Review FORD Reman Torque Converter Rwd/4x4 Transit 3.5 3.7 5.0 fits F-150 RWD 4X4 2016–2017

The **Ford DF109 6R80 Torque Converter** is a high-performance, heavy-duty transmission component designed exclusively for the **2016-2017 Ford F-150 Super Duty (Transit)**, offering seamless power delivery across a range of engine configurations, including the **3.5L EcoBoost V6, 3.7L Power Stroke V6, 5.0L Coyote V8, and 6.2L Power Stroke V8**. Engineered to complement the **6R80 8-speed automatic transmission**, this torque converter is built to handle the demanding torque outputs of both **RWD and 4x4 (4WD) drivetrains**, ensuring robust performance whether hauling heavy loads, towing substantial trailers, or navigating rugged off-road terrain. Its **stamped aluminum housing** provides a lightweight yet durable structure, while the **multi-plate clutch pack** delivers smooth, progressive engagement, reducing jerkiness during shifts and enhancing overall drivability. The **sprag-type kickdown mechanism** allows for rapid downshifts under heavy loads, optimizing acceleration and fuel efficiency when needed, while the **integrated torque converter clutch (TCC)** minimizes slippage at highway speeds, improving fuel economy without sacrificing power. Built to withstand the extreme demands of commercial and off-road applications, this torque converter features **high-temperature-resistant materials** and **precision-balanced components** to prevent wear, ensuring longevity even under continuous heavy-duty use. Whether paired with a **turbocharged EcoBoost V6** for fuel-efficient towing or a **high-torque Power Stroke diesel V8** for extreme hauling, the DF109 6R80 torque converter is a critical upgrade for those seeking **superior shift quality, durability, and performance** in their Ford F-150.

### **Pros and Cons of Buying a Ford F-150 (2016-2017) with a 6R80 Torque Converter (RWD/4x4, 3.5L EcoBoost, 3.7L V6, 5.0L V8)**

#### **Pros**

1. **Reliability of the 6R80 Transmission**

- The 6R80 is a robust, proven transmission used in Ford s full-size trucks and SUVs. It handles heavy loads well and is less prone to major failures compared to earlier transmissions in the F-150 lineup.

- With proper maintenance (fluid changes every 60,000 100,000 miles), it can last the life of the truck.

2. **Strong Engine Options**

- **3.5L EcoBoost (Twin-Turbo V6):** Offers strong power (310 350 hp) with decent fuel economy ( 18 20 MPG combined). It s reliable if maintained but may require more frequent oil changes due to turbocharging.

- **3.7L Ti-VCT V6:** A durable, fuel-efficient option (200 hp, 20 MPG combined) with fewer issues than turbocharged engines. Good for daily driving and light towing.

- **5.0L V8:** A classic, high-revving engine (365 hp) with strong towing capacity (up to 8,200 lbs with proper setup). Known for longevity if the valve cover gaskets and oil changes are kept up.

3. **4x4 Capability**

- The 4x4 system is reliable for off-road and light-duty hauling. The 2016 2017 models have a solid locking differential (if equipped) and good ground clearance ( 8.5 inches).

- Useful for light trailering, snow removal, or occasional off-roading.

5. **Comfortable Ride and Interior Quality**

- The F-150 offers a smooth ride for a truck, especially with the available **Mag-A-Glo** or **Mag-A-Glo Plus** interiors, which are more durable than standard plastics.

- Available features like **SYNC 3**, **heated seats**, and **power-adjustable seats** improve comfort for long drives.

6. **Good Resale Value**

- Ford F-150s hold their value well, especially with lower-mileage examples. The 2016 2017 models are still in demand, making them easier to sell later.

7. **Towing and Payload Capacity**

- The **5.0L V8** models can tow up to **8,200 lbs** with the proper trailer hitch and cooling package, making them suitable for heavy loads.

- The **3.5L EcoBoost** can tow **5,500 7,700 lbs**, depending on configuration, while the **3.7L V6** maxes out around **5,000 lbs**.

8. **Available Safety Features**

- Many 2016 2017 F-150s come with **Ford Co-Pilot360** (blind-spot monitoring, rear cross-traffic alert, adaptive cruise control), improving safety over older models.

9. **Durable Frame and Suspension**

- The **high-strength steel frame** and **multi-link rear suspension** provide stability and durability, even with heavy loads.

10. **Aftermarket Support**

- The F-150 has a strong aftermarket presence, with parts and modifications available for performance, towing, and off-road use.

---

#### **Cons**

1. **Transmission and Drivetrain Issues (If Neglected)**

- The **6R80** can develop **slippage, rough shifting, or solenoid failures** if transmission fluid isn t changed regularly (every **60,000 100,000 miles**).

- **Torque converter failure** (common in high-mileage examples) can lead to **hard shifting or no engagement**, requiring a **$1,500 $2,500 replacement**.

- **Differential leaks** (especially in 4x4 models) are a common issue check for **gear oil leaks** under the truck.

2. **EcoBoost Engine Reliability Concerns**

- The **3.5L EcoBoost** is prone to **oil consumption** (burning oil) if not maintained properly. Some owners report **excessive oil burns** after **100,000 miles**, requiring frequent top-offs.

- **Turbocharger failures** can occur if the engine isn t properly cooled or maintained.

- **Carbon buildup** in intake valves may require a **carbon cleaning** ( $500 $800) around **100,000 miles**.

3. **5.0L V8 Weaknesses**

- **Valve cover gasket leaks** are a known issue, leading to **oil leaks and potential engine damage** if ignored.

- **Timing chain stretch** can cause **ticking noises** and reduced performance over time.

- **Head gasket failures** (though rare) can be catastrophic if they occur.

4. **Fuel Economy Limitations**

- The **3.5L EcoBoost** is better than the V8 but still **not great for highway driving** ( 14 16 MPG).

- The **3.7L V6** is the most fuel-efficient ( 20 MPG combined) but lacks power for heavy towing.

5. **Electrical and Infotainment Glitches**

- **SYNC 3** can have **software bugs**, freezing, or slow response.

- **Power window or door lock failures** are occasional issues, often requiring **reprogramming or part replacement**.

6. **Rust and Body Issues**

- **Underbody rust** is common in snowy or salted regions. Inspect the **wheel wells, frame rails, and rocker panels**.

- **Roof rack rust** (if equipped) can weaken structural integrity over time.

7. **High Maintenance Costs Over Time**

- While the F-150 is durable, **replacing the transmission, turbo, or engine components** can be expensive.

- **Suspension wear** (shocks, bushings) may need replacement after **100,000 miles**.

8. **Limited Off-Road Capability (Compared to Modern Models)**

- The **2016 2017 4x4 systems lack advanced off-road features** like **terrain management modes** or **locking rear differentials** (unless equipped with the **Off-Road Package**).

- **Lower ground clearance** (8.5 inches) makes it less capable than newer **F-150 Raptor** or **Super Crew** models.

9. **Recall and Warranty Issues**

- Some **2016 2017 models** had **recalls for transmission issues, fuel pump failures, or airbag defects**. Check **Ford s recall database** before purchasing.

10. **Higher Upfront Cost (Compared to Older Models)**

- While not as expensive as newer trucks, **2016 2017 F-150s with lower miles** can still be **$25,000 $40,000 **, depending on trim and condition.

---

### **Key Considerations Before Buying**

1. **Transmission Maintenance History**

- **Ask for service records** if the **6R80 fluid hasn t been changed**, expect **transmission issues** soon.

- **Listen for grinding or slipping** during test drives.

2. **Engine Condition**

- **3.5L EcoBoost:** Check for **oil leaks, turbo noise, or excessive smoke** (blue smoke burning oil).

- **5.0L V8:** Look for **oil leaks from valve covers, ticking noises (timing chain), or coolant mixing with oil**.

- **3.7L V6:** Generally reliable but check for **carbon buildup symptoms** (rough idle, reduced power).

3. **4x4 and Drivetrain Health**

- **Inspect for gear oil leaks** (common in 4x4 models).

- **Test the 4x4 engagement** does it lock smoothly, or is there **delay or grinding**?

4. **Body and Rust Inspection**

- **Check undercarriage, wheel wells, and frame** for rust.

- **Test all electrical components** (windows, locks, lights).

5. **Towing and Payload Capacity**

- If towing, ensure the **truck has the proper **towing package** (cooling, transmission cooler, etc.).

- **Weigh the load** exceeding limits can damage the drivetrain.

6. **Budget for Repairs**

- **Transmission rebuild ( $3,000 $5,000)**

- **Torque converter replacement ( $1,500 $2,500)**

- **Engine repairs (valve cover gaskets, timing chain, turbo $2
