I have some Mobil 3309 from a Mitsubishi Fuso that is now gone. I still have a 99 Saturn SL2 Automatic and a 99 Subaru Forester Auto. I looked at the 3309 Spec and it seems to line up with the old Dex3 spec pretty close, cSt @100C is 7.1. The Mobil site indicates that it's compatible with Toyota T3 or T4, whatever that means. I'm thinking drain and refil on the Saturn should be fine. Any reason not too?
