Answer: It uses a five-speed automatic transmission (Ford 5R55S) paired with the 5.4-liter V8. The 2007 Navigator is offered in rear-wheel drive or four-wheel drive, with the same five-speed automatic connected to a transfer case in 4WD models.
The Lincoln Navigator, a full-size SUV from Ford’s luxury division, shares its drivetrain lineage with Ford’s Expedition and other large SUVs of the era. For the 2007 model year, the focus is on a robust, traditional automatic transmission designed to handle substantial torque from the 5.4L V8 while delivering ease of use and reliability for family and towing duties. Below is a breakdown of what that means in practice and how to verify it on a given vehicle.
Transmission specifics
Below are the core details you’re most likely to encounter when looking at a 2007 Navigator’s gearbox and how it fits into the vehicle’s overall drivetrain configuration.
- Transmission type: automatic
- Transmission model: Ford 5R55S (five-speed automatic)
- Engine pairing: 5.4L V8
- Drive configurations: rear-wheel drive (RWD) or four-wheel drive (4WD) with an accompanying transfer case for the 4WD system
Before listing, note that the 2007 Navigator uses a conventional automatic transmission rather than a manual or CVT. The following points summarize the main aspects of that transmission setup.
The 5R55S is a widely used Ford transmission in the mid-2000s, pairing well with the Navigator’s heavy-duty V8 and its towing capabilities. In 4WD models, the transmission remains the same, with the transfer case providing the necessary low-range and front axle engagement as needed.
Variant details by drivetrain
Rear-wheel drive vs. four-wheel drive
Both RWD and 4WD Navigator configurations share the same five-speed automatic transmission, but the 4WD version adds a transfer case and, depending on the model year and equipment, may include additional gearing options for off-road or low-traction conditions. The gearbox itself remains a five-speed unit designed to handle the engine’s torque output.
When evaluating a used 2007 Navigator, confirm whether the vehicle is equipped with RWD or 4WD, but expect the transmission to be the same 5R55S five-speed automatic in either case.
Maintenance and troubleshooting
Routine maintenance and early troubleshooting can help extend transmission life and prevent common issues. The following guidance is relevant to the 5R55S-equipped Navigator.
- Fluid service: follow a documented maintenance schedule for automatic transmission fluid (ATF) changes as recommended by Ford for this era, typically at multi-year or mileage intervals depending on usage
- Warning signs: watch for slipping, hard or delayed shifting, transmission hesitation, or unusual noises, which warrant a professional scan and fluid inspection
- Diagnostics: if transmission trouble codes appear, a qualified technician can check for sensor, solenoid, valve body, or wear-related issues and advise on repair or replacement
Before listing, a quick note on upkeep and warning signs helps owners stay ahead of problems.
With proper service, the 5R55S-equipped Navigator can deliver durable performance consistent with its mission as a large, capable luxury SUV.
Identification and verification
How to confirm the transmission in your specific vehicle
To verify the exact transmission on a given 2007 Navigator, check the emission or vehicle service label under the hood, consult the VIN, or refer to the original window sticker or service manual. Dealers and trusted repair shops can also decode the VIN to confirm the transmission model code (5R55S) and the drivetrain configuration.
Summary
For the 2007 Lincoln Navigator, the typical transmission is a five-speed automatic (Ford 5R55S) paired with the 5.4L V8, available in rear-wheel drive or four-wheel drive. This setup reflects Ford’s mid-2000s approach to large SUV drivetrains, prioritizing reliability and familiar operation. Verifying the drivetrain and transmission via VIN or service records can help ensure you’re working with the correct specifications for your specific vehicle.
