If you want to go to the dealership and try and get the trans pan that DVW is talking about I think this is a part # that will work. 52118780AD with gasket 02464324AC. These #'s are for a 46RE but I am almost positive it shares the same shape as the 727/518 trans. But like Mr P-Body said, junkyard will probably be easier and cheaper than going the dealership route.
