How often should the Nissan CVT transmission fluid be changed?
2 Answers
Nissan CVT transmission fluid should be changed approximately every 40,000 to 60,000 kilometers. It is essential to use the manufacturer's dedicated CVT transmission fluid because: different automatic transmissions have varying internal structures, friction components, and sealing elements. The manufacturer's fluid is specially formulated based on the transmission's structure and materials. Other situations requiring transmission fluid replacement include: sluggish acceleration, gear shift hesitation, or rough shifting. Transmission fluid is an oil product that maintains the cleanliness of the gear system, providing lubrication to prolong the lifespan of the transmission components. It offers low-temperature resistance, ensuring effective lubrication even in cold conditions, and reduces fluid loss under severe operating conditions.
I've been driving Nissan cars for almost ten years and have used several different CVT models, such as the Sylphy and X-Trail. Based on my experience and the recommendations in Nissan's official manual, the CVT transmission fluid generally needs to be replaced every 30,000 to 60,000 kilometers, or every two to four years, depending on your driving frequency and road conditions. I do a lot of city driving, so I change the fluid every two years because congested roads can cause the fluid temperature to rise, making it dirty and prone to aging. CVT transmissions have high requirements for the fluid—if it gets too old, you might experience gear slippage, strange noises, or even transmission damage, which can be expensive to repair. I recommend paying attention to any rough shifting sensations while driving and getting a professional inspection when it's time, without delaying too long. In hot weather or dusty environments, it's even more important to shorten the fluid change interval to protect the transmission's core components and extend its lifespan.
