What are the disadvantages of DCT transmission?

[AliceFitz]

DCT transmission has disadvantages such as high cost, slightly weaker reliability and durability. The specific details are as follows: High cost: Due to the complex structure of the dual-clutch system in cars and the high manufacturing process requirements, the cost is relatively high. Therefore, vehicles equipped with dual-clutch transmissions are mostly mid-to-high-end models. In terms of torque, dual-clutch transmissions can absolutely meet the requirements of general vehicles. Slightly weaker reliability and durability: The reliability and durability are not as good as AT transmissions and CVT transmissions. Additionally, the smoothness of gear shifting is not as good as CVT and AT transmissions. Advantages of DCT: Fast gear shifting, fuel-efficient, and relatively comfortable. Because the gear shifting time of a car's dual-clutch is very short, even faster than manual transmissions, taking less than 0.2 seconds, the sense of jerk is relatively small, and the comfort is higher. Moreover, operating at the optimal working state can significantly save fuel.
