Presupposing you are capable of working on your own vehicle.
-Buy a new Subaru AT filter. Yes, these are different than oil filters that are usually listed.
-Buy 3 or 4 gallons of Dex III ATF. (Bang for the buck, I suggest Valvoline Maxlife purchased with a discount code from Advance Auto.)
-Buy new crush washer for the AT drain plug.
Pull AT drain plug, drain out fluid, approx 4 to 4.5 quarts. Remove old AT filter and replace. Drive around for awhile,make sure the car gets every gear P through D.
Drain and fill again as your schedule allows. Repeat.
Slowest and gentlest method, will end up with 90%+ fresh ATF when you are done.
Changing Automatic Transmission Fluid (is easy)
FYI: I changed out the (apparently) original ATF in KAyless at 100k. She is a happy wagon now.
2003 Outback wagon: "Kaylee". 146,000 and counting.
Basics: Quaker State Ultimate Durability 5W30, PureOne oil filter, Fram air filter, Valvoline Maxlife Dex/Merc ATF, Mobil 1 75W90, Michelin Primacy MXV4.
Mods: 2004 Forester XT shift knob, Fumoto oil drain valve, Phillips VisionPlus low beams, Phillips HIR1 high beam upgrade, Nokya Hyper Yellow 2500K fog lights.
Also: More rust than I care to think about.
