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 do you turn the overdrive on in a 1992 Lexus SC400?
It's usually on all the time unless you press the button each time you start the car. I think that normally the overdrive kicks in around 45 MPH.

Purpose of overdrive and to use overdrive for Hyundai Atos 1.0?
Over drive is always to reduce engine RPM at Med to high speed cruise thus saving fuel. If this is an Automatic car just ignore the Overdrive and let it work. If this is a manual car use over Drive when maintaining a steady speed and the car will not "Labour" to do so.
How does taking the car out of gear when driving on a downward slope affect the car?

What would cause your overdrive switch to not work on a 1995 Mazda Protege when passing a car and the overdrive switch is off it won't automatically shift down to accelerate?
If the overdrive switch is turned off then the car will not go into overdrive. As it is not in overdrive, then it will not downshift out of overdrive as it normally would. It also will not shift to 3rd gear above a certain factory preset speed. Turn th overdrive on and see if it operates normally.
What does the circle d on the shift column mean?
Overdrive. The transmission contains a final section that causes the output to turn at a faster rate than the input. When this happens it is refered to as "overdriving". Very common in new vehicles as once at speed the overdrive kicks in and the rpms become lower to keep the car at the same speed, hence increasing gas mileage. Press lightly on the accelerator and you can feel the overdrive gear kick out and the car then begins to accelerate. The circle d refers to overdrive gear in your transmission , which is less than a 1:1 or direct drive gear ratio. This gearing lowers your engine rpm for fuel economy but effects pulling power of your vehicle.In a truck there is normally an overdrive disconnect switch on the end of the shift lever.

What is overdrive for in your car?
Overdrive is almost like another gear for your transmission. Say you have a four-speed w/ overdrive automatic transmission in your car. Once you get up into fourth gear, and if you're not trying to accelerate hard, the trans will kick into overdrive. It drops the engine's RPM's and saves gas. When you are traveling on the highway it help to conserve fuel.
What happens to a car when overdrive goes out?
If the rest of the Transmission continues to function, then result is that the engine RPM's will be higher when cruising than is normal. Overdrive reduces the RPM's at the speed where it engages.
Using overdrive in on a vehicle?
Overdrive is the highest ratio gear in a vehicles transmission. It alows the car to travel at highway speeds and still keep engine speed low. In automatics it is used automatically, however you can push the button that says "overdrive" and it will turn the overdrive off. This gives you more power but limits your speed and decreases your fuel economy and longevity of the vehicle.
What do you check after installing a kickdown cable in the transmission and throttle body but the car sounds like a lawnmower and still does not pick up speed until reaching 5000 RPMs?
Need more information... What year, make and model. Is it a 3 speed automatic ( TH350 ) or an overdrive (700R4). Does it have OEM carb or aftermarket.
