Does Chevrolet's gearbox work well? Is it easy to break down?

At present, Chevrolet's 9-speed automatic manual transmission is an advanced 9AT gearbox in the world, including more than 60 patented technologies. It has a wider speed ratio range and finer gear allocation, and can cut into the ninth gear within 95km/h, which can bring drivers a smoother power experience and more efficient fuel economy. Absolutely very easy to use. As for the failure rate, the manual transmission is generally not easy to break down, and the failure rate and complaint rate of Chevrolet can be found on the car quality network, which is very low.
