In an automatic vehicle, overdrive is always on by default. For most driving situations, you should leave it on. This allows your vehicle to use all of its available gears including the highest ones. Overdrive maximizes fuel economy and keeps NVH (noise, vibration, harshness) at a more tolerable level.

Is my car faster with overdrive on or off?
On or off will not have any great impact on drivability, but will affect mainly fuel economy. The purpose of the OD switch on an automatic vehicle is to limit the drive line speed to engine speed ratio to 1:1 or turn off the overdrive ability.
Does overdrive off save gas?
Overdrive gears reduce your engine speed, which saves gas as well. According to the Federal Trade Commission, you can save gas by turning the AC off when it isn't needed. Turn it off when you drive up inclines or hills to reduce the strain on your engine, or while you wait for a traffic light.
Can overdrive mess up transmission?
The transmission sits in the middle, absorbing it all. An overdrive gear can reduce engine wear and improve fuel economy, but only if it's used under conditions of light torque demand. ... Too much torque demand during deceleration can damage the transmission and clutch.
Does turning overdrive off give you more power?
Turning OD off made the transmission ride the gears longer before shifting, providing more power, allowing higher RPM's and decreasing fuel economy.
What are the advantages of overdrive?
Generally speaking, overdrive is the highest gear in the transmission. Overdrive allows the engine to operate at a lower RPM for a given road speed. This allows the vehicle to achieve better fuel efficiency, and often quieter operation on the highway.
What is the purpose of overdrive in an automatic car?
Whereas a vehicle will normally operate at lower gears with greater output and torque, overdrive inhibits acceleration and maximum power. The vehicle is considered over-geared or overdriven, making it so that top speed and performance are sacrificed for greater fuel economy and a more effortless driving experience.
Does o d consume more fuel?
OD stands for overdrive, or in other words being in one higher gear than you would normally be in. What this is used for, is when you are cruising at a constant speed. If you are using it correctly, yes, overdrive will save fuel.

Overdrive is an extra higher gear in your transmission designed to increase fuel economy and drivability in freeway or long steady drive conditions. ... The only time it may be advisable to drive with overdrive OFF is when you are towing something.
How fast can you drive in overdrive?
Overdrive helps when you drive at more than 50mph. Overdrive (OD) proves to be the highest gear during the transmission. All this arrangement happens in an automatic car. Furthermore, it will reduce the engine's RPM to the required road speed.
Should overdrive be off in the city?
You should drive with overdrive on almost all the time. It provides many outstanding benefits such as lower fuel consumption, extending engine life, producing less noise, and much more.
What does o d off mean how do you turn it on?
The “O/D Off” button prevents the transmission from shifting into overdrive. This can be useful when towing a trailer, climbing a steep hill, or other situations where you don't want it shifting into the highest gear.
How do I get rid of OD on my car?
Locate the overdrive (O/D) button on the gear shifter. The overdrive button can be found on the left side of the shifter, below the button used to shift gears. It is much smaller but functions much in the same way; push it in to turn the overdrive on, push it again to release it and turn the overdrive off.
What does 4 speed automatic with overdrive mean?
It will mean that the transmission has four “obligatory “ gear ratios to move through, plus an auxiliary gear that will spin the gearbox output (driveshaft or half shafts on the front wheels) faster than the engine's crankshaft. This one, a cruising gear, will only engage when the torque demand is low enough.
