Automatic Transmission Car: Put in Neutral When Stopped
Introduction
Automatic transmissions have become increasingly popular in cars due to their ease of use and convenience. However, there is some debate over whether it is better to leave an automatic transmission in drive or neutral when stopped. This article will explore the advantages and disadvantages of both options to help you make an informed decision.
Advantages of Leaving Automatic Transmission in Drive
* Convenience: Leaving the transmission in drive is the most convenient option, as it eliminates the need to shift gears when starting and stopping. This can be especially beneficial in stop-and-go traffic or when driving in hilly areas.
* Fuel efficiency: Studies have shown that leaving the transmission in drive can improve fuel efficiency by up to 2%. This is because the car’s computer can adjust the engine speed more efficiently when the transmission is in drive.
* Reduced wear and tear: Leaving the transmission in drive can reduce wear and tear on the transmission components, as there is less shifting involved.
Advantages of Putting Automatic Transmission in Neutral
* Reduced engine noise and vibration: Putting the transmission in neutral when stopped can reduce engine noise and vibration, which can be especially noticeable in older vehicles. This can make for a more comfortable driving experience.
* Prevents rolling: If you are parked on a hill, putting the transmission in neutral can prevent the car from rolling backward or forward. This can be important for safety reasons.
* Improved visibility: In some vehicles, putting the transmission in neutral can improve visibility by allowing the driver to see the brake lights better. This can be helpful in certain situations, such as when backing up.
Disadvantages of Leaving Automatic Transmission in Drive
* Increased emissions: Leaving the transmission in drive can increase emissions, as the engine will continue to idle even when the car is stopped. This can be a concern for environmentally conscious drivers.
* Potential for transmission damage: If the transmission is not properly maintained, leaving it in drive when stopped can put excess stress on the components and lead to premature wear and tear.
Disadvantages of Putting Automatic Transmission in Neutral
* Inconvenience: Putting the transmission in neutral when stopped requires additional shifting, which can be inconvenient and time-consuming. This can be especially problematic in stop-and-go traffic.
* Reduced fuel efficiency: Putting the transmission in neutral when stopped can reduce fuel efficiency by up to 2%. This is because the car’s computer cannot adjust the engine speed as efficiently when the transmission is in neutral.
* Increased wear and tear on brakes: Putting the transmission in neutral when stopped can increase wear and tear on the brakes, as the driver must use the brakes more frequently to hold the car in place.
Conclusion
The decision of whether to leave an automatic transmission in drive or neutral when stopped is a personal one that depends on the specific vehicle and the driver’s preferences. If convenience, fuel efficiency, and reduced wear and tear are important, then leaving the transmission in drive is the best option. However, if reduced engine noise and vibration, improved visibility, and preventing rolling are more important, then putting the transmission in neutral may be a better choice.
Additional Considerations
* Vehicle type: The type of vehicle can also influence the decision. For example, it is generally recommended to leave the transmission in drive when stopped in a hybrid vehicle, as this can improve fuel efficiency.
* Driving conditions: The driving conditions can also play a role. For example, it is generally recommended to put the transmission in neutral when stopped on a steep hill, as this can prevent the car from rolling.
* Personal preferences: Ultimately, the best way to decide whether to leave an automatic transmission in drive or neutral when stopped is to experiment and see what works best for you. There is no right or wrong answer, so try both options and see which one you prefer.
