The 1998 Ford Explorer is equipped with either a 4R55E or a 5R55E automatic transmission. Both of these transmissions require specific types of fluid to function correctly. According to Ford’s specifications, the recommended transmission fluid for these models is:
- Mercon V Automatic Transmission Fluid
Using the correct type of fluid is essential for several reasons:
1. Performance
Using Mercon V ensures that your transmission operates smoothly and efficiently. This fluid is designed to provide the right level of lubrication, cooling, and cleaning for the internal components of the transmission.
2. Compatibility
Mercon V is formulated to be compatible with the materials used in the 1998 Explorer’s transmission. Using a different type of fluid can lead to issues such as seal deterioration, which can cause leaks and ultimately lead to transmission failure.
3. Warranty Considerations
If your vehicle is still under warranty, using the recommended fluid is crucial. Using an incorrect fluid type can void your warranty and lead to costly repairs down the line.
Fluid Specifications
It’s not just about the type of fluid; the specifications matter too. Here are the key specifications for Mercon V:
- Viscosity: Mercon V has a viscosity rating that ensures proper flow and lubrication at various temperatures.
- Additives: This fluid contains specific additives that help in reducing friction, preventing wear, and maintaining cleanliness within the transmission.
- Thermal Stability: Mercon V is designed to withstand high temperatures, which is crucial for maintaining performance during heavy-duty driving conditions.
Why You Shouldn’t Skimp on Quality
It’s tempting to save a few bucks by using a cheaper or generic fluid, but this can be a costly mistake. Here’s why you should stick to the manufacturer’s recommendations:
- Long-Term Costs: While you might save money upfront, using the wrong fluid can lead to premature wear and tear, resulting in expensive repairs.
- Performance Issues: Incorrect fluid can lead to shifting problems, overheating, and even complete transmission failure.
- Resale Value: A well-maintained vehicle with the correct fluids will hold its value better than one that has been improperly cared for.
In summary, using the correct transmission fluid type for your 1998 Ford Explorer is non-negotiable. Stick to Mercon V, follow the specifications, and you’ll keep your transmission running smoothly for years to come.

Change Interval for Transmission Fluid
Maintaining your 1998 Ford Explorer’s transmission fluid is crucial for ensuring the longevity and performance of your vehicle. The change interval for transmission fluid can vary based on driving conditions, but general guidelines suggest changing the fluid every 30,000 to 60,000 miles (48,000 to 96,000 kilometers). However, this can depend on several factors.
Recommended Change Intervals
- Normal Driving Conditions: If you primarily drive in normal conditions (highway driving, moderate temperatures), changing the fluid every 30,000 to 60,000 miles is typically sufficient.
- Severe Driving Conditions: If you often drive in severe conditions (stop-and-go traffic, towing, extreme temperatures), consider changing the fluid more frequently, around every 30,000 miles (48,000 kilometers).
Why Change Transmission Fluid?
Transmission fluid serves multiple purposes, including lubrication, cooling, and cleaning. Over time, it can become contaminated with debris, metal shavings, and other particles. This contamination can lead to:
- Increased Wear: Old fluid loses its effectiveness, leading to increased friction and wear on transmission components.
- Overheating: Contaminated fluid can cause the transmission to overheat, resulting in potential damage.
- Shifting Issues: Old or contaminated fluid can lead to rough or delayed shifting, affecting drivability.
Partial Transmission Oil Changes
In many cases, a complete transmission fluid change requires removing the transmission from the vehicle, making it a labor-intensive and costly process. Because of this, many owners opt for partial transmission fluid changes, which can be performed more easily and frequently.
What is a Partial Transmission Oil Change?
A partial transmission oil change involves draining a portion of the old fluid and replacing it with new fluid. This method can help maintain fluid quality without the need for a complete fluid exchange.
Benefits of Partial Changes
- Cost-Effective: Partial changes are generally less expensive than full fluid exchanges, making them more accessible for regular maintenance.
- Less Labor-Intensive: This method requires less time and effort, allowing for quicker service.
- Regular Maintenance: Performing partial changes more frequently can help keep the transmission fluid cleaner and more effective.
Statistical Justification
According to various automotive maintenance studies, regular fluid changes—whether partial or full—can significantly extend the life of a transmission. A study by the Automotive Research Association found that vehicles that underwent regular fluid changes experienced a 30% lower failure rate compared to those that did not maintain their fluid.
Additionally, the National Institute for Automotive Service Excellence (ASE) recommends that vehicle owners regularly check and change their transmission fluid to prevent costly repairs. They emphasize that even partial changes can contribute to maintaining fluid quality and overall transmission health.
In summary, while the recommended change interval for your 1998 Ford Explorer’s transmission fluid is generally between 30,000 to 60,000 miles, opting for partial changes can be a practical and effective way to maintain fluid quality without the need for a full fluid exchange. Regular maintenance, whether through partial or full changes, is essential for ensuring the longevity and performance of your vehicle’s transmission.
