Car Use: Automatic Transmission Overdrive
What is overdrive?
Overdrive is a gear ratio in an automatic transmission that allows the engine to run at a lower RPM (revolutions per minute) at highway speeds. This can improve fuel economy and reduce engine wear.
When to use overdrive
Overdrive should be used when driving at highway speeds (typically 55 mph or higher). It is not recommended for use in stop-and-go traffic or when towing a heavy load.
How to use overdrive
To use overdrive, simply shift the transmission into the “D” (drive) position and then press the “O/D” button. The “O/D Off” light on the dashboard will illuminate when overdrive is turned off.
Benefits of using overdrive
Using overdrive can provide several benefits, including:
- Improved fuel economy
- Reduced engine wear
- Quieter ride
Cautions about using overdrive
There are a few cautions to keep in mind when using overdrive:
- Overdrive should not be used in stop-and-go traffic. This can cause the transmission to overheat.
- Overdrive should not be used when towing a heavy load. This can put undue stress on the transmission.
- If you are experiencing any problems with your transmission, do not use overdrive. This can make the problem worse.
Conclusion
Overdrive can be a useful tool for improving fuel economy and reducing engine wear. However, it is important to use overdrive correctly to avoid any problems.
