To understand why and how to maintain it, here is a fuller explanation: the model’s automatic transmission from that era is designed to use Mercon V, Ford’s recommended specification for many of its 5-speed units. Using the correct fluid helps ensure smooth shifting, proper lubrication, and long-term reliability. If you’re ever unsure, consult the owner’s manual or contact a Ford dealer for the most up-to-date guidance.
Fluid specification and compatibility
Key compatibility notes for purchasing and replacing transmission fluid on this model:
- Use Mercon V automatic transmission fluid as the standard specification for the 2005 Ford Five Hundred’s automatic transmission.
- Genuine Ford Mercon V or an equivalent fluid that meets Ford’s Mercon V specification should be selected for top-offs and full fluid changes.
- Avoid using non-Ford Dexron fluids, as they may not provide the correct lubrication and could affect shifting and longevity. If you’re uncertain, consult your manual or a dealer before mixing fluids.
- If Mercon V is not readily available, check with a Ford dealer or service technician for approved alternatives or guidance on a temporary substitute.
In short, following Ford’s Mercon V guidance is the best practice for the 2005 Five Hundred, helping ensure reliable shifts and cooling within the transmission. For any exceptions or updates, refer to the vehicle’s official documentation or your local dealership.
Maintenance tips and how to check the level
Before checking or adding fluid, make sure you follow proper safety and procedure steps to avoid overfilling or creating leaks:
- Drive the car for a few miles to bring the transmission up to normal operating temperature.
- With the engine running and the transmission in Park on a level surface, locate and read the dipstick in the transmission area.
- If the fluid level is below the Full mark, add Mercon V in small increments using a clean funnel, then recheck the level.
- Do not overfill; stop when the level is at the Full mark on the dipstick.
- If the transmission fluid appears dark, milky, or has an unusual odor, it’s a sign to schedule a service or a fluid change with a professional.
- Consider a professional flush or service if the vehicle has shifting issues or high mileage, following the guidance in your owner's manual.
Always use clean, compatible fluid and tools, and watch for any leaks around the transmission pan or cooler lines after a change. When in doubt, consult a qualified technician.
Summary

Use genuine Ford Mercon V or an approved equivalent, and follow proper maintenance procedures to maintain smooth shifting and long transmission life.
