Capacities

a Actual quantities will vary a few ounces based on applications. Always use the fluid level indicator for setting the proper level.
b 5.4L applications with in-tank coolers and OTA may require an additional few ounces.

MERCON ATF is being replaced by MERCON V ATF as a service fluid, per TSB 06-14-4..

CAUTION: Using a transmission fluid that indicates a dual usage MERCON and MERCON (R) V in a transmission application requiring MERCON (R), may cause transmission damage. Use of any fluid other than the recommended fluid may cause transmission damage.

Note:
- Refer to the dipstick and the Owner's Guide for the type of transmission fluid required. Some fluid labels may indicate dual usage such as MERCON (R) and MERCON (R) V. These dual-usage fluids are not to be used in transmissions that use only the MERCON (R) type fluid. These dual-usage fluids may be used in transmissions that require MERCON V use.
- Always use the fluid level indicator to check and set the proper level of the transmission fluid.

The above fluid capacities are approximate dry fill capacity and include fluid coolers and fluid cooler tubes. Fluid level indicator should be used to determine actual fluid requirement and fluid specifications. Check level at operating temperature. DO NOT OVERFILL.
The transmission fluid should be changed every 30,000 miles (48,000 km) regardless of normal or special operating conditions.
