Easy answer: Get it at the dealer and forget the aftermarket exists for transmission filters.
Chrysler has in the past (and as of '07 still did) specified different filters for different applications, which themselves sometimes use slightly different transmissions. The aftermarket, on the other hand, generally makes one blanket filter per transmission family. This can and does create situations where the "right" aftermarket filter ain't remotely right.
