What kind of transmission fluid does a 2017 Ford F350 take?
The 2017 Ford F-350 with the 6R140 TorqShift automatic transmission uses Ford Mercon SP automatic transmission fluid (ATF). This article explains the official spec, compatibility notes, and practical servicing guidance.
Fluid specification and compatibility
Key details you should know about the correct ATF for the 2017 F-350 are listed below.
- Recommended fluid: Ford Mercon SP automatic transmission fluid (ATF).
- Compatibility: Suitable for the 6R140 TorqShift automatic transmissions used in the 2017 F-350, including both gasoline and diesel engines that pair with this transmission.
- What to avoid: Do not use Dexron VI, Dexron II, or Mercon V unless Ford explicitly approves them for your specific application.
- Service capacity: A typical pan drain and fill for this transmission is roughly 12–14 quarts to complete the process, though exact capacity varies with the vehicle configuration and whether a full flush is performed.
Using the correct Mercon SP ATF and following proper service steps helps maintain shifting performance and transmission longevity. If in doubt, consult the owner's manual or a Ford dealer for the exact specification for your truck.
In short, the 2017 F-350’s transmission requires Mercon SP ATF, and sticking to Ford-approved fluids is the best way to ensure compatibility and performance.
Why this matters and practical tips
Choosing the right fluid is more than a label—it's about protecting clutches, seals, and hydraulic circuits inside the 6R140. Ford’s Mercon SP formulation is designed to meet the shifting and wear characteristics of this transmission under a range of temperatures and workloads.
- Do not mix different ATF types. If you’re topping up and unsure, use the same specification or consult a professional.
- Check the dipstick and manual for exact fill levels and service intervals. Some owners perform periodic checks during routine maintenance.
- Consider using a high-quality Mercon SP that meets Ford's specification rather than off-brand fluids to avoid shifting or longevity issues.
Following these practices helps ensure smooth shifts and reduces the risk of transmission wear over time.
Summary
For a 2017 Ford F-350 equipped with the 6R140 automatic transmission, Ford’s recommended fluid is Mercon SP ATF. Use fluids that meet Ford’s Mercon SP spec, avoid Dexron-type fluids unless explicitly approved, and follow proper service procedures to maintain transmission performance and durability. When in doubt, consult the owner’s manual or a Ford dealer for confirmation specific to your truck.

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.
