I respectfully have to disagree with the first answer. The transmission is sealed and therefore take very little service. Depending on the vehicle, it's true that they recommend service every 30,000 to 60,000 miles, but it's only a fluid drain and refill. No substantial work is done and they are extremely reliable. Nissan is one of the best selling car brands in America, and virtually every car they make contains a CVT transmission.
