Do You Need to Press the Brake When Shifting from D to S in an Automatic Transmission?
2 Answers
Shifting from D to S in an automatic transmission does not require pressing the brake. Below are the relevant details: 1. No need to press the brake while driving: When shifting the gear lever from D to S, it only provides an electrical signal. The transmission control system receives this signal and then adjusts the gear output ratio accordingly. 2. Shifting from N to D or R requires pressing the brake: N is the neutral gear of the car. The engine's power is directly transmitted to the transmission. If the car is started without pressing the brake, it will move forward or backward immediately when shifted into D or R. In case of an operational error, it would be difficult to react quickly and brake, thus still posing a risk of accidents.
I've been driving automatic transmission cars for many years, and shifting from D to S gear usually doesn't require braking. S gear is the sport mode, making your car more responsive with quicker gear shifts and acceleration. As long as your speed is steady while driving, you don't need to stop; just gently move the gear lever over. If the car is coasting or going uphill, the operation is even safer. Don't worry, this design is meant for convenient dynamic switching. But remember to check the user manual, as details might vary slightly between brands like Toyota or BMW. Maintaining this operation habit can reduce vehicle wear and enhance driving pleasure.
