What gear should be used for automatic transmission when climbing a steep slope?

[LuciaAnn]

For automatic transmission when climbing a steep slope, use the low gear. It is particularly useful in heavy traffic conditions or on steep inclines. When ascending or descending a slope, the low gear allows full utilization of the engine's torque, making it easier for the vehicle to climb steep slopes. The low gear provides greater torque, commonly referred to as more power. By shifting into the low gear, you limit the transmission to stay in the lowest gear, enabling the engine to assist in braking when going downhill. This prevents the driver from having to press the brakes continuously, which could overheat the brake pads and pose a danger. In this mode, the transmission remains in first gear and does not shift to other gears.
