What do the letters on a manual transmission represent?

[TimothyMarie]

The letters on a manual transmission represent: 1. N stands for neutral gear; 2. R stands for reverse gear. A manual transmission car uses a manual gear-shifting mechanical transmission to adjust vehicle speed, meaning that manually moving the gear lever can change the gear meshing positions inside the transmission, altering the gear ratio to achieve speed variation. The clutch must be depressed to move the gear lever. The steps for starting a manual transmission car are: 1. Fully depress the clutch; 2. Shift into first gear; 3. Turn on the left turn signal; 4. Sound the horn as a reminder; 5. Release the handbrake; 6. Gently lift the clutch with the left foot; 7. As the vehicle begins to move, keep the clutch steady with the left foot, avoiding any pressing down or lifting movements to prevent stalling; 8. After holding steady for 3 seconds, slowly release the clutch while gently pressing the accelerator with the ball of the right foot. Slowly release the accelerator, fully depress the clutch to shift into second gear, then repeat this process to shift into third gear, completing a smooth vehicle start.
