Can a CVT transmission coast in neutral?

[OElliot]

CVT transmissions cannot coast in neutral, and coasting in neutral is also a driving behavior explicitly prohibited by Chinese law, which is very dangerous. Hazards of coasting in neutral: Most fuel injection engine control systems have a deceleration fuel reduction or fuel cut-off function. For these fuel injection engines, coasting in neutral is no longer necessary for fuel-saving operations. In fact, coasting in neutral can turn "fuel-saving" into "fuel-wasting" and is highly harmful to the vehicle. Fault issues caused by coasting in neutral: When driving in gear, the transmission oil can be cooled by circulating water through the oil pump. In neutral, the transmission oil cannot be circulated and cooled by the oil pump. Prolonged coasting in neutral can cause the oil temperature to rise, burning the clutch plates immersed in it and leading to transmission failure.

I think it's best not to coast in neutral with a CVT transmission, based on what I've learned from self-studying cars. CVTs rely on a belt connecting pulleys to transmit power. When coasting in neutral, the engine idles at low speed, resulting in insufficient pressure from the transmission oil pump and poor lubrication. This can cause increased wear or even slippage between the pulleys and belt. Over time, components may overheat and deform, potentially leading to transmission failure. Modern CVT-equipped vehicles have protective mechanisms, but it's not worth the risk when coasting. It's safer to coast in Drive (D), as the engine can assist with braking, reducing brake load. This also saves fuel since the vehicle automatically cuts off fuel supply. Regular transmission fluid checks can prevent issues, but if you make a habit of coasting in neutral, repair costs can be quite high.

I always pay attention to safety when driving myself, and coasting in neutral with a CVT car is too risky. When coasting in neutral, the engine disconnects, losing engine braking, and relying solely on the brakes. On downhill slopes, the brakes may overheat and fail, increasing the chance of accidents. Especially on rainy days when the road is slippery, the probability of losing control of the vehicle is even higher. The CVT transmission has a delicate structure, and its lubrication depends on oil pressure. The oil pump is less efficient in neutral, causing the belt to wear out faster. It is recommended to use neutral only when parking and to keep the car in drive while driving to ensure safe operation. Once, a friend tried coasting on the highway, and the transmission made strange noises, requiring repairs—costly and dangerous.
