Common Symptoms of 2017 Ford Explorer Transmission Problems

Identifying transmission issues early can save you a significant amount of time and money. Your Explorer’s transmission communicates its distress through various tell-tale signs. Paying close attention to these symptoms is your first line of defense.

Rough Shifting or Hesitation Between Gears

One of the most frequently reported issues is a noticeable roughness or hesitation when the transmission shifts gears. This can manifest as a jarring sensation or a delay in engaging the next gear.

You might feel a sudden lurch or clunk during acceleration or deceleration.
Sometimes, the engine RPMs will flare up before the transmission finally engages.
This can be particularly noticeable when shifting from park to drive or reverse, or during low-speed city driving.

Delayed Engagement or No Engagement

When you put your Explorer into drive or reverse, you expect an immediate response. If there’s a delay, or if the transmission doesn’t engage at all, it’s a serious red flag.

A few seconds of delay before the gear engages can indicate low fluid pressure or internal wear.
Complete lack of engagement means the vehicle won’t move, even with the engine running. This usually points to significant internal damage or a critical sensor failure.

Slipping Transmission

Transmission slipping is another common symptom where the engine revs up, but the vehicle doesn’t accelerate as expected. It feels like the power isn’t fully transferring to the wheels.

This often happens under acceleration, especially when climbing hills or towing.
It can feel similar to a worn clutch in a manual transmission vehicle.
Slipping can rapidly worsen, leading to complete loss of drive if ignored.

Warning Lights on the Dashboard

Modern vehicles are equipped with sophisticated diagnostic systems. Never ignore a warning light, especially if it’s related to the powertrain.

The Check Engine Light (CEL) can illuminate for various reasons, including transmission-related codes.
Some Explorers might display a specific “Transmission Malfunction” message or a wrench icon.
It’s crucial to get these codes read with an OBD-II scanner as soon as possible.

Unusual Noises or Vibrations

Your Explorer’s transmission should operate quietly and smoothly. Any new noises or vibrations are cause for concern.

Whining, clunking, humming, or grinding noises coming from under the vehicle can indicate internal component wear.
Vibrations felt through the steering wheel, floorboard, or seats, especially during shifts, also point to potential issues.

Leaking Transmission Fluid

A puddle under your Explorer is never a good sign. Transmission fluid is typically reddish-brown and has a distinct sweet smell.

Even small leaks can lead to low fluid levels, which severely impact transmission performance and longevity.
Check the area around the transmission pan, cooler lines, and output shaft seals for any signs of leakage.

Understanding the Root Causes of 2017 Ford Explorer Transmission Problems

Pinpointing the exact cause of your Explorer’s transmission woes can be complex, as several factors contribute to these issues. Knowing the potential culprits helps in accurate diagnosis and repair.

The 6F50/6F55 Automatic Transmission

The 2017 Ford Explorer typically utilizes the 6F-series automatic transmission (either the 6F50 or 6F55 depending on the engine). While generally robust, these units have specific areas prone to wear.

Issues often stem from the valve body, solenoids, or torque converter.
Internal clutch pack wear can also lead to slipping and delayed engagement.

Low or Contaminated Transmission Fluid

Transmission fluid is the lifeblood of your gearbox, serving as a lubricant, coolant, and hydraulic medium. Its condition is paramount.

Low fluid level: Can cause slipping, hard shifts, and overheating due to insufficient hydraulic pressure. Leaks are the primary cause.
Contaminated fluid: Over time, fluid degrades, collects wear particles, and loses its lubricating properties. Dark, burnt-smelling fluid is a clear sign it needs changing.
Incorrect fluid type: Using the wrong type of transmission fluid can cause severe damage, as tolerances and friction modifiers are highly specific. Always use the manufacturer-specified MERCON LV fluid for your Explorer.

Solenoid and Valve Body Issues

The valve body is the “brain” of the automatic transmission, directing fluid pressure to engage clutches and bands. Solenoids are electronic valves within the valve body that control fluid flow based on signals from the transmission control module (TCM).

Sticking solenoids: Can cause delayed or harsh shifts, as they fail to open or close correctly.
Worn valve body: Internal passages can wear, leading to pressure loss and erratic shifting.
These components are critical for smooth operation, and their failure is a common source of 2017 Ford Explorer transmission problems.

Torque Converter Problems

The torque converter connects the engine to the transmission, allowing the engine to spin while the vehicle is stopped in gear. It also multiplies torque.

Lock-up clutch failure: Can cause shuddering, especially at highway speeds, and reduced fuel economy.
Internal wear: Can lead to unusual noises, overheating, and metal shavings contaminating the fluid.

Transmission Control Module (TCM) or Sensor Malfunctions

The TCM is the computer that manages the transmission’s operations, relying on data from various sensors (speed sensors, temperature sensors, etc.).

Faulty TCM: Can send incorrect signals, leading to erratic shifting or complete transmission failure.
Bad sensors: Incorrect sensor readings can confuse the TCM, resulting in poor shift quality or activating “limp home” mode.

Internal Mechanical Wear

Like any complex mechanical system, internal components of the transmission wear out over time.

Clutch packs, bands, gears, and bearings can wear down, leading to slipping, grinding, or complete failure.
This wear is often accelerated by aggressive driving, towing heavy loads, or neglected fluid maintenance.

DIY Diagnostics: What You Can Check at Home

Before rushing to a mechanic, there are several things a careful DIYer can check in their garage or driveway. Remember, safety first! Always use jack stands if you’re working under the vehicle.

Checking Transmission Fluid Level and Condition

This is the simplest and often most telling diagnostic step. Your 2017 Explorer might not have a traditional dipstick, so consult your owner’s manual for the correct procedure, which often involves checking fluid temperature and a specific fill plug.

Park on a level surface: Ensure the vehicle is level for an accurate reading.
Warm up the engine: Drive for about 15-20 minutes to bring the transmission fluid to operating temperature.
Locate the fill plug/check port: On Explorers without a dipstick, this is usually on the side of the transmission.
Inspect the fluid:
- Level: Ensure it’s within the manufacturer’s specified range. Low fluid is a common cause of hard shifts and slipping.
- Color: New fluid is typically reddish-pink. Dark brown or black fluid suggests contamination or degradation.
- Smell: A burnt smell indicates overheating and potential internal damage.
- Consistency: Look for metal particles or sludge, which signify significant internal wear.
Top off if needed: If the fluid is low and looks good otherwise, top it off with the correct MERCON LV fluid. Do not overfill.

Scanning for Diagnostic Trouble Codes (DTCs)

An OBD-II scanner is an invaluable tool for any DIY mechanic. It can read codes that illuminate your Check Engine Light.

Connect the scanner: Plug it into your Explorer’s OBD-II port, usually located under the dashboard on the driver’s side.
Read codes: Note down any P-codes (Powertrain codes), especially those starting with P07xx, P08xx, or P17xx, which are transmission-specific.
Research the codes: Use online resources or a service manual to understand what each code signifies. This can point directly to issues like a faulty speed sensor, solenoid, or even the TCM itself.

Visual Inspection for Leaks and Damage

Get under the vehicle (safely, with jack stands!) and perform a thorough visual inspection.

Look for fluid leaks: Check the transmission pan gasket, cooler lines, and output shaft seals. Any wet spots indicate a leak.
Inspect electrical connectors: Ensure all wiring harnesses connected to the transmission and sensors are securely plugged in and free from corrosion or damage.
Check for physical damage: Look for dents on the transmission pan, which could indicate impact damage and potential internal issues.

Test Driving and Observing Symptoms

A structured test drive can help confirm symptoms and observe how the transmission behaves under different conditions.

Listen for noises: Pay attention to any whining, grinding, or clunking during shifts or while cruising.
Feel for shifts: Note if shifts are harsh, delayed, or if the transmission slips under acceleration.
Observe RPMs: Watch the tachometer for unusual fluctuations or “flaring” between shifts.
Highway shudder: If you feel a shudder at consistent highway speeds, it might indicate a torque converter lock-up issue.

When to Call a Professional: Recognizing Limitations

While DIY diagnostics are empowering, knowing when to bring in a licensed professional is crucial. Attempting complex transmission repairs without the right tools, knowledge, or experience can lead to further, more expensive damage. For significant 2017 Ford Explorer transmission problems, professional intervention is often the safest and most cost-effective path.

Complex Internal Issues

If your diagnostics point to internal wear, valve body issues, or torque converter failure, it’s time for an expert.

These repairs often require specialized tools, precise measurements, and a clean environment.
A professional transmission shop has the expertise to correctly diagnose and rebuild or replace components.

Persistent Warning Lights

If your Check Engine Light or Transmission Malfunction warning persists after basic checks, or if it’s accompanied by severe symptoms, don’t delay.

Some codes indicate critical failures that require immediate attention.
Ignoring these can lead to complete transmission breakdown, potentially stranding you.

No Movement or Limp Mode

If your Explorer won’t move, or if it’s stuck in “limp home” mode (where it only uses one or two gears to prevent further damage), it’s not safe to drive. Call a tow truck.

Limp mode is a protective measure, but it means a significant fault has been detected.

Off-Roading Considerations and Trailside Trouble

For off-road enthusiasts, transmission issues can be particularly dangerous. If you’re deep in the wilderness and experience severe transmission problems:

Do not push it: Trying to force a failing transmission to get you out can cause catastrophic damage.
Assess your options: If you’re within cell service, call for assistance. If not, evaluate if you can safely walk out or signal for help.
Consider satellite communicators: For serious off-roaders, devices like a Garmin inReach or Zoleo are vital for summoning help when out of range.
Always carry recovery gear: A winch, recovery straps, and a shovel can help you get out of a minor bind, but they won’t fix a major transmission issue.
Know your limits: If you’re unsure, err on the side of caution and call for a professional recovery. Park rangers or experienced off-road guides can also be valuable resources in remote areas.

Maintenance and Prevention: Protecting Your Explorer’s Transmission

Proactive maintenance is the best defense against costly 2017 Ford Explorer transmission problems. A little care goes a long way in extending the life of your vehicle’s most complex component.

Regular Transmission Fluid Changes

This is arguably the most critical maintenance item. Follow Ford’s recommended service intervals for transmission fluid and filter changes, especially if you tow or drive in harsh conditions.

Consult your owner’s manual: Ford typically recommends fluid changes every 60,000 to 100,000 miles, but this can vary.
Consider severe duty intervals: If you frequently tow, drive in stop-and-go traffic, or in extreme temperatures, consider changing the fluid more often (e.g., every 30,000-50,000 miles).
Use the correct fluid: Always use MERCON LV automatic transmission fluid. Using an incorrect fluid can cause irreversible damage.

Keep an Eye on Fluid Levels

Even between scheduled changes, regularly check your transmission fluid level (if your Explorer has a dipstick or a check port). A consistently low level indicates a leak that needs addressing.

Maintain Your Cooling System

Overheating is a major enemy of automatic transmissions. Ensure your engine’s cooling system is in top shape, as transmission fluid often runs through a cooler integrated with the radiator.

Check coolant levels and condition regularly.
Ensure your radiator and cooling fans are functioning correctly.
Consider an auxiliary transmission cooler if you frequently tow heavy loads or drive in hot climates.

Drive Smart

Your driving habits directly impact transmission longevity.

Avoid aggressive acceleration: Gradual acceleration puts less stress on clutch packs and gears.
Use proper towing techniques: If towing, use the appropriate tow/haul mode and avoid overloading your Explorer. This helps prevent excessive heat and strain on the transmission.
Allow for warm-up: In cold weather, give your Explorer a minute or two to warm up before driving, allowing fluids to circulate.

Address Minor Issues Promptly

Don’t ignore subtle symptoms like a slight hesitation or a small leak. Addressing minor issues before they escalate can prevent major breakdowns.

Even a small solenoid issue, if left unaddressed, can lead to increased wear on other components.
