What does O/D off mean in my car?

O/D off stands for Overdrive Off. This is a feature found on many cars that allow you to adjust the gear ratio of your car's transmission, allowing it to shift more quickly between higher and lower gears. When this feature is turned off, your car will shift into higher gears sooner while accelerating, resulting in improved fuel efficiency but, at the same time, sacrificing some power. It is important to note that this feature should only be used when necessary and not on a regular basis, as it can cause your transmission to wear out prematurely. Be sure to consult your car's manual for further details regarding the proper use of O/D off.
