| Brand | Name | ||
|---|---|---|---|
| Nissan | Nissan Genuine OEM CVT-3 Transmission Fluid (NS-3) | NS-3 / OEM-Grade | Original equipment performance for Nissan/Infiniti |
| Castrol | Transmax ATF/CVT Universal | ATF/CVT Universal | Broad compatibility; high-temperature protection |
| Valvoline | CVT Full Synthetic | CVT Fluid | Enhanced anti-shudder; durable formulation |
| Nissan | Nissan NS3 Transmission Fluid – 6 Quarts | NS-3 / OEM | Engineered for Nissan transmissions |
| Triax | TRIAX CVT ATF OEM Grade | CVT OEM Grade | Universal CVT compatibility; strong shift quality |
What to consider when selecting CVT fluid:
– Compatibility: Ensure the fluid meets your vehicle’s CVT specification (NS-2, NS-3, SB2, etc.).
– Driving conditions: Harsh climates, towing, or city driving may benefit from higher temperature stability and anti-shudder properties.
– Synthetic vs mineral blends: Synthetic CVT fluids typically offer broader temperature range and longer life.
– Maintenance interval: Some CVTs require specific top-off or complete fluid changes at set intervals.
– Manufacturer recommendations: Always reference your owner’s manual for exact fluid spec and capacity.
Nissan Genuine OEM CVT-3 Transmission Fluid
The exact original equipment manufacturer fluid that your vehicle came with; use where Nissan CVT NS-3 fluids are required in Nissan, Infiniti, and other make vehicles. Its unique formulation uses high-quality friction modifiers and additives to ensure stable, precise operation, with superior low-temperature fluidity for smoother shifting and proper pressure in hot weather.
Castrol Transmax ATF/CVT Universal
Designed for most automatic and continuously variable transmissions, including Ford, GM, Chrysler, and Asian imports. Offers enhanced friction durability for smooth transmission performance and superior high-temperature protection to resist oxidation, helping maintain transmission efficiency across diverse driving conditions.
Valvoline CVT Full Synthetic
Meets the demands of most belt and chain-driven CVTs, providing smooth shifting and power transfer with anti-shudder protection. Anti-wear technology improves durability and helps extend the life of the transmission by maintaining protective lubricating films under stress.
Nissan GenuineNS3 Transmission Fluid – 6 Quarts
Synthetic and mineral blend to ensure smooth transmission operation and enhanced durability. Six quarts is ideal for a full transmission fluid change in most Nissan vehicles, engineered specifically for Nissan transmissions to meet NS-3 specifications.
TRIAX CVT ATF OEM Grade
Surpasses OEM fluid performance, offering reliable, longer-lasting performance for CVTs with chain or belt transmissions. It is fully compatible with CVTs from many OEMs and is designed to reduce noise and shudder while providing consistent oil film for quiet, high-speed shifting.
Buying Guide: Key Purchase Considerations for CVT Fluids
When choosing CVT fluid, buyers should assess several factors to ensure compatibility, performance, and longevity. This guide presents a balanced view across different perspectives.
- Vehicle-specific specifications: Always verify the exact CVT fluid specification required by your vehicle (e.g., NS-2, NS-3, SB2). Using the wrong specification can cause clutch slippage, shifting issues, or damage over time.
- Compatibility versus universality: OEM-specific fluids guarantee compatibility with a given model, but universal CVT fluids aim to cover multiple brands. If your vehicle is brand-specific or you want maximum assurance, prefer OEM fluids.
- Synthetic content: Synthetic CVT fluids generally provide broader temperature performance, better oxidation resistance, and longer service life. Mineral blends may be adequate for some older transmissions or light-duty usage.
- Driving conditions: Consider climate, stop-and-go city driving, towing, or high-load driving. High-temperature stability and anti-shudder features become more important in extreme conditions.
- Maintenance interval and capacity: Follow manufacturer recommendations for intervals and fluid capacity. Some CVTs require complete drain-and-fill, others permit top-offs only during service.
- Aging and deposits: Some brands emphasize deposit control and anti-wear additives to protect belts and pulleys under high torque, which can be crucial for aging CVTs.
- Cost and availability: While OEM fluids may be pricier, they provide guaranteed compatibility. Universal fluids offer convenience and broad coverage but verify coverage for your specific model.
- Dealer vs aftermarket: Dealers may require OEM fluids for maintenance records. Aftermarket fluids can be suitable as long as they meet the exact spec.
In summary, select a CVT fluid that matches your car’s specification, aligns with your driving conditions, and fits your maintenance plan. The products highlighted here provide a range of OEM-grade and universal options, illustrating the trade-offs between manufacturer-specific compatibility and broad applicability.
