Most people really get confused with the term overdrive. Some don’t know of it should be left on or off. There are still some people that will mistakenly press the button and then don’t know what to do afterwards.

First of all, let’s know the meaning of the overdrive in cars.

According to your mechanic, overdrive and OD for short is the highest gear in the transmission in an automatic car. It brings the RPM of the engine down at a given road speed to facilitate better speed and fuel efficiency. It also helps your car to provide the best performance in higher speed cruising.

For your normal driving, you should leave the OD switch on at all times. This will put your car in a mode that it will be able to automatically shift into top gear if necessary regardless of your selection. Leaving it on means that the ‘OD off’ light should not be on your dashboard.

Leaving the overdrive on will aid your car in utilizing its full range of transmission. It also helps your car with fuel efficiency and improved life span of your transmission.
