What are the explanations for manual transmission gears?

Manual transmission, also known as MT, refers to a transmission system where the driver manually shifts gears by moving the gear lever to change the gear engagement inside the transmission, thereby altering the gear ratio for speed adjustment. Below are the explanations for manual transmission gears: 1. 1st gear: Used for normal starting or climbing very steep slopes. The speed typically ranges around 10 km/h when using this gear; 2. 2nd gear: Used as a transition gear for acceleration after starting, or for low-speed driving or climbing steep slopes. The speed usually ranges around 20 km/h; 3. 3rd gear: Generally used when the speed is between 20 km/h and 40 km/h, commonly used for city driving; 4. 4th gear: Can be used when the speed is between 40 km/h and 60 km/h; 5. 5th gear: Used when the speed exceeds 60 km/h, typically for high-speed driving; 6. N gear: N stands for neutral, used when the vehicle is idling, such as when waiting at a traffic light. Shift to N gear and engage the handbrake; 7. R gear: R stands for reverse, used for reversing after the vehicle has come to a complete stop.
When I first learned to drive, the manual transmission gears had me all flustered. R is the reverse gear, which must only be used after the car has come to a complete stop, otherwise it'll make a grinding sound and damage the transmission; N is neutral, where the car neither moves forward nor backward, very handy when parked or waiting at red lights. Start off in 1st gear, gently press the accelerator to move slowly; shift to 2nd gear when speed reaches 15-20 km/h; then around 35 km/h upshift to 3rd, and at 60 km/h shift to 4th or 5th; on highways, 5th or 6th gear is most fuel-efficient. The ideal RPM range for shifting is between 2000 to 3000 - below 1000 RPM the car will shudder, while above 4000 RPM burns more fuel. When climbing hills, downshift to lower gears like 2nd; use 3rd gear for engine braking when going downhill for safety. Make it a habit to leave the car in 1st or R gear when parked to prevent rolling, don't rely solely on the handbrake. Manual transmissions require practicing hand-foot coordination - release the accelerator when depressing the clutch, and push the gear lever fully into position or it won't engage. Throughout the process, watch the tachometer and listen to the engine sound - you'll gradually get the hang of it. The feeling of complete control over the car is fantastic, but it takes practice to master.
After driving manual transmission for over a decade, I've concluded that gear selection is the key to fuel efficiency and safety. Start in 1st gear, then shift to 3rd or 4th gear early as speed increases, maintaining engine RPM between 1800-2500 for optimal fuel economy. In stop-and-go traffic with frequent 1st-2nd gear shifts, lightly depress the clutch to reduce jerking and avoid stalling from abrupt acceleration that could cause rear-end collisions. Downshift to 2nd gear uphill for increased torque, and use 3rd gear downhill for engine braking to preserve brake pads. On highways, use 5th gear or higher for fuel savings. When parking, engage a gear (I prefer 1st or Reverse) to prevent rolling. Wrong gear selection carries risks: accidentally shifting to lower gear at high speed may cause loss of control, and always check mirrors before reversing. My golden rule: anticipate road conditions for smooth gear changes - like downshifting before descents, or using lower gears for better traction in rain. Mastering gear coordination extends vehicle lifespan and reduces maintenance costs.
The design of manual transmission gear ratios is quite interesting. Each gear has a different ratio: 1st gear has a large ratio, suitable for starting from standstill up to 20km/h; shifting to 2nd gear takes you up to 40km/h; higher gears like 4th cover 50-70km/h, while 5th and 6th gears are ideal for fuel-efficient and smooth highway cruising. The R (Reverse) gear provides backward motion for reversing, and N (Neutral) disengages power transmission for idling. During operation, pressing the clutch pedal disconnects the engine, the shift lever moves the selector fork to engage different gears, and releasing the clutch reconnects power. This process prevents lugging (straining the engine at low RPM) or redlining (over-revving and damaging the engine). In daily driving, match vehicle speed and RPM when selecting gears: urban driving often uses 2nd gear for control, while 5th gear is perfect for highway cruising. Manual control offers more direct feedback and reduces drivetrain wear.
