2008 Infiniti EX35 Transmission Fluid Type Guide

Understanding Transmission Fluid for Your Infiniti EX35

When it comes to maintaining your 2008 Infiniti EX35, one of the most crucial aspects is ensuring that the transmission fluid is of the right type and quality. The transmission fluid plays a vital role in the smooth operation of your vehicle’s transmission system, affecting everything from shifting performance to overall longevity.

Manufacturer’s Recommendations

For the 2008 Infiniti EX35, the manufacturer specifies the use of Nissan Matic S transmission fluid. This fluid is specially formulated to meet the unique requirements of the EX35’s automatic transmission. Using the recommended fluid is essential for optimal performance and to avoid potential damage to the transmission.

Specifications of Nissan Matic S Transmission Fluid

Here are the key specifications and characteristics of Nissan Matic S transmission fluid:

Change Interval for Your Infiniti EX35 Transmission Fluid

Maintaining your 2008 Infiniti EX35 involves more than just regular oil changes; it also includes keeping an eye on your transmission fluid. Understanding the change interval for your transmission fluid is essential for ensuring the longevity and performance of your vehicle.

Recommended Change Intervals

The general consensus among automotive experts and manufacturers suggests that transmission fluid should be changed every 30,000 to 60,000 miles (approximately 48,000 to 96,000 kilometers). However, this can vary based on driving conditions and habits. Here are some factors to consider:

• Normal Driving Conditions: If you primarily drive under normal conditions, a change every 60,000 miles (96,000 km) is often sufficient.


• Severe Driving Conditions: If you frequently drive in heavy traffic, tow heavy loads, or operate in extreme temperatures, consider changing your fluid every 30,000 miles (48,000 km).


• Manufacturer Recommendations: Always refer to your owner’s manual for the manufacturer’s specific recommendations, as they may provide guidelines tailored to your vehicle’s needs.

Partial Transmission Oil Changes

In many cases, a full transmission fluid change can only be achieved by removing the transmission from the vehicle. This can be a labor-intensive and costly process. As a result, many owners opt for partial transmission oil 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 transmission service. Here are some points to consider:

• Fluid Exchange: Typically, a partial change will replace about 30-50% of the fluid, which can help refresh the fluid’s properties without the complexity of a full change.


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


• Frequency: Owners may choose to perform partial changes more frequently, such as every 15,000 to 20,000 miles (24,000 to 32,000 km), to keep the fluid in better condition.

Justification for Partial Changes

Statistical data and expert opinions support the practice of partial transmission fluid changes. According to the Automatic Transmission Rebuilders Association (ATRA), regular fluid maintenance is crucial for extending the life of a transmission. They recommend that even if a full change isn’t feasible, partial changes can significantly improve the fluid’s condition and, consequently, the transmission’s performance.

Additionally, a study published by the Society of Automotive Engineers (SAE) indicates that maintaining fluid quality through regular changes—whether full or partial—can reduce wear on internal components and improve overall efficiency. This is particularly important in modern vehicles, where transmission systems are more complex and sensitive to fluid degradation.

In summary, while the recommended change interval for your Infiniti EX35’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 and extend the life of your transmission.
