2016 Ford Explorer Transmission Problems – Troubleshooting And Repair

ByRobert Lozano

The 2016 Ford Explorer is a popular SUV, but owners often report issues like hard shifting, shuddering, or complete gear failure. This guide breaks down common symptoms, root causes, and actionable steps to help you diagnose and manage these mechanical frustrations effectively.

You bought your Ford Explorer because you needed a reliable workhorse for family road trips, grocery runs, and perhaps the occasional light trail. It is a fantastic vehicle until you feel that unsettling slip or hear a clunk during a gear change. Dealing with 2016 Ford Explorer transmission problems can feel overwhelming, but understanding the mechanics behind the shift is your first step toward a solution.

Whether you are a seasoned DIY mechanic or just someone who wants to avoid getting swindled at the local shop, you have come to the right place. We will walk through the diagnostic process, common red flags, and the difference between a simple fluid service and a full transmission rebuild. Let’s get your SUV back on the road with confidence.

Understanding 2016 Ford Explorer Transmission Problems

The 2016 model year utilizes a 6F50 or 6F55 six-speed automatic transmission. While these units are generally robust, they are susceptible to specific failures as the mileage climbs higher.

The most common complaints involve harsh 1-2 or 2-3 shifts and an occasional delay when engaging “Drive” or “Reverse.” If your vehicle hesitates before moving, it is often a sign of hydraulic pressure loss or internal wear. Recognizing these 2016 Ford Explorer transmission problems early can save you from a total breakdown on the highway.

Always start with the basics. Check your transmission fluid levels and condition before assuming the worst. If the fluid looks dark, smells burnt, or contains metal shavings, you are likely looking at mechanical wear inside the transmission housing.

Common Symptoms and Diagnostic Steps

Before you start pulling parts, you need to listen to what your vehicle is telling you. A transmission is a complex system of gears, clutches, and sensors that rely on precise fluid pressure.

Recognizing the Warning Signs

  • Delayed Engagement: A noticeable pause between shifting into gear and the vehicle actually moving.
  • Slipping Gears: The engine RPMs climb, but the vehicle does not accelerate accordingly.
  • Hard Shifting: Feeling a distinct “thump” or jolt when the car transitions between gears.
  • Transmission Warning Light: A dedicated icon on your dashboard indicating a fault in the transmission control module (TCM).

Performing a Preliminary Inspection

If you are comfortable under the hood, start by checking for external leaks. Look for red fluid spots on your driveway, specifically near the bell housing or cooler lines.

Next, use an OBD-II scanner to check for stored trouble codes. Even if the check engine light is not on, the TCM might have “pending codes” that point to a specific solenoid or sensor failure. These codes are invaluable for narrowing down whether the issue is electronic or mechanical.

The Role of Fluid and Cooling Systems

Many transmission issues are actually cooling or lubrication problems in disguise. Automatic transmissions generate immense heat, and the 2016 Explorer relies on a cooler to keep that heat in check.

Why Fluid Quality Matters

Old or contaminated fluid loses its ability to lubricate internal components and maintain hydraulic pressure. If you have exceeded 60,000 miles without a fluid exchange, you are pushing your luck. Using the manufacturer-recommended Mercon LV fluid is non-negotiable for these specific transmissions.

Managing Heat for Off-Roaders

If you take your Explorer on sandy trails or steep inclines, you are stressing the transmission significantly. Consider installing an auxiliary transmission cooler. This simple modification can drastically extend the lifespan of your transmission by preventing fluid breakdown during high-load scenarios.

When to Attempt DIY Repairs

As an enthusiast, you might want to tackle some of the work yourself. Some issues are manageable, while others require specialized equipment that belongs in a professional shop.

What You Can Fix at Home

  • Fluid and Filter Change: A messy but straightforward job that can resolve minor shifting sluggishness.
  • Transmission Mounts: If you feel a clunk during acceleration, check your mounts. A broken mount allows the transmission to shift under load, mimicking internal damage.
  • External Sensor Replacement: If your scan tool identifies a faulty speed sensor, this is often an accessible bolt-on fix.

When to Call a Professional

If you suspect internal clutch pack failure or a broken torque converter, you need a professional. Rebuilding a 6F50 requires specialized knowledge, specific torque sequences, and a clean-room environment. Trying to rebuild this yourself without proper training usually leads to a second, more expensive failure.

Prevention Strategies for Longevity

The best way to deal with transmission issues is to prevent them from starting. Your maintenance schedule is your best defense against premature failure. Change your fluid every 30,000 to 50,000 miles. Do not fall for the “lifetime fluid” marketing myth; no fluid is designed to last forever under the stress of daily driving. Regular changes remove microscopic debris that would otherwise act like sandpaper on your internal gears.

Additionally, be mindful of your driving habits. Avoid aggressive “neutral drops” or shifting into reverse before the vehicle has come to a complete stop. These habits put unnecessary strain on the internal planetary gears.

Frequently Asked Questions About 2016 Ford Explorer Transmission Problems

Is a transmission flush better than a drain and fill?

For older, high-mileage vehicles, a simple drain and fill is usually safer. High-pressure flushes can sometimes dislodge sediment, causing it to clog up small hydraulic passages within the valve body.

What if my transmission is slipping only when cold?

This is often a sign of fluid that has become too viscous or a failing internal seal. When the fluid warms up, it expands and seals better, which is why the problem seems to disappear after driving for a few miles.

Can I upgrade my transmission to be more durable?

While you cannot easily swap in a different model, you can improve durability by installing a high-quality external cooler and using a synthetic transmission fluid with better heat resistance. These small steps keep operating temperatures in the “green zone.”

How much does a transmission replacement cost?

Costs vary widely based on your location and whether you choose a remanufactured unit or a used one from a salvage yard. Expect to pay anywhere from $2,500 to $4,500 for a professional swap, including parts and labor.

Final Thoughts for the Road

Owning a 2016 Ford Explorer should be about the freedom of the open road, not the stress of a mechanical breakdown. By staying proactive with your fluid changes and listening to your vehicle’s cues, you can often mitigate the most common transmission issues before they become catastrophic.

If you do encounter issues, take a breath, use your diagnostic tools, and assess the situation logically. Whether you choose to tackle the repair in your garage or bring it to a trusted expert, having the right information is half the battle. Stay safe, keep your maintenance up to date, and enjoy the drive!
