Im not a engineer so ill let the pros answer that:
How stuff Works
But i know when u should use it, it best used on the freeway or higher paced traffic. When your car is revving low, and you want to pass someone, click the overdrive button and accelerate, when ur done passing click it back off. Notice that ur car gets louder when u press the button, its engaging the engine without the torque converter, like a manual.
Have fun.

i dont have a button... but when i floor it the sound goes from a lower sound to a high pitch whine and jerks the car super quick ive taken on v6 accords this way, is this overdrive?

Typically, the third gear in an automatic car is at a 1:1 ratio, (no reduction) while 1 and 2 are both reduced. 4th gear is overdrive which is a gear that is higher than 1:1 (.70:1 or so) which means your engine doesn't have to rev as high and use as much fuel on the highway.

On five and six speed cars, 4th is the 1:1 gear and both 5th and 6th are overdrives.

My inline 4 accord has an overdrive button on the shifty knob thing, i think. There's a button you can press for "Sport" mode.

your car is down shifting into a lower gear so that them motor is revving higher adn will pull harder.

Overdrive is just an extra gear (like a fifth gear) designed for cruising. After you're already going fast... it doesn't take as much energy to keep it going... so Overdrive doesn't offer a lot of power, because it's geared so low (keeps the RPM's low).

Pressing that button (if you have one) disables that extra gear and only allows use of the first four gears. Sometime you shift the shifter into 4 rather than D.

Overdrive is like the smallest gear on your 10-speed bicycle. It's only for use when you're at-speed (cruising).

It's normally a good idea to turn the Overdrive off when you're going up a big hill so that you don't jump from OD to 4th to OD to 4th again and again and again.


Dig it?

Technically, drive is the 1:1 gear, and overdrive is the gear that is a higher ratio than drive, hence "overdrive."

Honda never has button for overdrive except on the CR-V! The "Sport" button is not the overdrive button! Toyota and Nissan has overdrive button on the shift knobs! Basically if you are driving in D4 (Honda only), you are using overdrive! If you are driving in D3, the overdrive is off so you would never reach 4th gear! With Toyota, you have to turn off overdrive by pushing the button on the shift knobs!

My contour is the same way, a button on the shifter and a light on the dash. When the light is lit (O/D OFF), fourth gear is unavailable.

bachviet

ALways drive with 4th gear unless you are driving in traffic and below 45mph @ most of the time! You will waste more gas in 3rd gear!

joe52985

wow i am confused! d4 is the gear i am always in so i am always using overdrive? i only use d3 when its dead stop traffic, what gear should i be in?
d4
d3
2
1

should i always be in d4?


(side note) cut off a viper today going 120 on the highway pissed him off sooo bad

palayah8ta

Hahahah, i hope u said sorry.

Burzhui

so hold on when you start the car, in the city, do you unclick the button, som you get a green light saying o/d off...or do you leave it as is?

omg, i am so glad i drive a manual transmission car

there are no buttons to push, you just shift to the appropriate gear when required.

I'm second to that! Traffic is way too much to bear here in SoCal. It took me from 30 to 45 minutes to drive 14 miles from home to work! I rather drink coffee or capuccino than shifting myself to death!

joe52985

the only minor detail there was that he was doing the speed limit, big deal!!!

whitak24

my buick has overdrive, drive, 2, and 1 on the shifter. no buttons or anything else. i just always put it in overdrive. if it doesn't NEED to go into overdrive when i'm going slower, it doesn't. it stays in 3rd. but that way i can run at consistently lower rpms and save gas. none of this shifting when i hit a certain speed for me.


but oh how i wish had a stick.....

DankNstickY

its not a bitch if ur good.

DankNstickY

yeaa... thats true.

i do wish that my car would turn into an automatic sometimes...

styleee

i live in a city, where there is always traffic, and its not a problem for me.

and i would much rather have a stick in hilly areas, you get to decide when to downshift... not waiting for your car to figure out that its not going anywhere.

brain

I don't necessarily think that is something to be proud of. Cutting off people at 120mph is an extremely dangerous proposition.

JPR

Every vehicle I have owned was a stick. Depressing the clutch is second nature now a days and I dont even give a thought. When I do drive an auto I feel uncomfortable for some reason. I miss the control a manual tranny gives.

Now that you know what overdrive is there is only one other important thing to know. The "R", that stands for racing. Next time you want to have some fun with the car next to you at a red light just drop it into "R" for racing mode.

What about "N" for Nitros?

Yeah, like on the 405 at five o'clock.

i read the manual on my 93 camry v6...overdrive adds a 5th gear when it is on..it changes the transmission from a 4 speed to a 5 speed...so i dont see why you shouldnt just leave it on all the time...it wont get used unless u go at high speeds

also, i might add that in the lexus rx300 the button on the shifty thing turns the overdrive OFF, meaning it is normally on by default
