Idemitsu CVT Transmission Fluid NS-3 – 6 x 1 Qt Bottles, Nissan-compatible, Anti-Shudder & Seal Protection

Idemitsu CVT Type N3 (NS-3) is a factory-compatible CVT transmission fluid sold in a six-pack of 1-quart bottles, engineered specifically for Nissan continuously variable transmissions that specify NS-3.

If you own a Nissan vehicle that requires NS-3 fluid, this Idemitsu formulation delivers the friction properties, seal care, and oxidation resistance those transmissions need. Packaged as six one-quart bottles, it suits DIY maintenance and small shop service intervals. The fluid is designed to control shudder, stay clean under heat, and preserve seals to reduce leaks, while meeting international quality certifications for consistent performance.

How does this fluid prevent CVT shudder and maintain smooth gearless operation?

The formula provides calibrated friction behavior so the metal belt and pulley contact in CVTs engage smoothly without abrupt slipping or judder. It balances grip and slip characteristics to help preserve the original drive feel while minimizing vibration under variable loads.

• Engineered friction modifiers tuned for Nissan NS-3 specifications
• Reduces micro-slip that causes shudder during acceleration
• Maintains stable viscosity across operating temperatures

What protections does it offer against wear, deposits, and overheating?

This fluid resists oxidation and thermal breakdown to slow varnish and sludge formation, keeping internal parts and valves cleaner over time. It also contains additives that protect metal surfaces from wear and preserve hydraulic clarity for reliable control circuitry inside the CVT.

• Antioxidant chemistry for extended fluid life at high temperatures
• Detergent and dispersant agents to limit deposits and varnish
• Wear inhibitors to protect bearings and pulleys

Is it compatible with seals, and can it help prevent leaks?

Yes — the fluid includes seal-conditioning components to keep elastomers supple and dimensionally stable, reducing the risk of shrinkage or hardening that can cause leaks. Proper seal compatibility helps maintain a tight system across a broad temperature range and over long drain intervals.

• Formulated for common CVT elastomer materials used in Nissan transmissions
• Helps prevent seal cracking, shrinking, or hardening
• Supports leak prevention through long-term conditioning

What certifications and service uses should I expect from this product?

Idemitsu CVT Type N3 meets industry and manufacturer-aligned quality standards, including ISO and IATF certifications, ensuring consistent manufacturing and performance. It is intended specifically for Nissan CVTs specifying NS-3 and is not a universal transmission oil for other transmission types.

• Manufactured to ISO and IATF-certified quality processes
• Designed specifically for applications requiring NS-3 fluid specifications
• Sold as six 1-quart bottles to support multi-bottle service needs

Who is this for? This six-pack of 1-quart Idemitsu CVT Type N3 fluid is aimed at Nissan owners, independent mechanics, and service shops that perform CVT maintenance on vehicles calling for NS-3. If you need factory-style friction control, seal compatibility, and resistance to thermal breakdown for your Nissan CVT, this product provides the matched specification and quantity suitable for drains, top-ups, or small fleet servicing. It is not intended for conventional automatic or manual transmissions that require different fluid formulations.
