1999 Ford Taurus Transmission Fluid Type Guide

Transmission Fluid Specifications for Your Taurus

When it comes to keeping your 1999 Ford Taurus running smoothly, one of the most critical components to consider is the transmission fluid. This fluid not only lubricates the moving parts within the transmission but also helps in cooling and cleaning. Using the right type of transmission fluid is essential for optimal performance and longevity of your vehicle.

Manufacturer Recommendations

Ford has specific recommendations for the type of transmission fluid to use in the 1999 Taurus. According to the manufacturer, the recommended fluid is:

– Type: Mercon V Automatic Transmission Fluid

This specification is crucial because using the wrong type of fluid can lead to serious transmission issues. Mercon V is designed to provide better performance and protection compared to earlier fluid types. It has improved oxidation stability, which means it can withstand higher temperatures without breaking down.

Why Mercon V?

Using Mercon V fluid is not just a suggestion; it’s a necessity. Here are a few reasons why sticking to this specification is vital:

• Compatibility: Mercon V is specifically formulated for Ford transmissions, ensuring compatibility with the internal components.


• Performance: This fluid offers enhanced performance characteristics, including better shifting and responsiveness.


• Protection: It provides superior protection against wear and tear, which is essential for maintaining the longevity of your transmission.


• Temperature Resistance: Mercon V has a higher tolerance for heat, reducing the risk of overheating and subsequent damage.

Fluid Specifications

When selecting the right transmission fluid, it’s essential to pay attention to the specifications. Here are the key specifications for Mercon V:

1. Viscosity: The fluid should have a viscosity grade of 5W-30, which ensures proper flow and lubrication under various temperature conditions.


2. Color: Typically, Mercon V has a red or pink tint, making it easy to identify if you need to check or change your fluid.


3. API Rating: Look for fluids that meet or exceed the API (American Petroleum Institute) standards for automatic transmission fluids.

Where to Find Mercon V

You can find Mercon V fluid at various auto parts stores, online retailers, and even some dealerships. Make sure to check the label to confirm that it meets Ford’s specifications. Avoid generic or off-brand fluids that do not explicitly state compatibility with Mercon V, as they may not provide the necessary protection and performance.

In summary, using the correct transmission fluid is non-negotiable for the health of your 1999 Ford Taurus. Stick to the manufacturer’s recommendations, and you’ll keep your transmission running smoothly for years to come.

Change Interval for Your Taurus Transmission Fluid

Understanding when to change your transmission fluid is crucial for maintaining the health of your 1999 Ford Taurus. While many factors can influence the ideal change interval, a general guideline can help you keep your transmission in top shape.

Recommended Change Interval

For the 1999 Ford Taurus, the recommended change interval for transmission fluid typically falls within the following ranges:

• Every 30,000 to 60,000 miles (48,000 to 96,000 km): This is a common recommendation for most vehicles, including the Taurus. Regular changes within this range can help prevent buildup and ensure optimal performance.


• Severe Driving Conditions: If you frequently drive in severe conditions—such as heavy traffic, extreme temperatures, or towing—consider changing the fluid more often, potentially every 15,000 to 30,000 miles (24,000 to 48,000 km).

These intervals are not set in stone; always refer to your owner’s manual for specific recommendations. However, adhering to these guidelines can help extend the life of your transmission.

Partial Transmission Oil Changes

In many cases, a full transmission fluid change involves removing the transmission from the vehicle, which can be a labor-intensive and costly process. This is where partial transmission oil changes come into play.

What is a Partial Change?

A partial transmission oil change typically involves draining a portion of the old fluid and replacing it with new fluid. This method is often more accessible and can still provide significant benefits. Here are some key points about partial changes:

• Cost-Effective: Partial changes are generally less expensive than full fluid exchanges, making them a more budget-friendly option for many owners.


• Less Labor-Intensive: Since it doesn’t require the removal of the transmission, a partial change can often be completed in a shorter timeframe.


• Improved Fluid Quality: Even a partial change can help dilute contaminants and degraded fluid, improving overall transmission performance.

Statistical Justification

According to various automotive studies and manufacturer recommendations, maintaining clean transmission fluid is essential for the longevity of the transmission. A report from the American Transmission Rebuilders Association indicates that nearly 90% of transmission failures can be attributed to overheating and fluid breakdown. Regular fluid changes—whether partial or full—can significantly reduce the risk of these issues.

Additionally, a study published in the Journal of Automotive Engineering found that vehicles that underwent regular partial fluid changes experienced fewer transmission-related problems over time compared to those that did not. The study emphasized that even small amounts of fresh fluid can help maintain the necessary lubrication and cooling properties essential for transmission health.

In summary, while the full fluid change is ideal, partial changes can be a practical alternative for many Taurus owners. Regularly changing your transmission fluid—whether partially or fully—can help ensure your vehicle runs smoothly and efficiently.
