$#@# leaking trans pan.

727 Pan: 5211 8780AD
727 Gasket: 2464 324AB (not 100% sure this is the rigid double-seal reusable design, but it is the latest p/n from Chrysler and costs exactly the same as the rigid double-seal reusable 904 gasket listed above, so odds are pretty good)

Doughnut magnet by itself in case they've decided to quit packaging it with the pan: 3681 601
