2014-2017 Infiniti QX70 Transmission Fluid Capacity And Transmission Fluid Type

The transmission fluid capacity refers to the volume of fluid your vehicle’s transmission can hold. It’s crucial to ensure the correct amount of fluid, as both overfilling and underfilling can lead to transmission problems.

The Infiniti QX70 uses a 7-speed automatic transmission across all models, which typically holds between 9.7 and 10 quarts of transmission fluid. However, the specific capacities can vary slightly between different model years.

For the Infiniti QX70 models produced between 2014 and 2016, the 7-speed automatic transmission has a total fluid capacity of approximately 9.7 quarts. However, please note that this is the total system capacity, which includes the transmission, torque converter, and cooling lines.

During a standard transmission fluid change, where the fluid is not drained from the torque converter or cooling lines, approximately 5 to 6 quarts will typically be replaced.

The facelifted 2017 model maintains the same transmission specifications as the previous models. Thus, it shares the same total fluid capacity of approximately 9.7 quarts. During a typical transmission fluid change, about 5 to 6 quarts of fluid will be replaced.

The type of transmission fluid you use in your Infiniti QX70 can significantly impact its performance and longevity. Using the correct fluid can help ensure smooth gear shifting, prevent overheating, and extend your vehicle’s lifespan.

Infiniti recommends using Nissan Matic-S automatic transmission fluid in the QX70’s 7-speed automatic transmission. This fluid has been specifically designed to offer optimal performance and protection for Nissan and Infiniti vehicles. It offers excellent lubrication and cooling properties, and it’s compatible with the materials in the transmission, preventing premature wear and tear.

While it’s generally best to use the manufacturer’s recommended transmission fluid, there may be situations where a suitable alternative is required. In such cases, you can consider high-quality automatic transmission fluids that meet or exceed the JASO-1A performance standard, which the Nissan Matic-S fluid also meets.

Some suitable alternatives include Idemitsu ATF Type S, Valvoline MaxLife ATF, Royal Purple 01320 Max ATF, and Castrol Transmax ATF/CVT Universal. These alternatives are widely available and have been reported to work well in Nissan and Infiniti vehicles.

However, always ensure to cross-check the compatibility with your specific vehicle model and the fluid requirements before using an alternative transmission fluid. The most accurate information can often be found in your vehicle’s owner’s manual or by consulting with a trusted automotive professional.

Infiniti QX70 Optimal Change Intervals

Knowing when to change your transmission fluid is equally as important as knowing the right fluid type to use. Regularly replacing your transmission fluid can ensure your vehicle’s transmission continues to operate smoothly and can significantly extend its lifespan.

For the Infiniti QX70, Infiniti recommends changing the automatic transmission fluid every 60,000 miles under normal driving conditions. However, if the vehicle is frequently driven under severe conditions, such as towing heavy loads, driving in dusty conditions, or frequent stop-and-go traffic, the fluid should be replaced more frequently – approximately every 30,000 miles.

Factors Affecting Change Intervals

Several factors can affect how frequently you should change your transmission fluid. Some of these factors include:

  1. Driving Conditions: As mentioned above, if your vehicle frequently operates under severe conditions, such as towing heavy loads, off-roading, or stop-and-go traffic, you may need to change your transmission fluid more often.
  2. Transmission Fluid Quality: Higher quality fluids may last longer and perform better over time, potentially extending the time between fluid changes.
  3. Vehicle Usage: If the vehicle is used more often, the transmission fluid will likely need to be replaced more frequently. Similarly, a vehicle that is rarely used may also require more frequent fluid changes, as the fluid can degrade over time, even if the vehicle is not in use.
  4. Transmission Health: If the transmission has any existing issues or damage, more frequent fluid changes may be necessary to prevent further damage and maintain the transmission’s performance.

In any case, regular inspection of the transmission fluid condition is vital. If the fluid appears burnt or dirty, it should be replaced regardless of mileage. The cost of changing the transmission fluid is a small investment compared to the cost of repairing or replacing a damaged transmission.
