This guide demystifies the process for your sealed transmission, offering expert steps to ensure proper fluid levels and prevent costly repairs, whether you’re a DIY enthusiast or preparing for an adventure.
Many modern vehicles, including the popular 2020 Ford Explorer, feature “sealed for life” transmissions, which can make routine maintenance like checking fluid levels seem daunting. You might wonder if it’s even necessary or how to approach it without a traditional dipstick.
Rest assured, while these systems are designed for extended intervals, knowing how to properly monitor your transmission fluid is a critical skill for any conscientious owner. We’ll guide you through the specifics, providing clear, actionable steps.
This comprehensive guide will equip you with the knowledge to confidently perform a 2020 Ford Explorer transmission fluid check, understand why it’s important, and recognize when professional intervention is needed to safeguard your vehicle’s performance and extend its life.
Understanding Your 2020 Ford Explorer’s Transmission System
The 2020 Ford Explorer, like many contemporary vehicles, uses an advanced 10-speed automatic transmission designed for efficiency and durability. These transmissions are often referred to as “sealed units.”
This design choice has significant implications for how you approach maintenance and fluid checks.
Why No Dipstick? The “Sealed for Life” Concept
The term “sealed for life” often causes confusion. It doesn’t mean the fluid never needs attention; rather, it implies that under normal driving conditions, the fluid should last the vehicle’s lifespan without routine checks or changes.
However, this ideal scenario doesn’t account for severe driving conditions, towing, off-roading, or simply the passage of time and miles. Ford’s official service schedules still recommend inspection or replacement under specific circumstances.
The absence of a traditional dipstick means checking the fluid level requires accessing a specific check plug on the transmission itself, which can be a more involved process than older vehicles.
The Importance of Transmission Fluid for Modern Explorers
Automatic transmission fluid (ATF) is the lifeblood of your Explorer’s gearbox. It serves multiple critical functions beyond just lubrication.
ATF cools the transmission, transmits power from the engine to the wheels via the torque converter, and provides hydraulic pressure for gear changes.
Proper fluid levels and quality are paramount for smooth shifting, preventing overheating, and extending the life of complex internal components like the valve body and clutch packs.
Recognizing Symptoms of Low or Bad Fluid
Even without a dipstick, your Explorer will often tell you if its transmission fluid is in distress. Pay close attention to these warning signs.
Common symptoms include delayed engagement when shifting into drive or reverse, harsh or erratic shifts, a noticeable shudder, or slipping gears where the engine revs but the vehicle doesn’t accelerate proportionally.
A burning smell, often likened to burnt toast, is a strong indicator of severely overheated or degraded fluid. If you notice any of these, an immediate inspection is warranted, potentially including a 2020 Ford Explorer transmission fluid check.
Essential Tools and Safety Gear for a 2020 Ford Explorer Transmission Fluid Check
Before you begin any work on your vehicle, especially underneath it, preparation is key. Gathering the right tools and prioritizing safety will make the process smoother and safer.
This section outlines everything you’ll need to perform a thorough 2020 Ford Explorer transmission fluid check.
Required Tools and Materials
You’ll need a specific set of items for this job, as it’s not as simple as popping a hood and pulling a dipstick.
- Floor Jack and Jack Stands: Essential for safely lifting and supporting your Explorer. Never rely solely on a jack.
- Wheel Chocks: To prevent the vehicle from rolling while lifted.
- Socket Wrench Set: Including sockets for the transmission drain and check plugs.
- Torque Wrench: Crucial for tightening plugs to factory specifications, preventing leaks or damage.
- Drain Pan: To catch any overflowing fluid during the check.
- Fluid Pump with Hose: If you need to add fluid, a pump is necessary for sealed transmissions.
- Funnel: For adding fluid to the pump reservoir.
- Clean Rags or Shop Towels: For cleaning up spills.
- New Mercon LV Automatic Transmission Fluid: Only use Ford-approved Mercon LV. Using the wrong fluid can cause severe transmission damage.
Prioritizing Your Safety
Safety should always be your number one concern when working on any vehicle. Never cut corners, especially when lifting your Explorer.
Always work on a level, stable surface. Ensure the vehicle is in park with the parking brake engaged and wheels chocked before lifting.
Use personal protective equipment (PPE) such as safety glasses to protect your eyes from fluid splashes and mechanics gloves to keep your hands clean and protected from hot components and sharp edges.
Step-by-Step Guide to Checking Your Explorer’s Transmission Fluid Level
This procedure requires patience and attention to detail. Follow these steps carefully to accurately assess your transmission fluid level.
Pre-Check Preparations: Warm-up and Level Ground
The transmission fluid level must be checked at the correct operating temperature for an accurate reading. Cold fluid will give a false low reading.
Drive your Explorer for about 15-20 minutes until the transmission reaches its normal operating temperature (typically 190-200°F). If you have access to a diagnostic scan tool, you can monitor the transmission fluid temperature (TFT).
Park the vehicle on a perfectly level surface. This is critical for an accurate fluid level measurement. Engage the parking brake and place wheel chocks behind the rear wheels.
Safely Lifting Your Vehicle
With the engine still running and the transmission at operating temperature, carefully lift the front of your Explorer using a floor jack.
Position jack stands securely under the designated frame points, ensuring the vehicle is stable and level once lowered onto the stands. You’ll need enough clearance to work comfortably underneath the vehicle.
Once stable on jack stands, turn the engine off. While some older vehicles required the engine to be running during a check, Ford’s modern 10-speed transmission often specifies checking with the engine off after warm-up. Always consult your owner’s manual for the precise procedure for your specific model year.
Locating the Transmission Fill/Check Plug
The 2020 Ford Explorer’s transmission does not have a traditional dipstick tube. Instead, you’ll be looking for a specific plug on the side or bottom of the transmission pan.
Locate the transmission pan, which is typically a flat, metallic component at the bottom of the transmission assembly. You’ll find two plugs: a larger drain plug and a smaller fill/check plug.
The check plug is usually located towards the rear of the pan or on the side, slightly above the drain plug. It may be marked or have a unique shape. Refer to your Explorer’s service manual or an online diagram if you have trouble locating it.
The Fluid Level Inspection Procedure
With your drain pan positioned underneath, carefully remove the transmission fill/check plug using the appropriate socket. Be prepared for a small amount of fluid to trickle out.
- If fluid immediately streams out, the transmission is likely overfilled. This can also cause problems and should be addressed.
- If fluid slowly drips or doesn’t come out at all, the fluid level is low. This is the most common scenario indicating a need to add fluid.
- If a steady stream of fluid comes out, then tapers off to a drip, the fluid level is generally correct.
Observe the color and smell of any fluid that comes out. Healthy Mercon LV fluid is typically reddish-pink and transparent. If it’s dark brown or black, smells burnt, or contains metallic particles, it’s a strong sign that a fluid change, not just a top-off, is desperately needed.
Interpreting Your Findings and What to Do Next
Based on your inspection, you’ll need to take appropriate action. If the level is correct, simply reinstall the check plug and tighten it to the manufacturer’s specified torque.
If the level is low, you’ll need to add the correct Mercon LV fluid using your fluid pump. Pump fluid into the check hole until it begins to steadily stream out, then quickly reinstall the plug.
If the fluid is burnt or contaminated, adding more fluid is only a temporary band-aid. A full transmission fluid drain and fill (or even a flush by a professional) is recommended to prevent further damage. This is a critical decision point for any DIYer.
When to Consider a Transmission Fluid Change on Your 2020 Explorer
While checking the fluid is important, knowing when to change it entirely is equally vital for the long-term health of your 2020 Explorer’s transmission.
Ford’s Official Maintenance Schedule
Ford’s owner’s manual typically provides specific maintenance intervals for the transmission fluid. For many 2020 Explorers under normal driving conditions, the interval for inspection or replacement might be quite long, often 100,000 to 150,000 miles.
However, it’s crucial to consult your specific owner’s manual, as variations can exist. Don’t rely on generic advice; your manual is the definitive source for your vehicle’s needs.
Factors Influencing Fluid Lifespan (Towing, Off-roading)
The “normal driving conditions” specified by Ford often don’t apply to everyone. If you regularly tow heavy loads, engage in frequent stop-and-go city driving, or venture off-road, your transmission experiences significantly more stress.
These severe duty conditions lead to higher operating temperatures, which break down transmission fluid much faster. In such cases, a fluid change interval of 30,000 to 60,000 miles is often a much wiser preventative measure.
For off-road enthusiasts, especially those tackling challenging terrain, regular inspection and fluid changes are non-negotiable. The added stress on the drivetrain demands a proactive approach to maintenance.
The Difference Between a Check and a Change
It’s important to differentiate between checking the fluid level and performing a fluid change. A check simply verifies the volume and condition of the existing fluid.
A fluid change, or drain and fill, involves draining the old fluid from the transmission pan and refilling it with fresh fluid. This replaces a significant portion of the old fluid but not typically 100% (as some remains in the torque converter and cooler lines).
A “flush” performed by a professional uses specialized equipment to exchange nearly all of the old fluid with new. This can be beneficial but should only be done if the fluid isn’t severely contaminated or if the transmission is already showing signs of distress, as a flush can sometimes dislodge debris and cause further issues in an already compromised unit.
Pro Tips and Common Pitfalls to Avoid
Even for experienced DIYers, a 2020 Ford Explorer transmission fluid check has its nuances. Here are some expert insights to help you avoid common mistakes and ensure a successful outcome.
Using the Correct Fluid Type (Mercon LV)
This is perhaps the single most critical piece of advice: ONLY use Ford-approved Mercon LV automatic transmission fluid. Modern transmissions are highly sensitive to fluid properties.
Using the wrong type of fluid, even if it claims to be “multi-vehicle” or “compatible,” can lead to premature wear, poor shifting performance, and catastrophic transmission failure. Always double-check the label and your owner’s manual.
Ford’s Mercon LV is engineered with specific friction modifiers and viscosity characteristics tailored to their 10-speed transmissions.
Overfilling vs. Underfilling
Both underfilling and overfilling your transmission fluid can cause serious problems. Underfilling leads to fluid starvation, overheating, and component wear.
Overfilling can cause aeration (foaming) of the fluid, which reduces its lubricating and cooling capabilities. It can also create excessive pressure, leading to leaks and seal damage.
This is why the “stream then drip” method for checking the sealed transmission plug is so important – it helps ensure the fluid is at the precise level required by the manufacturer.
When to Call a Professional Mechanic
While a fluid check is a manageable DIY task for many, there are times when calling a licensed professional is the smartest move. If you’re uncomfortable lifting your vehicle, can’t locate the check plug, or are unsure about any step, seek help.
If your fluid is severely burnt, contains metallic debris, or if your transmission is already exhibiting significant shifting problems, it’s time for a diagnostic visit to a Ford dealership or a trusted independent transmission specialist.
They have specialized diagnostic tools to read transmission fault codes and perform comprehensive assessments that go beyond a simple fluid level check. Don’t hesitate to consult an expert to prevent a small issue from becoming a major, costly repair.
Frequently Asked Questions About Your 2020 Ford Explorer’s Transmission
Here are some common questions we hear regarding the transmission fluid in the 2020 Ford Explorer.
How often should I check my transmission fluid?
While Ford’s “sealed for life” concept suggests infrequent checks, it’s wise to visually inspect for leaks during every oil change. For drivers under severe conditions (towing, off-roading, heavy city driving), consider performing a fluid level check every 30,000 miles or annually, along with a full fluid change every 60,000 miles.
Can I use any ATF in my 2020 Explorer?
Absolutely not. You must use Ford-approved Mercon LV (Low Viscosity) automatic transmission fluid. Using any other type of ATF can lead to severe transmission damage and void your warranty.
What are the signs of a failing transmission?
Common signs include delayed engagement, harsh or erratic shifts, slipping gears (engine revs but vehicle doesn’t accelerate), a burning smell, grinding noises, or the transmission warning light illuminating on your dashboard. Any of these warrant immediate professional inspection.
Is a transmission flush better than a drain and fill?
A full transmission flush exchanges nearly all the old fluid, while a drain and fill replaces only a portion. A flush can be beneficial for preventative maintenance on a healthy transmission. However, if your transmission is already experiencing problems or has very high mileage with neglected fluid, a flush can sometimes dislodge debris and worsen issues. Consult a professional to determine the best approach for your specific situation.
Performing a 2020 Ford Explorer transmission fluid check is a valuable skill for any owner, empowering you to monitor your vehicle’s health and potentially catch issues before they escalate. Remember, modern transmissions are complex, and while DIY checks are feasible, knowing when to call in professional expertise is a mark of a truly knowledgeable owner.
By following these steps, prioritizing safety, and using the correct fluids and tools, you’re taking a significant step in ensuring the longevity and optimal performance of your Explorer’s drivetrain. Stay vigilant, stay safe, and enjoy the open road!
