Fluid Type Explained

The 2020 Ford Explorer, depending on its engine and drivetrain configuration, is predominantly equipped with the Ford 10R60 10-speed automatic transmission. This advanced transmission requires a very specific type of fluid to operate correctly and ensure its longevity: Ford MERCON ULV Automatic Transmission Fluid. ULV stands for "Ultra-Low Viscosity," and this fluid is specially formulated to reduce internal friction, improve fuel economy, and contribute to the transmission's overall efficiency.

Using any other type of automatic transmission fluid (ATF) in your 2020 Ford Explorer's 10R60 transmission can lead to severe operational issues, premature wear, and potentially catastrophic transmission failure. These transmissions are precisely engineered, and the delicate balance of friction modifiers, detergents, and anti-wear additives in MERCON ULV is critical for proper operation of its intricate clutch packs, valve body, and planetary gear sets. Always confirm the exact fluid specification in your owner's manual or with a certified Ford service center.

Service Procedure

When it comes to servicing the 10R60 transmission in your 2020 Ford Explorer, there are generally two methods: a drain and fill, or a full fluid exchange (also known as a flush).

• Drain & Fill: This procedure involves draining the fluid from the transmission pan and refilling it with new MERCON ULV fluid. While simpler and less expensive, it only replaces a portion of the total transmission fluid (approximately 6-7 quarts). A significant amount of the old fluid remains in the torque converter, valve body, and cooler lines. This method is often recommended for regular maintenance within the normal service interval. Multiple drain and fills over a shorter period can gradually replace more of the old fluid.

• Full Fluid Exchange (Flush): A full fluid exchange uses specialized equipment to completely remove all of the old transmission fluid and replace it with new fluid. This process involves disconnecting cooler lines and using a machine to pump new fluid through the system while simultaneously extracting the old fluid. This ensures that nearly 100% of the fluid is replaced, including the fluid in the torque converter and cooler lines. While more thorough, it
