The Infiniti QX56 typically requires Nissan’s ATF Matic D (often listed as Matic D or Nissan Matic D) for its automatic transmission. Always confirm the exact specification for your Vehicle Identification Number (VIN) in the owner's manual or with a dealership.
Understanding the QX56 transmission and fluid requirements
The QX56, depending on year and drivetrain configuration, uses a 5-speed automatic transmission commonly identified as RE5R05A in many model years. The manufacturer’s guidance for this transmission is to use ATF Matic D, a fluid formulated specifically for this family of automatic transmissions. Using the specified fluid helps ensure smooth shifting, proper hydraulic pressure, and longevity of the transmission.
To avoid ambiguity, researchers and owners should reference the official service data for their exact VIN. Specifications can vary slightly by production run or regional market, so checking the manual or contacting Infiniti Support is prudent if you’re unsure.
For quick reference, here are the typical fluid expectations tied to the QX56’s common transmission setup.
- 2004–2010 Infiniti QX56 with the RE5R05A 5-speed automatic: ATF Matic D (Nissan Matic D) is the recommended fluid.
- 2011–2013 Infiniti QX56 (same or similar transmission): ATF Matic D remains the standard specification per official guidance.
Always verify with your manual or an Infiniti/Nissan dealer using your VIN to confirm which specification applies to your exact vehicle.
How to confirm the right fluid for your VIN
Look up your vehicle’s exact fluid specification in the owner’s manual or service bulletin for your production year. If you don’t have access to the manual, contact an Infiniti dealership with your VIN—they can retrieve the precise specification and offer an approved fluid source.
Practical notes on sourcing and substitutions
When shopping for ATF, search for “ATF Matic D” or “Nissan Matic D.” Do not substitute with fluids that aren’t specified for the QX56’s transmission, as using the wrong fluid can affect shifting performance and long-term reliability. If Matic D is temporarily unavailable, a dealer can advise on an approved interim option or a supplier that carries the exact specification.
Maintenance considerations and tips
Regular maintenance, including periodic fluid and filter service as per Infiniti’s schedule, helps preserve transmission performance. If you’re performing a DIY drain and fill, ensure the engine is warm, follow correct fill procedures, and dispose of old fluid at an authorized collection point.
When in doubt, err on the side of caution and have a certified technician verify the correct fluid type for your specific QX56 model and VIN before proceeding with a service.
Summary
For the Infiniti QX56, the standard transmission fluid is Nissan/Infiniti ATF Matic D. While the exact requirement can vary by year or VIN, Matic D remains the baseline specification for most RE5R05A-equipped QX56 models. Always confirm with the owner’s manual or a dealership to ensure you use the correct fluid for your vehicle, and consult a professional if you’re uncertain.
