The 2008 Ford Explorer typically requires Mercon V automatic transmission fluid for its 5-speed automatic transmission (the 5R55S family).
In practice, Ford's manuals for that year recommend Mercon V to maintain proper shifting and lubrication. Using the wrong fluid can cause shifting problems or transmission wear over time, so it’s important to verify the exact specification for your VIN by checking the owner’s manual or consulting a Ford dealer.
Transmission type and fluid requirement
To understand the fluid requirement, it helps to know the standard transmission in the 2008 Explorer and how Ford specifies the fluid for that unit.
What fluid to use
Before listing the fluid, note that Ford's service guidelines for the 2008 Explorer specify Mercon V as the correct ATF for its automatic transmission.
The following fluid option is appropriate for the 2008 Ford Explorer's automatic transmission.
- Motorcraft Mercon V Automatic Transmission Fluid (or equivalent Mercon V)
Always consult your owner's manual or your dealer to confirm the correct specification for your specific vehicle, especially if it has any atypical features or has had non-standard repairs.
Maintenance tips and checks
Keeping the transmission fluid in good condition helps ensure smooth operation and longevity. Here are basic tips related to fluid changes and level checks.
- Check the owner's manual for recommended service intervals; many Ford dealers suggest changing ATF at around 60,000 miles or as needed based on driving conditions.
- Use the engine warmed up, the vehicle on a level surface, and with the transmission in Park to check the ATF level using the dipstick if equipped.
- When replacing fluid, ensure the pan is cleaned and the filter is inspected if accessible; use the correct OEM or equivalent Mercon V fluid.
Note: Some later Ford guidelines may reference different fluid standards for other model years or transmissions; always verify with official Ford documentation for your VIN.
Summary
For a 2008 Ford Explorer, Mercon V automatic transmission fluid is the standard specification for the vehicle's 5-speed automatic transmission (5R55S family).
