A Ford Explorer Owner's Guide to the 2012-2019 Transmission Filter Kit
Keep your Explorer's 6-speed automatic shifting smoothly by understanding its unique transmission filter.
- The transmission filter on 2012-2019 Explorers is internal and not meant for routine replacement.
- Prevent filter clogs by performing regular fluid drain-and-fills every 30,000-50,000 miles.
- Always use transmission fluid that meets the Ford Mercon LV specification to avoid damage.
- Symptoms like harsh shifting, whining noises, or a burning smell signal a problem that needs immediate attention.
Is Your Explorer's Transmission Acting Up?
The automatic transmission in the 2012-2019 Ford Explorer has an internal filter that isn't meant to be changed during routine maintenance. Ford's design means the filter should only be replaced during a major transmission rebuild. Because of this, keeping the transmission fluid clean is the most important thing you can do. If the fluid gets too dirty, the filter can become clogged, leading to serious problems. Ignoring these symptoms can lead to complete transmission failure.

A restricted filter starves the transmission of the fluid it needs to work correctly. Look out for these warning signs:
- Delayed or Harsh Shifting: The vehicle may hesitate, jerk, or shift hard when changing gears. This happens because the clogged filter restricts fluid flow.
- Whining or Grinding Noises: Unusual noises from the transmission area can indicate the fluid pump is struggling to pull fluid through a blocked filter.
- Transmission Overheating: A blocked filter can cause the transmission to run hotter than normal, which can damage seals and internal parts. You might notice a burning smell.
- Sluggish Acceleration: If the vehicle feels slow or lacks power, it could be due to poor fluid circulation in the transmission.
- Fluid Leaks: Increased pressure from a blockage can sometimes cause fluid to leak from gaskets or seals.
A Note on Serviceability
For the 6F35 and 6F50/55 transmissions in these Explorers, the main filter is not in the pan. It is located between the two halves of the transmission case. This makes replacement a very difficult job that requires removing and disassembling the entire transmission. Therefore, what is often sold as a "filter kit" for these models may be a pan gasket and a new drain plug, or in some cases, an incorrect part. Always verify the part's function before purchasing. The best prevention is performing regular transmission fluid drain-and-fills every 30,000 to 50,000 miles to prolong the life of the internal filter.
Choosing the Right Parts for a Fluid Service
Since you can't easily change the filter, focusing on high-quality fluid is key. If you are dropping the pan for any reason, using a quality gasket is also important. Here’s a look at the brands.
Brand Quality Tiers
- OEM - Motorcraft: This is the original Ford part. For transmission components, sticking with Motorcraft is almost always the safest bet. It guarantees perfect fit and function as designed by the engineers. Given the sensitivity of modern transmissions, using the specified Motorcraft Mercon LV fluid is highly recommended by mechanics and owners.
- Premium Aftermarket - Wix: Wix is a well-respected brand known for making high-quality filters that often meet or exceed OEM standards. If a serviceable aftermarket filter solution is available and you choose to use it, Wix is a reliable choice.
- Standard Aftermarket - ATP & Premium Guard: These brands provide a cost-effective alternative. ATP is noted by some mechanics for providing good quality gaskets. They are generally considered acceptable for drivers on a budget, but for a critical component like the transmission, the small savings may not be worth the potential risk compared to OEM.
Pro Tip: Drain and Fill, Don't Flush
Many owners and mechanics advise against a high-pressure transmission "flush" on higher-mileage vehicles. A simple drain-and-fill procedure is safer. This process typically replaces about 4-5 quarts of the old fluid. Performing this service a few times over a short period can replace most of the old, dirty fluid 🎬 Watch: Professional fluid exchange procedure for 6F50/55 transmissions without risking damage.

Frequently Asked Questions
Do I really need to change my transmission filter?
No, not as regular maintenance. The main filter in the 2012-2019 Explorer's 6F35/6F50/55 transmission is considered a non-serviceable part for the life of the vehicle. It should only be replaced if the transmission is being completely rebuilt. Focus on changing the fluid regularly instead.
What kind of transmission fluid should I use?
You must use a fluid that meets Ford's Mercon LV specification. Using the wrong type of fluid can cause shifting problems and damage the transmission. Sticking with the genuine Motorcraft Mercon LV fluid is the recommended choice.
Are there any recalls for the transmission on these Explorers?
While there have been recalls for the 2011-2017 Explorer models, they were primarily for issues like a rear suspension toe link and transmission control software that could cause unintended downshifts, not for the filter itself. Other recalls for newer models (2020-2022) involved a rear axle bolt that could cause the vehicle to roll away while in park. Always check with the NHTSA website for your specific vehicle's VIN.
How hard is a transmission fluid drain-and-fill?
For a DIYer with some experience, it's moderately easy. The process involves removing an underbody shield, opening a drain plug, and then refilling the correct amount of fluid through a fill port on top of the transmission, which can be hard to access. The fluid level must be checked carefully when the transmission is at operating temperature. It does not require dropping the transmission pan.
