces, several of them actually. I have a new piston ready to go in, I have the new plastic ring to replace the old metal one, new orange O ring to replace the old one, a bunch of fresh new tranny fluid ready to go in. This is a 722.303 transmission. So, here is my question, in order to get to the old metal ring which I have been hearing is very important to replace, there is a seal of some sort that goes between the metal ring and the flat part of the piston itself. I guess I missed seeing it in any of the pictures I have seen of this repair being done, and there was no mention of it made on any of the sites I have seen. This little seal is a bear to get out, and I have no idea what the part number is to replace it because it didn't come out in one piece. Does anybody have any idea what the Mercedes part number is for this little rubber seal? I'm going to need to get to the dealer to get it, and they don't know what I'm talking about. I suspect that they would rather sell me a new tranny and charge me labor for that job than sell me the parts I need. Any help would be greatly appreciated.
