What does the 1 and 2 gear mean in the Tiida?

In an automatic transmission car, the 1 and 2 gears are low-speed limiting gears that ensure maximum power output. The 2 gear in an automatic car, also known as the low-speed forward gear, is a limiting gear. When the car's transmission is in this gear, it is used for starting on slippery surfaces or as a limiting gear when moving slowly forward. When climbing a steep slope or starting on a relatively steep incline: You can use this gear to start moving forward. By shifting into this gear, you can limit the car's gear shifting to only low gears (equivalent to the first and second gears in a manual transmission car), ensuring the car obtains maximum forward power. The 1 gear in an automatic transmission is also a low forward gear. When going downhill or descending a long slope: By shifting into this gear, you can limit the car's gear shifting to only the lowest gear (equivalent to the first gear in a manual transmission car). This allows the car to use the engine's power for braking when going downhill, preventing the driver from having to press the brakes for extended periods, which could overheat the brake pads and cause danger. In this mode, the transmission can only operate within the 1 gear and cannot shift to other gears. It is most effective in situations of severe traffic congestion or on steep slopes. When ascending or descending a slope, you can fully utilize the torque of the car's engine.
When my Tiida manual transmission starts, both 1st and 2nd gears are crucial low-speed gears. 1st gear is suitable for starting from a complete stop, such as after a red light or when going uphill. It provides high torque to allow gradual acceleration, but the speed is only around 10 km/h. 2nd gear is typically used when the speed reaches 15 to 20 km/h, serving as a transitional gear to smoothly increase speed from low to medium. These gears are designed to protect the engine and avoid damaging parts at high RPMs. The Tiida's transmission is relatively durable, but frequent launches in 1st gear will accelerate clutch wear. I recommend that beginners practice smooth gear shifting to ensure the engine runs smoothly, while also remembering to check if the transmission oil is fresh. Remember, proper gear usage can improve fuel efficiency and reduce the occurrence of sudden braking.
Friends familiar with car performance know that the 1st and 2nd gears of the Tiida belong to the basic gears of a manual transmission. The 1st gear has a large gear ratio, making it suitable for climbing steep slopes or towing heavy loads, allowing the wheels to achieve maximum traction. The 2nd gear is designed as a transitional phase, used for low-speed acceleration, such as accelerating from 20 km/h to 40 km/h, providing a smoother driving experience. Long-term neglect of these gears may lead to excessive engine load and even shorten the engine's lifespan. Some modification enthusiasts might lower the gear ratio to improve starting speed, but the factory settings are already sufficient. Pay attention to regular transmission maintenance to avoid gear shifting hesitation. Maintaining a steady speed while driving is also beneficial for the environment.
