11 - 14.5 quarts depending on which tranny you have.
4 - 4.5 quarts for a pan drop.
ATF+4 will work with either the Chrysler or Toyota based transmissions. You can't go wrong with Amsoil ATF or any good synthetic that will exceed ATF+4 specs.
I think you have the aisin warner tranny, not a mopar tranny.
They were designed for dex3 but atf+4 has superceded that
recomendation, probably for dealer convinience (less oil stash)
Anyway, atf+4 will work good and so does dex3 in an aisin tranny.
