The Lincoln Navigator L is a luxury full-size SUV that serves as one of the flagships in Lincoln’s vehicle lineup. The “L” in Navigator L signifies the extended-length version, offering more cargo space and legroom, perfect for those who need extra space without sacrificing luxury and performance.
This model has gone through various generations, each improving upon the last in terms of technology, comfort, and driving dynamics. Over the years, the Navigator L has become synonymous with opulence, and it competes directly with other luxury SUVs in the market.
Transmission fluid plays a crucial role in keeping your Navigator L’s transmission system running smoothly. This fluid serves as both a lubricant and a coolant for the transmission’s moving parts. It’s essential for transferring power from the engine to the wheels, affecting your vehicle’s performance and longevity.
Key Takeaways:
- Follow Manufacturer Guidelines: For optimal performance and longevity of your Lincoln Navigator L’s transmission, it’s crucial to use the manufacturer-recommended transmission fluid.
- Transmission Fluid Capacities: Between 11.1 and 13.1 quarts.
- Watch for Symptoms: Pay attention to signs of aging transmission fluid like slipping gears or darkened fluid color to know when it’s time for a change.
- Cost Implications: While costs can vary, it’s generally more affordable in the long run to stick with recommended fluids and routine changes to avoid pricier repairs later.
- Variable Change Intervals: The lifespan of your transmission fluid can be affected by your driving conditions, so it’s important to consult your manufacturer’s guidelines for change intervals.
- DIY Risks: While changing the transmission fluid yourself might seem tempting, using non-recommended fluids can void your warranty and lead to higher repair costs in the future.
Failure to maintain the correct transmission fluid level or using the wrong type of fluid can result in reduced fuel efficiency, and poor performance, and may even lead to severe transmission damage requiring costly repairs.
Therefore, understanding your vehicle’s transmission fluid capacity, the right type of fluid to use, and when to change it is indispensable for the optimal performance and long life of your Lincoln Navigator L.
2007-2017 Lincoln Navigator L Transmission Fluid Capacity And Transmission Fluid Type
For the 3rd Generation Lincoln Navigator L models produced between 2007 and 2017, the transmission fluid capacity is generally around 11-13 quarts for a full flush.
| Gearbox | Fluid capacity | Fluid type |
|---|---|---|
| 6-speed 6HP26 automatic | Total fill: 11.1 quarts (10.5 liters) Initial fill: 5 quarts (4.7 liters) | Mercon SP |
| 6-speed 6R75 automatic | Total fill: 11.1 quarts (10.5 liters) | Mercon SP |
| 2010 6-speed 6R80 automatic | Total fill: 13.1 quarts (12.4 liters) Initial fill: 3.5 quarts (3.3 liters) | Mercon LV |
The recommended transmission fluid for this generation is Mercon SP Automatic Transmission Fluid. Make sure to always use the manufacturer-recommended fluid to ensure optimal performance.
Lincoln suggests changing the transmission fluid every 60,000 miles for these models under normal driving conditions. However, if you’re using your Navigator L for towing or driving in extreme conditions, it’s advisable to shorten that interval to around 30,000 miles.
2018-Now Lincoln Navigator L Transmission Fluid Capacity And Transmission Fluid Type
For the 4th Generation Lincoln Navigator L models built between 2018 and 2021, the transmission fluid capacity is generally around 13 quarts for a complete flush.
| Gearbox | Fluid capacity | Fluid type |
|---|---|---|
| 10-speed 10R80 automatic | Total fill: 13 quarts (12.3 liters) | Mercon ULV |
The recommended transmission fluid for this generation is the Mercon ULV Automatic Transmission Fluid. Always ensure to use the manufacturer-specified fluid to maintain optimal vehicle performance.
Lincoln recommends a transmission fluid change every 60,000 miles for normal driving conditions. If your Navigator L sees heavy use, such as towing or off-road driving, it’s advisable to change the fluid more frequently, approximately every 30,000 miles.
Signs Your Transmission Fluid Needs Changing
It’s important to know the signs that indicate your Lincoln Navigator L’s transmission fluid needs changing. Here are some symptoms to watch out for:
- Slipping Gears: If your Navigator L’s transmission unexpectedly changes gears or has difficulty staying in gear, this could be a sign of low or deteriorated transmission fluid.
- Delayed or Rough Shifts: Experiencing jolts or delays when the vehicle is shifting gears might indicate that the transmission fluid is old or insufficient.
- Transmission Overheating: Overheating is often an indicator of low transmission fluid. Overheating can lead to more serious issues, including total transmission failure.
- Unexplained Noises: Hearing grinding or whining noises from the area of the transmission when your vehicle is in neutral could suggest that your transmission fluid needs to be changed.
- Check Engine Light: Although not exclusive to transmission issues, a lit check engine light can sometimes indicate problems with the transmission fluid or the transmission itself.
Appearance of Old vs. New Fluid
- New Fluid: New transmission fluid is usually translucent with a bright red color. It has a slightly sweet or tart odor.
- Old Fluid: Worn-out or old transmission fluid turns darker, usually a dark brown or even black, and may contain metal particles. The smell becomes burnt and unpleasant.
It’s advisable to check the transmission fluid regularly, both its level and its quality. If it appears darkened or smells burnt, it’s time for a change.
Cost of Transmission Fluid Change
The cost to change the transmission fluid on a Lincoln Navigator L can vary depending on a few different factors. However, on average, you can expect to pay between $100 and $250 for a professional service. This typically includes the cost of the new fluid and the labor involved in draining and refilling the transmission system.
Factors Affecting the Cost
Several variables can influence the overall cost of a transmission fluid change for your Navigator L:
- Location: Labor costs can fluctuate depending on your geographical location. Rates tend to be higher in larger cities.
- Dealership vs. Independent Mechanic: Service from a dealership is generally more expensive than that from an independent mechanic, though a dealership might offer specialized expertise.
- Type of Fluid: Premium, manufacturer-recommended fluid types may cost more than generic or multi-use fluids.
- Additional Services: Sometimes, the transmission system may require flushing or cleaning, which would add to the overall cost.
- Vehicle Condition: If your transmission has problems that require additional parts or labor, these would naturally raise the cost.
- Labor Rates: Different mechanics or service centers have varying labor rates, which can affect the final cost.
Benefits of Using the Recommended Fluid Types
Adhering to manufacturer specifications is crucial when it comes to changing your Lincoln Navigator L’s transmission fluid. Here’s why:
- Optimized Performance: Manufacturer-recommended fluids are specifically designed to complement your vehicle’s transmission, thus optimizing performance.
- Longevity: Using the correct type of transmission fluid can extend the lifespan of your vehicle’s transmission, reducing the risk of costly repairs in the long term.
- Warranty Protection: Using non-recommended fluids can void your vehicle’s warranty, leaving you to foot the bill for any related repairs.
