Hey guys ive done the Royal purple Max ATF transmission fluid change on both on our Mazda 6 and ford fusion. 25000miles later its still shifting smooth like butter. Royal purple tech told me they have ran these cars for hundred thousands of miles with no problems. The stock fluid on my fusion shifted ok. Changed it at 5K miles with RP max ATF shifts like butter even compared with the stock fluid. Mazda 6 now has 78000miles still shifting like new. These cars transmission fluid are so easy to change i recommend doing them every 30K cause they get dirty pretty quickly.
