Fluid Type Explained

The 2024 Ford Explorer uses a sophisticated 10-speed automatic transmission, either the 10R60 for models with the 2.3L EcoBoost engine or the heavier-duty 10R80 for models equipped with the 3.0L EcoBoost or 3.3L Hybrid powertrain. Both transmissions require a very specific fluid to function correctly: Motorcraft MERCON® ULV (Ultra-Low Viscosity).

This is not a traditional ATF. MERCON® ULV is a fully synthetic, extremely thin fluid developed specifically for Ford's latest generation of transmissions. Its primary benefits are improved fuel efficiency (due to lower rotational friction) and enhanced shifting performance across a wide range of temperatures. Using any other type of fluid, including older MERCON® formulations like LV, V, or SP, will lead to poor shifting, accelerated wear, and eventual transmission failure. Always insist on MERCON® ULV to ensure the longevity of your Explorer's transmission.

Service Procedure

Servicing the 10R60/10R80 transmission can be done in two ways: a traditional "drain and fill" or a "full fluid exchange."

• Drain and Fill: This is the more common and straightforward method. It involves removing the transmission drain plug, allowing 9-10 quarts of fluid to drain out, and then refilling with fresh MERCON® ULV. This method is simpler and less expensive, but it leaves a significant amount of old, degraded fluid in the torque converter and cooler lines.

• Full Fluid Exchange: A full exchange uses a specialized machine to pump out all of the old fluid while simultaneously refilling the transmission with new fluid. This ensures that nearly 100% of the old fluid is replaced. While more costly, a full fluid exchange is the superior method for long-term transmission health, as it removes more contaminants and completely refreshes the fluid.

For the 2024 Explorer, a full fluid exchange is highly recommended, especially if you are towing or driving in severe conditions. Due to the complexity of the 10-speed transmission and the specific fluid level checking procedure, this service is best left to a professional technician.

Service Interval

Ford's official recommendation for transmission service under "normal" driving conditions is a lengthy 150,000 miles. However, what constitutes "normal" driving is often not reflective of real-world conditions.

• Normal Duty: If you primarily drive on the highway in a temperate climate with minimal stop-and-go traffic, the 150,000-mile interval may be adequate. However, we recommend a more conservative interval of 100,000 miles for peace of mind.

• Severe Duty: Most drivers fall into the "severe duty" category without realizing it. This includes:

  • Towing trailers
  • Frequent short trips (under 10 miles)
  • Driving in heavy city traffic
  • Driving in very hot or very cold climates
  • Driving on dusty or unpaved roads

If any of these conditions apply to you, the transmission service interval should be much shorter. For severe duty applications, we strongly recommend a transmission service every 30,000 to 50,000 miles to prevent premature wear and tear.

Common Transmission Problems

The Ford 10R60 and 10R80 are generally robust transmissions, but some common issues have been reported. Many of these are software-related and can be addressed with a trip to the dealer for a powertrain control module (PCM) reflash.

• Harsh or Jerky Shifting: The most common complaint is rough or erratic shifting, especially in the lower gears. This can feel like a "clunk" or a sudden jolt when the transmission shifts. Often, this can be resolved with a software update.

• Delayed Engagement: Some owners report a noticeable delay when shifting from Park to Drive or Reverse. This is another issue that can often be corrected with a PCM update.

• Busy" Shifting: With 10 gears to choose from, the transmission can sometimes feel "busy," frequently shifting up and down. While this is often normal behavior as the transmission seeks the most efficient gear, it can be unnerving to some drivers.

If you experience any of these symptoms, it's important to have your vehicle inspected by a qualified technician. In many cases, a simple software update is all that's needed. However, if the fluid is burnt or the transmission is showing signs of mechanical wear, a more involved repair may be necessary.
