Using a transmission fluid that indicates a dual usage MERCON and MERCON V in a transmission application requiring MERCON, may cause internal transmission damage. The use of any fluid other than the recommended fluid may cause transmission damage. Refer to the transmission fluid level indicator and the Owner's Guide for the type of transmission fluid required. Some fluid labels may indicate dual usage such as MERCON and MERCON V. These dual-usage fluids are not to be used in transmissions that use only the MERCON type fluid. These dual-usage fluids may be used in transmissions that require MERCON V use.

Use Motorcraft MERCON V Multi-Purpose (ATF) Transmission Fluid XT-5-QM or equivalent to ford specification - MERCON V

MERCON(R) Automatic Transmission Fluid is being replaced by MERCON(R) V as a service fluid, per TSB 06-14-4.
