What is the minimum and maximum speed for 2nd gear?

[MacSkylar]

2nd gear speed should not be lower than 20 or higher than 30. Below is relevant information about gears: 1. Concept: Gears are adjustment devices that regulate a car's speed and traction (torque). The lower the gear, the slower the speed, but the greater the car's traction (torque). The higher the gear, the faster the speed, but the smaller the car's traction (torque). Gears are generally divided into two categories: forward gears and reverse gears. Engaging forward gears makes the car move forward, while engaging reverse gear makes the car move backward. 2. Standard car gears: Typically, standard cars have five forward gears and one reverse gear. First gear is the starting gear, where the speed is the slowest (0-10 km/h), but the torque is the greatest.

I've been driving for twenty years and always use second gear with extra caution because driving at excessively low speeds can cause lugging damage to the engine. Generally, it's advised not to go below 10 to 15 kilometers per hour—for instance, when you notice the car shaking or the engine sounding labored, it's time to downshift. Conversely, exceeding 40 to 50 kilometers per hour in second gear can push the engine RPM into the danger zone, risking overheating and part damage. The exact thresholds vary by model; my old sedan’s second gear tops out at 45 km/h, while my newer SUV handles slightly higher speeds. The key is to listen closely to the engine—if it sounds strained, adjust the gear promptly to protect the car and improve fuel efficiency. In city traffic, I often rely on second gear for speed control, but prolonged operation at very low or high speeds drastically increases fuel consumption. Regularly checking transmission fluid is also crucial to prevent accelerated wear. These simple practices ensure safer and more economical driving.

I often encounter second gear issues when repairing cars, and owners frequently ask about speed limits. Going too slow, like below 5 km/h, can cause the engine to choke and vibrate, damaging the connecting rods over time. It's recommended to maintain speeds above 15 km/h. On the other hand, going too fast over 50 km/h leads to excessively high RPMs, which not only consumes more fuel but can also burn out the valves. Different vehicles have varying ranges, with smaller cars having a narrower range and larger SUVs a slightly wider one. The key is to watch the tachometer and shift before hitting the red zone. In practice, don't rigidly memorize numbers; in city driving, second gear is suitable for speeds between 20 to 40 km/h, as long as no abnormal noises are heard. Avoid prolonged lugging or high RPMs to extend engine life and reduce maintenance frequency. Remember, regular transmission maintenance is a fundamental aspect of daily driving.

When I first learned to drive, my instructor said not to keep the second gear too low or too high to avoid problems. If the speed is too low (below 10 km/h), the engine will sound muffled and may get damaged. It's best to start at around 15 km/h. If the speed is too high (exceeding 50 km/h), the RPM will surge sharply with a harsh noise, which can easily wear out the transmission. Every car is different; my compact car performs best between 20 to 45 km/h in second gear. The key for beginners is to practice more and get a feel for it: as long as the car body isn’t shaking, it’s safe. Don’t force second gear when the higher gears lack power. In city stop-and-go traffic, using second gear for control can save fuel, while low-speed operation wastes fuel. At higher speeds, wind noise increases, requiring more focus. Safety first—remember to shift gears promptly and develop good habits to reduce accidents.
