What type of transmission fluid for a 2006 Subaru Forester?

For a 2006 Subaru Forester, you should use Subaru's own ATF (Automatic Transmission Fluid) or an equivalent high-quality fluid that meets the specifications for Subaru's automatic transmissions. Typically, this would be Subaru's ATF-HP or a compatible fluid that meets the JASO 1A standard. Always check your owner's manual for specific recommendations and ensure the fluid is suitable for your transmission type.
