Max ATF® is a synthetic, high performance, long life, multipurpose, automatic transmission fluid.

Max ATF® is recommended for all automatic transmissions requiring Ford Mercon® or GM Dexron® III transmission fluids.

Max ATF® is more oxidation stable than other transmission fluids and greatly resists breakdown from heat and loss of proper lubricity.

Max ATF® is fully compatible and can be mixed with other automatic transmission fluids; however, for the best results drain or flush current oil and then fill with Max ATF®.
