Like I said, if it meets the needs, it's ok. Personally, I use the cheapest fluid that meets the requirements. You should be using ATF +4 I believe. Amsoil Universal ATF is supposed to work fine as a substitute(according to Amsoil and at least one poster here), I don't know about any other brands. All I know for sure is ATF +4 is especially formulated for late model Chrysler transmissions like yours. IMO it's best to use what the manufacturer recommends. <img src="/forums/images/graemlins/cheers.gif" alt="" />
