Continuously Variable Transmissions (CVT) are designed to provide a smooth and efficient driving experience by using a variable pulley system which allows for an infinite range of effective gear ratios. One important characteristic of CVT transmissions is that they require a special type of transmission fluid. This fluid is often specifically formulated to meet the unique requirements of CVTs, including properties that allow for smooth operation and the ability to handle the specific stress and heat generated in these systems.

Using the correct type of transmission fluid is vital for the performance and longevity of a CVT. Standard transmission fluids used in traditional automatic and manual transmissions may not provide adequate lubrication or thermal protection for a CVT. This tailored fluid helps provide optimal performance, enhancing the efficiency advantages that a CVT can offer over traditional gear-based transmissions.

While other options may touch upon aspects related to maintenance or fluid types, they do not accurately define a characteristic inherent to the operation of CVTs like the necessity for a special transmission fluid does. Instead, they may pertain to different transmission systems or maintenance practices rather than the unique requirements of CVTs specifically.
