Engine braking with automatic transmission
Engine braking with an automatic transmission is different from engine braking with a manual transmission because the gearbox does not allow the engine speed to drop sharply.
Instructions:
1. Release the gas pedal: When you release the gas pedal, the automatic transmission goes into rolling mode. In this mode, the engine is disconnected from the wheels and the vehicle slows down due to air resistance and friction.
2. Shift to a lower gear: To increase engine braking power, manually shift to a lower gear (usually downshift). This will cause the engine to run at higher speeds, creating more drag and slowing the car down.
3. Maintain speed with the brakes: As you downshift, use the brakes to control the vehicle’s speed and prevent it from slowing down too much.
4. Switch off the gear (neutral position): When the vehicle speed has decreased to the desired level, switch off the gear. This will completely disconnect the engine from the wheels.
5. Resume driving: If you need to speed up, shift to a higher gear and press the gas pedal.
Advantages of engine braking with automatic transmission:
* Helps preserve brake pads.
* Reduces load on the transmission.
* Improves fuel efficiency.
Disadvantages of engine braking with automatic transmission:
* Less efficient than a manual transmission.
* May cause engine overheating if used on steep slopes for extended periods of time.
*Not as useful when driving on slippery roads.
Recommendations:
* Use engine braking only on level ground.
*Do not use engine braking as your primary method of braking.
* Avoid engine braking in automatic transmission mode as this may damage the transmission.
