What kind of transmission fluid does a 2004 Ford F250 take?

The typical answer is Mercon V transmission fluid for most 2004 Ford F-250s with automatic transmissions. If your truck has a manual transmission, use the gear oil specified in the owner's manual. The exact fluid depends on the transmission model (4R100 or 5R110W), so verify your specific setup before topping up or changing the fluid.


Two main automatic-transmission options for 2004


The following overview covers the automatic transmissions most commonly found in 2004 F-250 Super Duty models and the fluids they typically require.


Note: The exact specification can vary by production date and vehicle configuration. If in doubt, consult the owner's manual or the transmission tag for the precise specification.



  • 4R100 automatic (used in many early 2000s Super Duty trucks): Mercon V is commonly recommended for this transmission, though Ford documentation can vary by production date.

  • 5R110W automatic (introduced in the mid-2000s and used in some 2004 F-250s): Mercon V is typically recommended by Ford for this transmission as well.

  • Manual transmission (less common in 2004 F-250s): Use the gear oil specified by Ford, typically a GL-4 75W-90 fluid meeting the manual’s spec.


Conclusion for the list: If your F-250 is automatic, Mercon V is the standard guidance for the common transmissions in 2004 models; for a manual, refer to the manual for the exact GL-4 gear oil spec.


How to confirm the exact fluid for your truck


Because Ford published fluid specs can vary by production date and transmission model, use these steps to verify the correct fluid for your specific truck.



  1. Identify the transmission model: check the vehicle’s VIN, the transmission dipstick tag, or the build sheet/owner’s manual.

  2. Check the owner’s manual or Ford service literature for the fluid specification corresponding to that transmission.

  3. Only use the fluid that matches that specification; if in doubt, contact a Ford dealer or a qualified mechanic.


By following these steps, you can ensure you use the correct transmission fluid for your 2004 Ford F-250 and avoid potential shifting or hydraulic issues. Always adhere to the specified fluid and service intervals.


Summary


For most 2004 Ford F-250s with automatic transmissions, Mercon V is the recommended fluid, particularly for the common 4R100 and 5R110W transmissions. If you have a manual gearbox, use the gear oil specified in the owner's manual, typically GL-4 75W-90. Always verify the exact transmission model to confirm the correct fluid and service interval.

What kind of transmission fluid does a 6.0 take?


The correct transmission fluid for a 6.0L Powerstroke depends on the transmission type. Automatic transmissions with the 5R110 (TorqShift) require Motorcraft MERCON LV fluid (which replaced MERCON SP), while manual transmissions with the ZF S6-650 require MERCON V. It is crucial to use the specific fluid recommended for your vehicle's transmission to prevent shifting problems and damage. 
Automatic transmission (5R110 - TorqShift) 

  • Fluid: Motorcraft MERCON LV Automatic Transmission Fluid is the current, updated recommendation. It is a full synthetic replacement for the original MERCON SP. 
  • Why it's important: Using a generic fluid can lead to shifting issues like hard or sloppy shifts.

Manual transmission (ZF S6-650)
  • Fluid: Motorcraft MERCON V Automatic Transmission Fluid.
  • Why it's important: MERCON V is the specific fluid for the ZF S6-650 6-speed manual transmission and is also specified for the power steering system in some models. 

Important considerations
  • Always check your owner's manual for the exact specifications for your specific vehicle. 
  • When in doubt, using the Motorcraft brand fluid from a Ford dealership is the safest option, as it ensures compatibility and avoids potential shifting problems. 



What type of transmission fluid does a F250 take?


The correct Ford F-250 transmission fluid type depends on the year and model, but it is most commonly MERCON LV for newer models (around 2015 and newer) and MERCON V for many older models. It is crucial to check your owner's manual or the transmission dipstick to confirm the specific type needed, as using the wrong fluid can cause damage. Some older transmissions might use a different type altogether. 
Transmission fluid types by F-250 year range 

  • Newer F-250s (approx. 2015 and newer): Require MERCON LV (Low Viscosity) automatic transmission fluid. 
  • Older F-250s: Many models from before the mid-2010s typically use MERCON V automatic transmission fluid. 
  • Very old models: Some very early F-250s may have different requirements. For example, some transmissions before 1977 used Type F fluid, but this should NOT be used in transmissions that require MERCON fluids as it can cause severe performance problems. 

Important considerations
  • Check your owner's manual: This is the most reliable source for the exact type of fluid required for your vehicle. 
  • Look for the correct specification: In addition to a name like MERCON V or LV, check that the fluid meets Ford's specific requirements. 
  • Avoid mixing fluid types: Do not mix different types of transmission fluids, especially older fluids like Type F, with newer MERCON fluids. 
  • Use quality fluids: Choose a reputable brand and, where recommended, a full synthetic option to help extend the life of your transmission.

Is all ATF +4 full synthetic?


Yes, ATF+4 is a synthetic automatic transmission fluid that is licensed by Fiat Chrysler Automobiles (FCA) to meet specific performance standards for Chrysler, Dodge, and Jeep vehicles. It is engineered to provide better thermal stability, reduced wear, and consistent shifting compared to conventional fluids.
 

  • Composition: ATF+4 is a full-synthetic fluid designed to protect automatic transmissions in FCA (now Stellantis) vehicles. 
  • Licensing: The "ATF+4" designation is a registered trademark licensed by FCA, ensuring that products from different brands meet the same quality standards. 
  • Benefits: The synthetic formula offers superior performance over conventional fluids, including better protection against heat, oxidation, and wear, which extends transmission life. 
  • Usage: It is backward-serviceable, meaning it can be used in older transmissions that require ATF+, ATF+2, or ATF+3 fluids, and it is the standard for many newer models as well.
