Change Interval for Transmission Fluid
Maintaining your 2008 Infiniti M35 involves more than just regular oil changes; the transmission fluid also requires attention. The change interval for transmission fluid can vary based on driving conditions and habits, but a general guideline is to change the fluid every 30,000 to 60,000 miles (approximately 48,000 to 96,000 kilometers).
Manufacturer Recommendations
While the manufacturer may provide a specific interval, many automotive experts suggest that more frequent changes can be beneficial, especially for vehicles that experience heavy use or harsh driving conditions.
- Normal Driving Conditions: 30,000 to 60,000 miles
- Severe Driving Conditions: 15,000 to 30,000 miles
Severe conditions include frequent stop-and-go traffic, towing, or driving in extreme temperatures. In these cases, changing the fluid more often can help prevent premature wear and maintain optimal performance.
Partial Transmission Oil Changes
One important aspect to consider is that in many cases, a full transmission fluid change is not feasible without removing the transmission from the vehicle. This is due to the design of most automatic transmissions, which do not have a simple drain plug like an engine oil pan.
Why Partial Changes Are Common
Partial transmission fluid changes, often referred to as “drain and fill,” involve removing a portion of the old fluid and replacing it with new fluid. This method is more practical and can still provide significant benefits.
- Easier Access: It allows for fluid replacement without the need for extensive labor or equipment.
- Cost-Effective: A partial change is generally less expensive than a full fluid exchange.
- Maintains Fluid Quality: Regular partial changes can help maintain the overall quality of the transmission fluid.
Statistical Data and Authoritative Sources
According to the Automatic Transmission Rebuilders Association (ATRA), regular maintenance, including fluid changes, can significantly extend the life of a transmission. They recommend that vehicle owners adhere to the change intervals and consider partial changes as a viable option for maintaining fluid quality.
- Fluid Degradation: Transmission fluid can degrade over time due to heat and contaminants. Regular changes help mitigate this degradation.
- Preventive Maintenance: Statistics show that vehicles with regularly changed transmission fluid are less likely to experience transmission failure.
- Owner Feedback: Many owners report improved shifting and overall performance after implementing a regular partial change schedule.
In summary, while the full transmission fluid change may not always be possible without significant work, regular partial changes can help maintain the health of your 2008 Infiniti M35’s transmission. Keeping an eye on the change intervals and opting for partial changes when necessary can lead to a smoother driving experience and a longer-lasting transmission.
