Since when did fram market trans rebuild kits?

There is nothing magical about box kits for automatic transmissions. For a stock application in a Mopar, look for either Raybestos or Borg Warner Friction discs. As there are few gasket set manufacturers (despite whatever name is on the packaging) and anything that has a made in the US on it will be fine. If it is really old stock, then there is the possibility that the gaskets have shrunk, and the lip seals might be deformed. I don't know where you live, but if you're in the US, look for a trans-star parts outlet and or W.I.T. transmission parts. At least with these people, you are dealing with some one involved directly in the transmission industry, which may not be true with someone on bay. Shopping for the cheapest isn't always your best move
