A Nissan Continuously Variable Transmission (CVT) typically requires 4 quarts of fluid for a standard drain and refill service. It is critically important to use only Nissan-specific CVT fluid for this procedure.
Nissan CVTs are engineered to operate with very specific fluid properties, and using anything other than the manufacturer-recommended fluid can lead to serious transmission damage and costly repairs.
Understanding CVT Fluid Capacity
The 4-quart figure refers to the amount of fluid typically drained and replaced during a routine fluid change. This is often called a "drain and fill" and does not represent the transmission's total fluid capacity. A full transmission "flush" or complete fluid exchange, which requires specialized equipment, would involve a larger volume of fluid, often closer to 8-10 quarts, depending on the model.
Important Considerations for Nissan CVT Fluid:
- Nissan Genuine Fluid ONLY: Nissan CVTs are designed to work exclusively with Nissan NS-2 or NS-3 CVT fluid, depending on your vehicle's model year and specifications. Using generic or non-Nissan approved fluids can cause shuddering, erratic shifting, and premature transmission failure. These fluids have unique friction modifiers and viscosity characteristics essential for CVT belt and pulley operation.
- Drain and Fill vs. Flush: A drain and fill replaces only a portion of the old fluid. While this is often sufficient for regular maintenance, some experts recommend multiple drain and fills over time, or a professional flush, to replace a larger percentage of the old fluid. Always consult your owner's manual for recommended service intervals.
- Checking Fluid Level: After a fluid change, ensuring the fluid level is correct is crucial. Nissan CVTs often have specific procedures for checking the fluid level, sometimes requiring the transmission to be at a particular temperature. An incorrect fluid level (too high or too low) can lead to operational issues.
Typical Nissan CVT Fluid Capacities (Drain & Fill)
While 4 quarts is a common amount for a drain and refill, capacities can vary slightly by model and year. Always refer to your vehicle's owner's manual for the most accurate information.
| Nissan Model (Typical) | Fluid Type Recommended | Approximate Drain & Fill Capacity |
|---|---|---|
| Sentra, Versa, Altima | Nissan NS-2 or NS-3 | 4 Quarts |
| Rogue, Murano | Nissan NS-2 or NS-3 | 4-5 Quarts |
| Maxima | Nissan NS-2 or NS-3 | 4 Quarts |
Note: These are approximations for a standard drain and fill. Total system capacity is higher.
Why Specific Fluid is Crucial for CVTs
CVT transmissions operate differently from traditional automatic transmissions. Instead of gears, they use a system of belts and pulleys to continuously vary gear ratios. The fluid in a CVT serves multiple critical functions:
- Lubrication: Reduces friction between moving parts.
- Cooling: Dissipates heat generated during operation.
- Power Transfer: Transmits power to the belt and pulleys through hydraulic pressure and precise friction characteristics.
- Cleaning: Carries away debris and contaminants.
Nissan's NS-2 and NS-3 fluids are specifically formulated to provide the precise friction necessary for the belt to grip the pulleys without slipping, while also lubricating other components. Using incorrect fluid can disrupt this delicate balance, leading to premature wear, performance issues, and ultimately, transmission failure.

It is always recommended to consult your vehicle's owner's manual or a certified Nissan technician for precise fluid requirements and service procedures for your specific model.
