overdrive chooses the most fuel efficent gear but the savings will only be noticed on the highway. try not to use o/d when towing though, even on the highway. it's hard on the trans. YES!! Seriously? Just to add to the first two answers... Overdrive will kick in once the truck reaches approx. 55 mph. It shifts the transmission into a higher gear, which provides a higher output rotation at the wheels than the lower gears at the same input rotation/power. This translates into less work, and therefore less fuel consumption, to maintain the same speed. When the PCM determines that the truck needs more power rather than speed, it will downshift as needed. If you are towing, it will have to downshift more often, making for less fuel efficient operation. If you have a tachometer, glance at it as your transmission is shifting and try to track your RPMs as well as your speed. You will see that the RPMs actually drop when OD kicks in. The lower the RPM and the higher the speed, the more efficient the fuel consumption.

Can you Tow automatic transmission cars?

If its a light load, if it will be frequently used its worth getting a transmssion cooler to save the trannys life. Its also a good idea when towing to drive with the over drive turned off. Overdrive isn't meant to handle a load, just to freewheel to save gas on the highway. Towing a load with the overdrive on can burn out the overdrive.

Does the over drive make your car go faster or slower?

the overdrive is used to save gas. it is an additional gear after your final gear in the transmission. this gear usually kicks in at higher speeds (maybe 50+). you will notice the tach drop down about 500 rpm's as the vehicle kicks into overdrive. it does not make your car go faster or slower. you will not have be able to accelerate as fast in overdrive as you will in other gears. if it is an automatic overdrive then as you slow down the overdrive will automatically be taken off.

When to turn off overdrive in your car?

The overdrive should be switched off when you want to avoid unneccessary shifting. If you are driving on a hilly road, the vehicle will shift out of overdrive going uphill to maintain speed while pulling the vehicles weight up the hill, and shift into overdrive going down the hill to save fuel when additional engine power is not needed. When towing with an automatic transmission, the vehicle may tend to repeatedly shift in and out of overdrive due to the added weight. In scenerios such as these, you should turn off the overdrive to avoid the unneccesary shifting which puts more wear and tear on the transmission.

Do you drive your 1997 ford explorer with overdrive on or off?

it depends on where you are driving. If you are just driving around town, you should probably turn the overdrive off, because it will cause the engine to run at very low revolutions per minute, which is not good for it. If you are driving on the freeway, then you should have the overdrive on, because it will save you fuel. However, if you are in hilly terrain, turn the overdrive off, so that the engine will be running fast enough to climb the hills without the vehicle slowing way down. Practice turning the overdrive off just before you start up a hill, and give the vehicle the gas to get its speed up before you get to the hill. This way, you can maintain freeway speeds. When you reach the top of the hill, turn the overdrive on again. Most transmissions today are set up to shift up as quickly as possible, even around town, to make them seem more fuel efficient. I have had a vehicle shift into overdrive at 20 miles per hour, but as soon as I gave it a little gas, it would shift down again, usually a couple of gears. Consistantly driving an engine at low RPM's results in carbon deposits in the engine, fouling of anti-pollution equipment, and poor gas milage. By turning the overdrive off in town, you can help to prevent these effects, and save yourself money on garage bills.
