When switching from a manual to an automatic transmission, you do not need to retake the written test (Subject 1) because the C1 driver's license covers the vehicle types included in the C2 license. Once you have passed the Subject 1 test, you can apply to change your license to a C2 type without retaking the written test. Simply request the change from your driving school, which will then handle the modification of the registered license type with the vehicle management office. Differences between automatic and manual transmission tests: Different licenses: A manual transmission license is a C1 driver's license, while an automatic transmission license is a C2 driver's license. A C1 license allows you to drive vehicle types covered by C2, but a C2 license does not permit driving vehicle types covered by C1. Different vehicle types: A C1 license permits driving small and micro passenger vehicles, light and micro cargo vehicles, and specialized light, small, or micro operation vehicles, as well as small passenger vehicles with fewer than 9 seats. A C2 license allows driving small and micro automatic transmission passenger vehicles, light and micro automatic transmission cargo vehicles, and small automatic transmission passenger vehicles with fewer than 9 seats. Different driving difficulty: Learning to drive a manual transmission is more challenging than an automatic transmission. Since automatic transmission vehicles do not have a clutch, they use a hydraulic transmission system that automatically shifts gears within a certain range under the control of the brake and accelerator, eliminating the need for clutch operation. As a result, driving an automatic transmission vehicle is simpler, more convenient, and smoother than driving a manual transmission vehicle.
