Common 2019 Ford Explorer transmission problems and Symptoms
Identifying the early warning signs of a failing gearbox is the first step toward a successful repair. Most owners of this specific model year report issues with the 6-speed automatic transmission, which can manifest in several distinct ways. Recognizing these audible and physical cues is vital for any proactive car owner.
Harsh Shifting and “Gear Hunting”
One of the most frequent 2019 Ford Explorer transmission problems involves the vehicle struggling to find the right gear. You might feel a hard “clunk” when the car shifts from second to third gear, or notice the engine revving high without a corresponding increase in speed. This “hunting” behavior often points to a failing shift solenoid or a software calibration issue within the Powertrain Control Module (PCM).
Delayed Engagement and Hesitation
If you shift from Park to Drive and notice a three-second delay before the vehicle moves, you are experiencing delayed engagement. This symptom often suggests that the internal seals are beginning to fail or that the transmission fluid pressure is dangerously low. In many cases, this is the precursor to a total transmission failure if ignored during the early stages.
Transmission Shudder and Vibration
Do you feel a sensation like you are driving over rumble strips even on a smooth highway? This is often referred to as “torque converter shudder.” It occurs when the clutch pack inside the torque converter fails to engage smoothly, creating a rhythmic vibration that travels through the entire floorboard of the SUV.
The Fundamentals: Understanding the 6F50 and 6F55 Transmissions
To fix a problem, you must first understand the hardware involved in the 2019 Explorer. Most 2019 models are equipped with the 6F50 or the heavy-duty 6F55 6-speed automatic transmission. These units were developed through a partnership between Ford and GM, designed to balance fuel economy with the torque requirements of a heavy SUV.
The 6F series relies heavily on a complex valve body and an array of electronic solenoids to manage fluid flow. Unlike older transmissions that used mechanical linkages, these modern units use “shift-by-wire” logic. This means that a small electrical glitch can cause the same physical symptoms as a broken gear, making electronic diagnosis a mandatory first step.
The 6F55 variant is typically found in the Sport and Platinum trims equipped with the 3.5L EcoBoost engine. Because these engines produce significantly more torque, the transmission is under higher thermal stress. If you use your Explorer for heavy towing or off-road adventures, the heat generated can degrade the fluid much faster than the manual suggests.
Step-by-Step Diagnostic Guide for the DIY Mechanic
If you suspect your vehicle is developing 2019 Ford Explorer transmission problems, do not panic. Before heading to a transmission shop, perform these basic checks to narrow down the cause. You can do most of these in your driveway with basic hand tools and a bit of patience.
- Check the Fluid Level and Condition: Locate the transmission dipstick (some models may require a specialized procedure). The fluid should be a bright translucent red. If it is dark brown or smells like burnt toast, the internal clutches are likely slipping and burning.
- Scan for Diagnostic Trouble Codes (DTCs): Plug an OBD-II scanner into the port under your dashboard. Look for codes starting with “P0700.” These codes specifically relate to the transmission control system and can tell you exactly which solenoid is acting up.
- Inspect for External Leaks: Crawl under the vehicle with a flashlight. Look at the transmission cooler lines and the pan gasket. Even a small leak can lead to low fluid levels, which causes the pump to cavitate and lose pressure.
- Perform a Battery Reset: Sometimes, the transmission’s “adaptive learning” memory gets corrupted. Disconnecting the negative battery terminal for 15 minutes can reset the shift logic, occasionally resolving minor harsh-shifting issues.
Essential Tools and Resources for Ford Transmission Work
Working on a modern Ford requires a few specialized items that you might not find in a generic tool kit. If you plan on tackling fluid changes or sensor replacements yourself, investing in the right gear will prevent stripped bolts and frustration. High-quality tools are the foundation of safety when working under a heavy vehicle.
For diagnostics, I highly recommend using FORScan software with a compatible OBD-II adapter. This is a powerful tool specifically designed for Ford vehicles, allowing you to see real-time data from the transmission’s pressure sensors. It provides much deeper insight than a cheap generic scanner found at a local auto parts store.
When it comes to hardware, you will need a set of metric sockets, a low-profile drain pan, and a fluid transfer pump. Since many modern Fords lack a traditional fill tube, you must pump the new fluid into the side of the transmission case. Always ensure you are using Mercon LV fluid, as using the wrong specification can lead to immediate mechanical damage.
Common Pitfalls and Mistakes to Avoid During Repair
One of the biggest mistakes owners make is ignoring the “Check Engine” or “Wrench” light. Many 2019 Ford Explorer transmission problems start as minor electronic hiccups that are easily fixed with a solenoid replacement. If you keep driving, those hiccups turn into physical wear on the clutch plates, requiring a $4,000 rebuild.
Another common pitfall is performing a “transmission flush” at a high-pressure service center. For a high-mileage 2019 Explorer, a high-pressure flush can dislodge metal shavings and debris, forcing them into the delicate valve body passages. Instead, opt for a “drain and fill” service, which is much gentler on the internal components.
Finally, never attempt to work on the transmission while the vehicle is supported only by a floor jack. Always use heavy-duty jack stands and wheel chocks. Transmission fluid is also highly flammable and slippery; keep a bag of oil absorbent nearby to prevent slips and falls in your workspace.
Real-World Scenarios: Off-Roading and Towing Stress
The 2019 Explorer is a favorite for overlanding and towing small boats. However, these activities put immense pressure on the torque converter lock-up clutch. When you are climbing a steep grade or pulling a trailer, the transmission generates extreme heat. If the fluid temperature exceeds 230 degrees Fahrenheit, it begins to break down chemically.
If you frequently take your Explorer off-road, consider installing an auxiliary transmission cooler. This is a secondary radiator that helps dissipate heat before the fluid returns to the gearbox. It is a relatively inexpensive modification that can double the lifespan of your transmission in harsh environments.
Always remember to use the “Tow/Haul” mode button on your center console. This feature changes the shift points to keep the engine in its power band and increases line pressure within the transmission. This prevents the clutches from slipping under heavy loads, which is a primary cause of 2019 Ford Explorer transmission problems during long trips.
Future Trends and Long-Term Maintenance for the Explorer
As the 2019 model ages, we are seeing a trend toward electronic “lead frame” failures. This is a plastic housing inside the transmission that holds the wiring for the sensors. Over time, heat cycles cause the plastic to crack, leading to intermittent speed sensor signals. Ford has issued several Technical Service Bulletins (TSBs) regarding this, so check your VIN for any open recalls.
For long-term reliability, ignore the “lifetime fluid” claims often found in owner manuals. In the real world, changing your transmission fluid every 30,000 to 50,000 miles is the best insurance policy you can buy. This ensures that the friction modifiers in the fluid remain active, protecting the gears from premature wear.
Keeping an eye on the market, we see more owners moving toward specialized synthetic fluids that offer better thermal stability. While Mercon LV is the standard, some high-performance synthetics can provide smoother shifting in extreme cold or heat. Always consult with a licensed professional before switching fluid types to ensure compatibility with your specific 2019 Explorer build.
Frequently Asked Questions About 2019 Ford Explorer transmission problems
How much does it cost to fix a 2019 Ford Explorer transmission?
Minor repairs like a solenoid replacement or a software reflash typically cost between $300 and $800. However, if the entire unit needs a rebuild or replacement, you can expect to pay between $3,500 and $5,000 depending on your location and the shop’s labor rates.
Is there a recall for the 2019 Ford Explorer transmission?
While there have been several recalls for the Explorer line involving suspension and brakes, the 2019 transmission has mostly been covered by Technical Service Bulletins (TSBs) rather than safety recalls. TSBs provide instructions for dealers to fix known issues but don’t always result in a free repair outside of warranty.
Can I drive my Explorer with a transmission shudder?
You should avoid driving long distances if you feel a shudder. This vibration indicates that the torque converter is slipping, which generates excessive heat. Continued driving will eventually contaminate the entire system with metal debris, leading to a much more expensive repair bill.
What is the most common cause of shifting issues in this model?
The most common culprit is often the Electronic Control Unit (ECU) or the transmission solenoids. Because these vehicles are so reliant on electronics, a simple sensor failure can mimic a major mechanical breakdown. Always start with an electronic diagnostic before assuming the gears are broken.
