What is the difference between 6AT and CVT transmissions?

[VanFinley]

AT transmissions have excellent load-bearing capacity but are not as smooth as CVTs and are more costly; CVTs offer superior smoothness and lower costs but have limited load-bearing capacity. The specific details are as follows: 1. 6AT Transmission: The torque-bearing capacity of a 6AT transmission is very strong, which is why off-road vehicles use AT transmissions—even heavy loads pose no problem for AT transmissions. The previous notion that AT transmissions are not fuel-efficient can almost be dismissed, as modern AT transmissions are highly advanced. However, the smoothness of AT transmissions still cannot compare to CVTs, and they are more expensive. 2. CVT Transmission: CVT transmissions provide excellent fuel economy, unmatched driving smoothness, effectively reduce emissions, and are cost-effective. However, when subjected to excessive loads, they are prone to slipping, and extreme loads may even cause the steel belt to break. For typical family cars, the load is usually not enough to reach the breaking point.
