Let’s learn more about cars, and today we’ll talk about the differences between transmissions. First, a quick question: which do you think is better—CVT, dual-clutch, AT, or manual transmission?
First up is the king of automatic transmissions, the AT transmission, often called the king of durability. It works by using a torque converter to transmit power. The engine and transmission don’t have a rigid gear mesh; instead, there’s a layer of fluid acting as a buffer, like a soft connection, avoiding direct impact. The advantage is its exceptional durability; it can withstand anything, from mountainous terrain to river crossings. Therefore, most luxury cars use AT transmissions for stability, including tanks, because they are incredibly durable. The disadvantage is its complex internal structure; if it does break down, the repair costs are high. Cars using AT transmissions are also more expensive and have higher fuel consumption than other automatic transmission cars.
Having learned about the most durable AT, let’s now look at the fastest shifting dual-clutch transmission. Its principle is quite interesting; it’s essentially two manual transmissions combined. One controls first, third, fifth, and seventh gears, while the other controls second, fourth, sixth, and reverse gears. The computer pre-selects the next gear, resulting in extremely fast shifting. Because it’s a direct gear-to-gear connection, power output is almost uninterrupted, making it not only fast-accelerating but also fuel-efficient, with no drawbacks on highways or elevated roads. However, in stop-and-go traffic, the dry dual-clutch transmission is prone to jerking and vibration, and may overheat over time. Its comfort and durability are still inferior to an automatic transmission.
Next is the CVT transmission, which emphasizes comfort and smoothness to the point of being unbelievable. It doesn’t have traditional fixed gears; instead, it uses a steel belt and two conical pulleys to change diame
