What are the differences between manual transmissions and automatic transmissions?

[DeEvangeline]

The differences between manual transmissions and automatic transmissions are: 1. Different principles: A manual transmission uses a gear lever to change the meshing position of gears inside the transmission, altering the gear ratio to achieve shifting; An automatic transmission shifts gears automatically based on the vehicle's speed and engine RPM. 2. Different characteristics: Manual transmissions are known for their stable performance, high transmission efficiency, and excellent fuel utilization; Automatic transmissions offer convenient operation and flexible gear ratios. The transmission is a mechanism used to change the speed and torque from the engine, capable of fixing or changing the gear ratio between the output shaft and input shaft in steps, also known as the gearbox.
