Auto trans. fluid

Hey guys,

My 67 Dart has the 225/904 Combo. It has 81,700 orignal miles,and me and the PO think the trans has never had a fluid change.I wanted to know what fluid you think I should use? Do you think it would be ok if I went synthetic? I drive it everyday as my main mode of transportation,and thought the extra m.p.g and h.p increase might help! What do you think?
