What are the differences between manual and automatic transmission cars?
1 Answers
Differences between manual and automatic transmission cars: 1. Different transmissions: Manual transmission cars use manual gearboxes; Automatic transmission cars use automatic gearboxes. 2. Different operations: Manual transmission cars rely on human effort to depress the clutch to complete gear shifting operations; Automatic transmission cars rely on the hydraulic transmission principle of torque converters to automatically complete gear shifting. 3. Different working principles: Manual transmission cars change gear ratios by moving the gear lever to alter the meshing position of gears inside the transmission, achieving speed variation; Automatic transmission cars use planetary gear mechanisms for speed variation, which can automatically shift gears based on the degree of throttle pedal and changes in vehicle speed. 4. Different gear markings: The gear markings for manual transmission cars are 1, 2, 3, 4, 5, 6, R; The gear markings for automatic transmission cars are P, R, N, D.
