What type of transmission fluid does a Nissan Altima take?

The right transmission fluid depends on your Altima’s transmission type and model year. In short, CVT-equipped Altimas use Nissan’s CVT fluid (Matic CVT, NS-2/NS-3 variants as specified by your year), while traditional automatic Altimas use a Dexron-type ATF. Always verify with your owner's manual or a Nissan dealer for your specific vehicle.

Two main transmission types in the Altima

CVT-equipped Altimas

CVT systems require a dedicated CVT fluid rather than a conventional ATF. The exact NS (Nissan Specification) variant can vary by year, so check the manual for the precise specification. Below are the general guidelines you’ll encounter.

Before using or refilling, ensure you select the CVT fluid that matches your model year and Nissan specification (commonly NS-2 or NS-3). Do not substitute with standard automatic transmission fluid.



• Nissan CVT Fluid Matic CVT Fluid (typically NS-2/NS-3 variants as specified by your model year).


• Do not use conventional ATF in a CVT unless your manual explicitly allows it.

Using the correct CVT fluid helps maintain smooth shifting, proper cooling, and longevity of the transmission. Incorrect fluid can lead to slipping, reduced performance, or damage.

Traditional automatic Altimas

For Altimas with a conventional 4-speed automatic transmission, you’ll use a Dexron-type automatic transmission fluid. The exact specification can vary by year, so consult your owner's manual if you’re unsure.

Before selecting an ATF, confirm the exact Dexron specification your transmission requires (e.g., Dexron VI or Dexron II/III) as listed in your manual.



• Dexron VI Automatic Transmission Fluid (ATF) — commonly recommended for many modern Nissan automatics.


• Older manuals may specify Dexron II/III; if your manual calls for those, use the corresponding Dexron variant.


• Avoid using Mercon, Type-F, or other non-specified fluids unless explicitly approved by Nissan.

Choosing the correct ATF ensures proper shifting, lubrication, and cooling for non-CVT Altimas. If you’re replacing fluid in an older model, sticking to the exact specification in the manual is especially important.

How to confirm the right fluid for your Altima

Since transmission technology and specs evolve by model year, the safest approach is to:

Before purchasing or draining, reference your vehicle’s exact model year, transmission type, and the specification listed in the owner’s manual or on Nissan’s official service data.



• Check the owner’s manual under the maintenance/fluids section for the exact fluid specification.


• If you’re unsure, contact a Nissan dealer or certified technician for the correct fluid and specification for your VIN.

Correct identification of your transmission type and the proper specification helps prevent damage and preserves performance over time.

Summary

In summary, Altimas with a CVT use Nissan CVT Fluid Matic (NS-2/NS-3 as specified by year), while traditional automatics use a Dexron-type ATF (commonly Dexron VI, with older models possibly calling for Dexron II/III). Always verify the exact specification for your model year and transmission in the owner's manual or with a Nissan dealer before refilling.
