ATF in 12A procedure
 

I'm thinking about buying a 1st gen that's been sitting around for a couple of years. It ran when last started. But now, I'm told by the owner, that it won't start.

If the seals are frozen, how do I free them with the ATF? How much do I put in? HOw long do I leave it in there before starting it up? Anything else I should know since I've never done this before?
