I’ve been researching what modern day ATF replacement to use for the original Type A, Suffix A (Mercedes-Benz Sheet 232.2) recommended by Mercedes for automatic transmission type K4A 025. The answer appears to be Dexron III, and definitely not to use synthetic or a synthetic blend.
Now where to purchase? My local O’Reilly auto parts has their branded premium ATF which is their replacement for Type A, Suffix A. When I called their technical support number, they said they don’t know if it meets Mercedes-Benz Sheet 232.2, and would not warranty this use.
Looking for recommendations of brands to use and where to purchase - I am in Michigan.
