Kick down servo pin?

I'm no trans expert, but I think he's talking about the pivot pin for the low/reverse lever. The pin has an "O" ring on it that seals it.to remove the pin, you take the pan off. Then the tail housing has to come off. It retains the pin. This was leaking on my 64 Sport Fury. Took forever to find it. Easy fix. Might want him to change the 2 seals on the shifter pivot shaft while he's in there.
