Downshifting in an automatic transmission is particularly beneficial when going downhill. When a vehicle descends a hill, gravity can cause it to accelerate faster than desired. By downshifting, the driver allows the engine to take on some of the load, using engine braking to help slow the vehicle down. This technique reduces reliance on the brakes, which can overheat and wear out faster when continuously applied during long downhill stretches.

While there may be instances where downshifting could be considered in other scenarios, such as making sharp turns or in certain driving conditions, doing so specifically while going downhill is about maintaining control and safety. This is crucial in preventing the vehicle from gaining excessive speed and potentially losing traction or control.
