How Does the Shift Lock Button in Automatic Transmissions Work?

[Beatrix]

After shifting into P (Park) gear, it is impossible to shift into other gears without pressing the brake pedal. This is a safety feature designed by manufacturers, where the shift lock solenoid circuit is connected to the vehicle's computer. When the brake pedal is pressed, the computer signals the solenoid to unlock, allowing the gearshift to other positions. Below is some related information: 1. Automatic Transmission: As the name suggests, an automatic transmission does not require the driver to manually shift gears. The vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Typically, automatic transmission vehicles have six gear positions, arranged from top to bottom as: P (Park), R (Reverse), N (Neutral), D (Drive), S (Sport), and L (Low). 2. Fuel Consumption: The engine's power is transmitted through the transmission, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume over 10% more fuel than manual transmissions. Whether manual or automatic, transmissions with more gears tend to be more fuel-efficient.
