We don't stock a reviewed fluid for this spec yet. Search the confirmed standard on Amazon — it's the safest way to land on the right ATF. Pouring the wrong fluid is one of the few mistakes that can actually damage a modern transmission, so match the spec exactly.

Spec confirmed against two independent sources — never changed by what an affiliate link pays us. ATF, CVT fluid, DCT fluid, and manual- transmission fluid are not interchangeable, so match the exact spec rather than a close-sounding number. Your owner's manual is always the final word.
