How does AMT work?

AMT (Automated Manual Transmission) is a transmission system that combines the mechanical structure of a manual gearbox with automatic shift control functions. When the vehicle is in motion, the ECU monitors parameters such as engine speed, vehicle speed, and throttle opening in real time, automatically controls the engagement and disengagement of the clutch, and drives the shift mechanism to complete gear changes without the need for driver intervention. Compared to traditional automatic transmissions (AT), AMT retains the high transmission efficiency (improving fuel economy by approximately 5-10%) and low-cost advantages of manual transmissions, but its shift smoothness is slightly inferior, especially with possible jerking at low speeds. Currently, local market models such as the Perodua Axia EZ adopt this technology; their maintenance costs are about 15-20% lower than those of AT vehicles, making them suitable for consumers who prioritize economy. AMT vehicles may require coordination with the handbrake to prevent rolling when starting on slopes, which is a limitation determined by their mechanical structural characteristics.
