I want to replace the transmission fluid in my 20004 Outlander before winter gets here. The manual calls for Genuine Mitsubishi Automatic Transmission Fluid AFT SP-III Parts No: MZ320200. I assume everyone doesn't run to the dealer to buy their fluid. What can I use that I can buy at a local parts store, like AutoZone? Is there a certain classification that I should look for?
Thanks!

 

Any ATF that meets the SP-III spec will work from your local parts store - it isn't a special fluid.

AMSOIL has split their ATF products into Signature Series and Original Equipment (OE) lines.
OE is for people/shops looking for a top quality ATF at a reasonable price. Signature is the best ATF AMSOIL has and is what I install.

You're looking at ATF or OTF in the red labelled bottles:
