Brass or Dacron transmission filter

Dacron filters first came as standard equipment on the Torqueflite in 1964. That's the type to use unless you are installing an in-line external filter of some kind in which case you can use a brass screen in the trans. I like genuine Chrysler filters better than aftermarket. Save yourself a bunch of trouble and use the one and only worthwhile pan gasket: Chrysler 2464 324AB, which is a rigid double-seal reusable design that will seal. Fluid, see here.
