The 2014 Ford Taurus requires Mercon LV automatic transmission fluid. Use Motorcraft Mercon LV ATF or another fluid that clearly meets Ford’s Mercon LV specification.
Understanding the specification
Ford shifted to Mercon LV for many of its newer six-speed transmissions around the late 2000s and into the 2010s. The Taurus models from 2014 use a modern six-speed automatic, which is designed to operate with Mercon LV fluid. Using a fluid that does not meet this specification can affect shifting quality and may impact warranty coverage.
What is Mercon LV and why it matters
Mercon LV is Ford’s low-viscosity automatic transmission fluid designed for newer transmissions. It provides smooth shifting, proper hydraulic control, and protection of internal components. When servicing a Taurus transmission, it’s important to choose a fluid that explicitly states Mercon LV on the bottle.
What to buy
Before you buy, verify that the bottle explicitly states that it meets Ford Mercon LV specification. The list below covers the typical, recommended options.
- Motorcraft Mercon LV ATF (Ford’s official fluid)
- Any ATF that clearly meets Ford Mercon LV specification (check the label for “Mercon LV”)
- Environmentally equivalent aftermarket fluids labeled Mercon LV and suitable for Ford six-speed transmissions
Use the correct fluid and avoid fluids labeled for older Ford specs (such as Mercon V) or other brands that do not advertise Mercon LV compatibility. Always confirm the specification on the bottle before purchasing.
Maintenance notes and service considerations
The Taurus transmission fluid should be changed according to Ford’s recommended maintenance schedule, which is typically every 60,000 miles or as specified in the owner's manual under normal driving conditions. Some owners opt for drain-and-fill services, while others may pursue a more complete flush. If you’re unsure, have a qualified technician perform the service to ensure the correct procedure and fluid volume.
- Confirm the vehicle’s exact transmission model and drive configuration (FWD vs. AWD) because service procedures can vary slightly.
- Use the specified Mercon LV fluid and a properly calibrated filling procedure to avoid overfilling or underfilling.
- Replace the transmission filter if your service includes a pan drop; some models with a filter may not have a serviceable filter in every year.
- Check for any service bulletins or recalls related to transmission fluid or shifting behavior that could affect your vehicle.
- Test drive after service to confirm smooth shifting and verify there are no leaks or abnormal noises.
Professional service is recommended if you are upgrading or flushing the transmission, as improper flushing can cause debris to lodge in the valve body or solenoids.
Common questions
If in doubt, consult your owner’s manual or a Ford dealer to confirm the exact fluid specification for your specific Taurus model and drivetrain. The guidance above applies to the common configurations of the 2014 Taurus with a modern six-speed automatic transmission.
Summary
For a 2014 Ford Taurus, the correct transmission fluid is Mercon LV. Use Motorcraft Mercon LV ATF or another product that clearly meets Ford Mercon LV specifications. Always verify the label, follow Ford’s service intervals, and consider professional service for a proper drain-and-fill or flush to maintain optimal transmission performance.
