The 2019 Ford Expedition, a powerhouse SUV known for its spaciousness and towing capability, unfortunately, isn't immune to its fair share of problems, and one area that's raised concerns for many owners is the transmission. A malfunctioning transmission can turn a smooth ride into a jerky, unpredictable experience, and understanding the potential issues is the first step towards keeping your Expedition running strong. Let's dive into the common transmission problems plaguing the 2019 Expedition and what you can do about them.

What's Going On With My Expedition's Transmission? Common Culprits

The 2019 Expedition utilizes a 10-speed automatic transmission (10R80), co-developed with General Motors. While generally reliable, this transmission, like any complex mechanical system, can experience issues. Here are some of the most frequently reported problems:

  • Harsh Shifting: This is probably the most common complaint. Owners report rough or jerky shifts, especially between lower gears. It can feel like the transmission is "slamming" into gear, rather than smoothly transitioning.
  • Delayed Engagement: When shifting from Park to Drive or Reverse, there might be a noticeable delay before the transmission engages. This can be unsettling, especially in traffic.
  • Slipping Gears: The engine revs higher than usual without a corresponding increase in speed. This indicates the transmission isn't properly transferring power from the engine to the wheels.
  • Shuddering or Vibrating: Some owners experience a shuddering or vibrating sensation, particularly at lower speeds or during light acceleration. This can be caused by various issues, including torque converter problems.
  • Complete Transmission Failure: While less common than the issues above, complete transmission failure can occur, rendering the vehicle undriveable. This usually involves more serious internal damage.
  • Error Codes and Warning Lights: The check engine light or a specific transmission warning light may illuminate on the dashboard, indicating a problem. These codes can provide valuable clues for diagnosis.
  • Difficulty Downshifting: Experiencing resistance or delays when the transmission needs to downshift, especially when slowing down or going uphill.
  • Unusual Noises: Grinding, whining, or clunking sounds coming from the transmission area are often signs of trouble.

Why Is This Happening? Decoding the Potential Causes

Understanding what is happening is important, but understanding why it's happening can help prevent future problems. Here's a breakdown of some of the underlying causes of these transmission issues:

  • Software Glitches: The 10R80 transmission relies heavily on electronic control. Software glitches or programming errors can lead to erratic shifting behavior.
  • Low or Contaminated Transmission Fluid: Transmission fluid lubricates and cools the internal components of the transmission. Low fluid levels or contaminated fluid can cause increased friction, overheating, and premature wear.
  • Valve Body Issues: The valve body controls the flow of transmission fluid to different parts of the transmission. Malfunctioning valves can disrupt the shifting process.
  • Torque Converter Problems: The torque converter acts as a fluid coupling between the engine and the transmission. Failure of the torque converter can lead to shuddering, slipping, and other performance issues.
  • Internal Component Wear: Over time, internal components like clutches, gears, and bearings can wear out, leading to transmission problems. This is especially true if the transmission hasn't been properly maintained.
  • Overheating: Excessive heat can damage transmission components and accelerate wear. Towing heavy loads or driving in extreme conditions can contribute to overheating.
  • Sensor Malfunctions: Various sensors monitor the transmission's operation and provide data to the control module. Faulty sensors can lead to inaccurate readings and incorrect shifting decisions.

What Can I Do About It? Troubleshooting and Solutions

So, your Expedition is acting up. What are your options? Here's a step-by-step approach to troubleshooting and potential solutions:

  1. Check the Transmission Fluid: This is the easiest and most basic step. Locate the transmission fluid dipstick (consult your owner's manual if you're unsure where it is). Check the fluid level and condition. The fluid should be a clear, reddish color. If it's low, add the correct type of transmission fluid (refer to your owner's manual). If it's dark, sludgy, or smells burnt, it needs to be changed.
  2. Scan for Error Codes: Use an OBD-II scanner to check for any stored error codes. These codes can provide valuable clues about the nature of the problem. You can purchase a scanner yourself or take your vehicle to a mechanic for a scan.
  3. Consider a Transmission Fluid Flush: If the transmission fluid is contaminated, a fluid flush can help remove debris and restore proper lubrication. However, be aware that a flush can sometimes dislodge accumulated deposits, potentially worsening existing problems in older transmissions. Discuss the pros and cons with a qualified mechanic before proceeding.
  4. Check for Software Updates: Ford may release software updates for the transmission control module (TCM) to address known issues. Check with your dealer to see if any updates are available for your vehicle.
  5. Inspect the Valve Body: A malfunctioning valve body can cause a variety of shifting problems. A mechanic can inspect the valve body for damage or wear and replace it if necessary.
  6. Address Torque Converter Issues: If you suspect a torque converter problem, a mechanic can perform tests to confirm the diagnosis. Repair options may include replacing the torque converter.
  7. Seek Professional Diagnosis: If you're unable to diagnose the problem yourself, or if the problem persists after trying the above steps, it's best to take your vehicle to a qualified mechanic who specializes in transmissions. They have the tools and expertise to accurately diagnose the problem and recommend the appropriate repair.
  8. Preventative Maintenance: Regular transmission service, including fluid changes at the recommended intervals, is crucial for preventing future problems. Follow Ford's recommended maintenance schedule for your Expedition.

Is There a Recall? Staying Informed

It's important to stay informed about any recalls or technical service bulletins (TSBs) that may apply to your 2019 Ford Expedition's transmission. Recalls are issued when a safety-related defect is identified, and Ford will typically cover the cost of repairs. TSBs provide guidance to technicians on how to address common problems. You can check for recalls and TSBs on the National Highway Traffic Safety Administration (NHTSA) website (nhtsa.gov) or by contacting your Ford dealer.
