Automatic transmission gear 1 and gear 2 are used as follows: 1. Gear 1 in an automatic transmission is the low-speed forward gear. When going downhill or descending a long slope, shifting into gear 1 restricts the car to the lowest gear, allowing the engine to provide braking power. This prevents the danger of brake overheating caused by prolonged braking. 2. Gear 2 in an automatic transmission, 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 for slow forward movement. When climbing a steep slope or starting on a significantly inclined surface, starting in gear 2 ensures the car gains maximum forward momentum.

When I first drove an automatic transmission car, I didn't understand these gears well either. Later, I learned their clever applications while driving on mountain roads. First gear (1) is specifically for steep uphill climbs, like those with significant gradients on winding mountain roads. When you engage first gear, the car won't shift frequently, maintaining low gear and high torque, making the climb more fuel-efficient and smoother. Second gear (2) is used when going downhill, such as on long downhill slopes. It prevents the transmission from shifting to higher gears, utilizing engine braking to control speed, which prevents the braking system from overheating and wearing out. I remember once descending a mountain in rain and snow; using second gear stabilized my speed without skidding, making it much safer. However, remember not to use these gears arbitrarily on straight, flat roads, as it could damage the engine or waste fuel. With more practice and consideration of road conditions, your driving will be more assured and better for your vehicle.

As a new driver, I initially didn't understand the purpose of gears 1 and 2 on an automatic transmission. Later, I consulted an experienced driver who explained that gear 1 is used when climbing steep slopes, such as the exit of an underground parking lot at a shopping mall. Shifting to this gear makes the car feel like it has extra power, easily ascending the slope. Gear 2 is engaged when going downhill or on slippery surfaces, such as a rainy day on a residential slope, as it restricts upshifting to prevent skidding and maintain steady speed. I once tried using gear 2 on a gentle downhill slope and felt much more secure with reduced brake pressure. The key is to operate according to actual conditions and avoid randomly selecting these gears at high speeds to prevent excessive RPMs that could damage the engine. I recommend checking your car's manual, as it usually provides detailed explanations of applicable scenarios. With gradual experience, you'll find these lower gears incredibly helpful, enhancing both driving enjoyment and safety.

From my years of driving experience, I've learned that the 1st gear in automatic transmissions is best for extreme uphill climbs to provide maximum traction, while the 2nd gear is ideal for downhill speed control to prevent overspeeding. Make sure to use them in the right situations, such as starting or stopping on steep slopes or driving on icy or snowy roads, to maximize their effectiveness. They're simple and easy to use but require caution to avoid damaging the vehicle.
