Transmission, also known as a gearbox, is an automotive component used to alter the speed and torque from the engine, and it can fix or change the gear ratio between the output and input shafts. The K3 uses the following three types of transmissions: 1. 6-speed manual transmission: simple in structure, reliable in performance, low in manufacturing and maintenance costs, and high in transmission efficiency. 2. 6-speed automatic manual transmission: combines the advantages of automatic and manual transmissions, minimizing power loss in the transmission system. 3. 7-speed dual-clutch transmission: ensures smooth vehicle starts, reduces impact loads on transmission gears during shifting, and prevents overload in the drivetrain.









Last year, I bought a 2020 K3 equipped with a 6-speed automatic transmission. It drives really smoothly, especially in city traffic where gear shifts are seamless without any noticeable jerking. On the highway, acceleration is steady, and fuel consumption is reasonable, averaging around 6 to 7 liters per 100 kilometers. As an owner, I find the automatic transmission particularly suitable for beginners and daily commuting—it's simple to operate and not tiring. For transmission maintenance, I change the transmission fluid every two years to prevent any unusual noises. If you're buying a used K3, be sure to check for signs of aging or oil leaks in the transmission, as wear and tear can occur over time. Overall, the transmission is quite reliable; I haven't had any major issues so far, except for occasional slight delays during cold starts.

As a car enthusiast, the K3 uses different transmissions depending on the model. Older models mostly had 5-speed manual or 4-speed automatic transmissions, while the current mainstream options are 6-speed automatic transmissions and CVT. The CVT is more fuel-efficient and offers smoother driving, but its power response isn't as quick as the automatic transmission. I've researched the K3's transmission design, such as the intelligent lock-up clutch in the automatic version, which improves fuel efficiency. For maintenance, avoid aggressive driving, sudden braking, and rapid acceleration to extend its lifespan. Compared to the Honda Civic's transmission, the K3's response speed is similar but more durable. Early versions had recall issues mainly related to gear shifting hesitation, but newer models have seen significant improvements. When choosing a car, it's recommended to test drive and feel how well the transmission matches the engine's smoothness, as it directly affects driving pleasure.

I drove my colleague's K3 in the manual transmission version, which comes with a standard 5-speed or 6-speed gearbox. The operation is straightforward and simple, with a light clutch suitable for urban driving conditions. It has quick acceleration response and is slightly more fuel-efficient than automatic transmissions, but it can be tiring for the hands on long drives. This gearbox is easy to maintain, requiring only regular oil checks and changes, and it rarely has issues. Occasionally, there might be slight noise in low gears, but overall it's reliable. If you often drive on highways, choosing the manual transmission version of the K3 is a good option.

Our family's 2018 K3 is equipped with a standard 6-speed automatic transmission. The driving experience is comfortable with smooth gear shifts, making it friendly for both elderly and children without any jerking sensation. During daily school runs in traffic jams, the transmission responds promptly, reducing fatigue. Fuel consumption remains acceptable at under 8 liters. In terms of reliability, it has been trouble-free for five years with only regular maintenance required. Compared to the Hyundai Elantra, the K3's transmission operates more quietly with less noise. For maintenance, it's recommended to check the fluids every 40,000 kilometers to prevent overheating damage. If opting for the K3 automatic version, it proves suitable for safe and worry-free family daily use.

I remember the transmission evolution of the K3 is quite noticeable, upgrading from the old 4-speed automatic to the current 6-speed automatic or the new IVT. The IVT is similar to a CVT, offering smoother driving and better fuel efficiency, though acceleration is slightly slower. For manual transmissions, most are 6-speed versions, which provide direct operation and lower maintenance costs. I've driven a manual K3, and its clutch is light and responsive, making it convenient for city driving, though long-distance comfort is lacking. The overall transmission design is durable, capable of lasting ten years without major issues, but regular replacement of parts like filters is necessary. Compared to the Toyota Corolla's transmission, the performance is similar, but the K3 is more affordable. When choosing a K3, just select the transmission type based on your driving habits—automatic is more suitable for relaxed driving.
