This article explains the transmission pairing for the 3.5 L EcoBoost V6 in Expedition, what that means for performance and towing, and how it varies across model years.

Understanding the 10R80 transmission

The Ford 10R80 is a 10‑speed automatic transmission designed to handle the EcoBoost V6’s torque while delivering smooth, quick shifts. It is electronically controlled with adaptive shift logic to optimize performance under a variety of driving conditions.

Key features of the 10R80 in the Expedition

Before listing the main capabilities, note that the transmission is designed to maximize power delivery, improve efficiency, and integrate with the Expedition’s drivetrain and drive modes.

• 10-speed automatic transmission (Ford 10R80) capable of handling high-torque EcoBoost engines


• Adaptive shift scheduling that learns driving style and payload to optimize gear selection


• Wide gear ratio spread for strong low-end response and efficient highway cruising


• Tow/Haul and selectable drive modes to tailor shifting for towing and different driving conditions


• Seamless integration with AWD/4WD systems for consistent power delivery


• Durable design built to withstand the torque and payload demands of the Expedition family

In summary, the 10R80 10-speed automatic is chosen to balance acceleration, towing capability, and fuel efficiency for the Expedition equipped with the 3.5 L EcoBoost V6.

Model-year and configuration notes

In the modern Expedition lineup, the 3.5 L EcoBoost V6 is paired with the Ford 10R80 10-speed automatic transmission. For older or regional variations, transmission configurations can differ, so it’s always best to verify the specific build sheet or owner’s manual for a given vehicle.

Summary

The Ford Expedition’s 3.5 L EcoBoost V6 is paired with a 10-speed automatic transmission (Ford 10R80). This setup is designed to deliver smooth shifts, strong towing performance, and improved efficiency across current models.

What is the bad year for the Ford Expedition?

The worst years for the Ford Expedition are generally considered to be 2003-2006 due to a high number of engine, electrical, and transmission issues, as well as 2017-2019 for powertrain problems like rough-shifting and running board failures. Specific models to avoid include 2003, which has the most complaints overall, and 2004, which is noted for severe engine problems. 
Older models to avoid

• 2003–2006: This generation has a reputation for major problems.
  • 2003: Received the most complaints overall, with issues including spark plug ejection, brake failures, and other engine and electrical problems.
  • 2004: Specifically known for engine problems, including a well-documented spark plug ejection issue.
  • 1997–2007: Spark plug ejection was a documented problem across this range.

Newer models to avoid

• 2017–2019: Consumer Reports flagged these years for reliability issues, particularly with the powertrain. 
  • 2017–2018: Recalls related to the brake master cylinder have been issued. 
  • 2018–2020: While offering good performance, these years are associated with high price tags and poor fuel economy, especially when towing. 
• 2011: This model year received many complaints about powertrain issues, including the engine surging unexpectedly and transmission problems. 

Other models with reported issues

• 2021–2025: Some owners have reported transmission issues, such as rough shifting and slipping. 

What year did 3.5 EcoBoost stay away from?

Vehicle owners should steer clear of first-generation 3.5 EcoBoost engines made between 2010 and 2014. These years show higher risks for Ford 3.5 EcoBoost problems like carbon build-up and timing chain stretching.

Is the 3.5 L EcoBoost V-6 a good engine?

The 3.5L EcoBoost engine is considered powerful and a good choice for many applications, but its reliability varies by model year and requires diligent maintenance. Early models (2010-2014) are more prone to issues like carbon buildup and timing chain wear, while later versions have improved. Key maintenance, such as regular oil changes, is crucial to prevent problems like timing chain stretch.

Pros

• Powerful performance: It provides significant horsepower and torque, making it excellent for towing and everyday driving. 
• Fuel efficiency: Despite its power, it can be more fuel-efficient than traditional V8 engines when not under heavy load. 
• Versatile: It's a popular engine in vehicles like the Ford F-150, Explorer, and others, and can be modified for even more power. 

Cons

• Maintenance-intensive: It requires strict adherence to maintenance schedules, especially oil changes, to prevent issues like timing chain wear. 
• Potential for specific problems:
  • Early models (2010-2014) have a higher risk of carbon buildup on intake valves and timing chain stretching. 
  • Condensation in the intercooler can occur in high-humidity, damp conditions, leading to performance issues. 
• Complexity: As a twin-turbocharged engine, it has more parts that can potentially fail compared to simpler naturally aspirated engines.

What to consider

• Model year: Be cautious with early models (2010-2014) due to known issues. Later models have seen improvements, but maintenance history is key. 
• Maintenance history: When buying used, the maintenance history is crucial. If you can't verify it, be prepared for potential repairs, especially around the 100,000-mile mark. 
• Driving habits: Your driving habits will affect reliability. Frequent heavy acceleration and towing require more diligent maintenance. 
• Warranty: Engines out of warranty will require the owner to cover any repair costs.
