NISSAN CVT NS-3 Fluid (999MP-NS300P) OEM CVT Transmission Fluid – NS‑3 Formula, Factory Spec

NISSAN Genuine CVT NS-3 Fluid (999MP-NS300P) is the factory-original continuously variable transmission fluid engineered to preserve CVT shifting precision and protect drivetrain components.

NISSAN develops its genuine fluids to the same specifications as the vehicles they service: this NS-3 formula combines friction modifiers, low-temperature flow, and thermal stability to help a CVT perform as intended across temperature extremes. The product is the exact Original Equipment Manufacturer (OEM) fluid specified for Nissan and Infiniti CVT applications where NS-3 is required, and it’s recommended whenever a vehicle operator’s manual calls for this fluid type.

How does NISSAN CVT NS-3 fluid affect shifting performance?

NS-3 fluid is formulated to deliver stable friction characteristics so belt or chain engagement remains consistent, which helps maintain smooth, predictable acceleration and responsiveness. Its friction modifiers are balanced to reduce judder and chatter that can appear with incorrect or degraded fluids.

• Maintains consistent friction profile to reduce slip and shudder.
• Supports precise belt/chain engagement for smooth acceleration.
• Helps preserve factory shift calibration and response.

Why choose the genuine NISSAN OEM 999MP-NS300P instead of aftermarket CVT fluid?

Genuine NISSAN NS-3 is blended to the factory specification used during vehicle development and testing, ensuring compatibility with seals, clutch materials, and control systems. Aftermarket fluids may vary in additive concentration or viscosity, which can change hydraulic pressures and wear patterns in a CVT system.

• Matched to Nissan and Infiniti original design requirements.
• Reduces risk of seal swelling, slip, or premature wear caused by incompatible additives.
• Backed by manufacturer testing and the exact OEM formulation.

When should I replace my CVT fluid with NS-3, and what benefits will I notice?

Follow the service interval in your vehicle operator’s manual for recommended change frequency; many owners replace CVT fluid at scheduled maintenance or when diagnosing shift concerns. A proper NS-3 service can improve low-temperature shifting, restore smooth engagement, and support long-term component life by maintaining correct pressures.

• Change at manufacturer-recommended intervals or when servicing the transmission.
• Expect improved low-temperature shift feel and consistent operation.
• Helps maintain proper hydraulic pressure during hot-weather operation.

Is NS-3 fluid compatible with other makes and models?

NS-3 is specified for Nissan and Infiniti CVT systems requiring that formulation, and it may be acceptable for other makes if their manufacturer lists NS-3 as an approved fluid—always verify your vehicle’s manual or consult a dealer. Using the correct fluid type is critical to avoid negative effects on shift quality and component longevity.

• Designed primarily for Nissan and Infiniti CVTs that call for NS-3.
• Confirm compatibility via your vehicle manual or dealer before cross-using.
• Avoid substituting fluids with different additive packages or viscosities.

Who is this for: Owners and technicians who want the exact factory-specified CVT fluid for Nissan or Infiniti vehicles that require NS-3, and anyone servicing a CVT who prioritizes OEM compatibility. This part (999MP-NS300P) suits drivers wanting to maintain original shift behavior and protect transmission components with the same fluid used during vehicle development and testing.
