Understanding Transmission Fluid for Your Infiniti G37

When it comes to keeping your Infiniti G37 running smoothly, understanding the right transmission fluid is crucial. The transmission fluid plays a vital role in lubricating the moving parts of your vehicle’s transmission, ensuring smooth gear shifts, and preventing overheating. Here’s what you need to know about the transmission fluid for your G37.

Manufacturer’s Recommendations

Infiniti recommends using a specific type of transmission fluid for the G37 to maintain optimal performance. The correct fluid type is Nissan Matic S or Nissan Matic J. These fluids are formulated to meet the unique requirements of the G37’s automatic transmission system.

Specifications of Nissan Matic S and J

Here are the key specifications for the recommended transmission fluids:

Change Interval for Your Infiniti G37 Transmission Fluid

Maintaining your Infiniti G37’s transmission fluid is crucial for the longevity and performance of your vehicle. Knowing when to change the fluid can save you from costly repairs down the line.

Recommended Change Intervals

For the 2008 Infiniti G37, the general recommendation for changing the transmission fluid is every 60,000 to 100,000 miles (approximately 96,000 to 160,000 kilometers). However, this can vary based on driving conditions and habits. Here are some factors to consider:

• Driving Conditions: If you frequently drive in stop-and-go traffic, tow heavy loads, or operate in extreme temperatures, you may need to change the fluid more often.
• Fluid Condition: Regularly checking the condition of your transmission fluid can help determine if it needs changing sooner. Look for discoloration or a burnt smell, which are indicators that the fluid is breaking down.
• Manufacturer Guidelines: Always refer to your owner’s manual for specific recommendations, as manufacturers may update their guidelines based on new data.

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 fluid change typically involves draining a portion of the old fluid and replacing it with new fluid. This method is often more accessible and can be performed without extensive disassembly of the vehicle.

Benefits of Partial Changes

There are several advantages to opting for a partial transmission fluid change:

1. Cost-Effective: Partial changes are generally less expensive than full fluid changes, making them a more budget-friendly option for regular maintenance.
2. Less Downtime: Since partial changes require less labor, your vehicle can be back on the road much quicker.
3. Improved Fluid Quality: Regular partial changes can help maintain the overall quality of the transmission fluid, reducing the buildup of contaminants over time.

Statistical Data and Authoritative Sources

According to the Automatic Transmission Service Group (ATSG), regular maintenance, including fluid changes, can significantly extend the life of your transmission. Their studies indicate that vehicles with regular fluid changes experience fewer transmission failures and repairs.

Additionally, a report from the National Institute for Automotive Service Excellence (ASE) states that neglecting transmission fluid changes can lead to overheating and increased wear on internal components. This reinforces the importance of adhering to recommended change intervals, whether through partial or full fluid changes.

In summary, understanding the change intervals for your Infiniti G37’s transmission fluid and considering partial changes can help you maintain your vehicle’s performance and longevity. Regular maintenance is key to avoiding costly repairs and ensuring smooth operation.
