Honda Continuously Variable Transmission (CVT) Fluid is used specifically in vehicles with first generation CVTs. Instead of using fixed gear ratios like in a conventional transmission, the CVT varies ratios continuously based on engine speed, vehicle speed, and other driving conditions. Made with the newest technology based oils and additives for: Increased oxidation resistance, fewer deposits and longer drain intervals. Better fluidity at cold temperatures for easier starting. Advanced wear protection to reduce wear and increase service life. CVT fluid is not compatible with HCF-2 or any other fluid and should not be used in second generation
