Long time lurker, first time poster. A lot of great information this site, wish I could get a better handle on the search function. Any way, my daughter bought a 2003 Saturn Vue, 3.0l w/5speed automatic and naturally there is no owners maunal. I have been trying to identify which type of atf is used in the tranny. I have read T-IV, Dexron III-H and just plain ole Dexron III and so on and so on. JUST what atf does this thing use? I want to be sure it is the correct fluid since these Saturn's seem to have a terrible record concerning the transmissions. Would prefer a good OTC synthetic.
