Ford transmissions are designed for use in many different service environments and operating conditions. Each transmission has its own set of requirements for its fluid and each Motorcraft® Automatic Transmission Fluid (ATF) has specially formulated properties to meet those requirements.
MERCON® transmission fluids undergo extensive testing, both in the lab and in real-world conditions, to ensure they provide optimum performance and durability. MERCON® fluids are the only fluids approved for their recommended applications by Ford Motor Company.
The different MERCON® fluids are unique fluids formulated for specific applications. Their specifications DO NOT overlap and use of fluids other than specified may cause reduced functionality or transmission damage. Remember – there is no “one-size-fits-all” automatic transmission fluid!
