The guy I bought my car off of (1967 Plymouth Fury Sport) said that the trans was leaking fluid. He gave me the seal to fix it (Part#03878447) but he didn't tell me what the seal went to. After some searching I found that it can either be the selector shaft seal or the kickdown seal. What is the best way to replace these seals? I plan on replacing the pan gasket and filters and I'd like to replace this seal while I'm at it. Any help would be appreciated. I'm assuming it's on the left side of the trans.
