Thank you Peter for your very informative and helpful-to-me video. I tried changing overdrive to 'on' and 'off' (on my Isuzu Bighorn) as you portrayed, at various speeds, and it all worked out as you demonstrated. Please forgive the negative comments from folks who have never been overseas or never met anyone from beyond their local neighbourhood. And thanks to those prior comment- makers who encouraged new viewers to just listen; persevere; learn and not be unduly prejudgiced.
for everyone still confused, overdrive lowers RPM acting as an extra gear to save gas. at higher RPM your engine uses more gas to rotate it at the high revs. with overdrive it reduces the need for extra gas by slowing the RPM.
It's simple, this dude explains it like it's hard to understand. The input shaft turns (EXAMPLE) 2/3th turn as the output shaft will make a FULL turn that's all overdrive is. It will indeed save gas and make it more responsive/lively.
Pressing overdrive ON = Economy horse power. Pressing overdrive OFF = Increase horse power. Now I iunderatand fully and thank you for the important infos👍👍👍👏👏👏😁😁😁
Thanks for your time to explain the overdrive. Sure, it is a fuel saver and engine wear reducer. But my only use for the option of deactivating the o/d is while pulling a trailer. The added drag of the trailer changes the requirements on the transmission, in my case, to a point where the transmission at highway speed is always near the point downshifting out of o/d into 5th gear on my FJ Cruiser. This causes frequent shifts up and down just to maintain a constant speed on anything but a flat surface. Disabling o/d here makes for less wear on the engine and transmission by keeping it in 5th. And yes, if I would drive faster the drag increase might keep it in 5th. Or conversely slower driving may allow it to stay in overdrive.
Oh God, all along my understanding of overdrive was upside down. I would think that I am in overdrive when the lights on the dashboard were showing. Thank you teacher to open my eyes.
I also thought the same, know I know better. When the OD OFF light is showing on the dashboard that means you are in economy mode. (No need for much power) when you need much power you press the button to turn the light off, meaning you have enable OD for more power and high fuel consumption uphill.
*FOR ANYONE WHO DOESN'T UNDERSTAND* Turning off overdrive just stops the transmission from switching to 4th gear, therefore the revs will be higher since the transmission is still stuck at 3rd gear... And it's just usual knowledge that higher revs equals more engine power (Which is why people would want to use this feature). The issue with this is that while you are benefitting from the higher revs and extra power, the car is also using *much* more fuel compared to usual since the car isn't switching to the 4th gear
In overdrive there is a special gear that connect the engine with the wheels directly dismissing the transmission completely thus being very economical at the highway.
Thank you Peter for explaining this function so nicely. Well i got myself a 2003 landcruiser gxr (V6) in Qatar and was wondering what is this OD function all about. Thanks once again for this brilliant video.
If you're pulling a really heavy load, turn off O/D when going up hill if you need. It's like having a 5th gear. It allows you to go get much better economy. Think about how when you shift into a lower gear on a bike. It's a lot easier to do when you're already going, takes less energy than peddling second gear, and allows you to go faster, but hills are harder to get up unless you already have momentum. Same deal for the car.
Thank you for this sir! We recently converted our toyota corolla from manual to automatic and I have seen that overdrive button which I don't know what use it has until I watched your video. Now I understand why sometimes I can't accelerate that much because of the overdrive and I have difficulty on going to steep slopes/elevation. I'm going to try with overdrive off and see how it goes. Thank you!
How much did it cost to change from auto to manual? I'd like to do the opposite and change my automatic camry to manual, but not sure the cost is worth it lol.
+54sloth My Chevy has over 550,000+ miles. It's a 1990 Silverado 2500. It's been to Colorado, Oregon, and Washington a lot. Same engine. it can still burn out which amazes me.
By using overdrive (OD) off option, car gear will not shift from 3rd gear into 4th top gear to get more power (RPM) but at cost of more fuel consumption
I am so indebted to you. My O/D OFF light is on. I tried searching for my Camry manual and couldn't find it. I googled Camry Overdrive, and got you. I've had this old Camry since '07 and was not aware to this button on the gear shift until I found your video!
okay, I know NOTHING about cars, so I've been trying to get this concept into my head for a bit, tell me if I'm wrong, but: Overdrive is basically something you can use from the 3rd gear up usually, and it can keep my revolutions down while making my car push harder, so basically it is like switching to the hardest gear of a bicycle, right? except it's not me pedaling, but the engine?
To put it simply, pushing the button turns O/D off. All this does is disable the car from entering the highest gear. That's it. If you're automatic car has 4 gears, and the you push the O/D off button, the car won't shift above 3rd gear no matter how fast you go.
Thanks for the briefing the Over drive. i really don;t know about the button, but after watching your video, now i know what to do and when i need to use over drive. thanks peter
Wonderful explanation, i just today get my flash o/d off light on my Toyota Camry 2005 and i was so afraid if something wrong ! ,Now completely understood what that means , Thanks alot man
So it won't damage your car if you turn O/D on or off while driving. I have a 1999 Grand Marquis and have always left it on. Scotty Kilmer used my car in one of his videos too and talked about it.
So basically when overdrive off light( on dash) is on the car is gonna stay in lower gear(say the limit is 3th gear and not going to 4 th gear so higher rpm) and over drive on( light not on dash) it’s gonna go through all the gears (now it can go to 4th gear) to save gas and be at a lower rpm.
Sir, I have a question regarding driving an automatic transmission car on a 30-kilometer range uphill route. What is the best driving method to use? Should I use the OD (Overdrive) OFF function or gear 2, 1 or L gear? And to assist with engine braking, on downhill, should I use gear 2, 1, or L for the entire 30 kilometers to prevent damage to the transmission? Your answer and explanation would be greatly appreciated
@@PeterFinnTheCarDoctor but most of the mechanic say" if you use gear 2,1 or L for the whole driving uphill or downhill for 30 kilometer route it will damage your transmission" so they advise instead of using gear 2,1 or L you should use the OD OFF. Using gear 2.1 or L is only for a short range of uphill or downhill as they said.
Thanks a lot Peter! I appreciate you can give me a hint. My car with automatic transmission works very well when overdrive is OFF, But when overdrive is ON the transmission doesn't shift from 2nd to 3rd. if I apply more gas it get like slippage. Could you give me any idea to solve this problem? Thanks in advance
I really love this guy but recommend this to watch it with family at Saturday night ..don’t forget to turn on the captain or english automatic generator and some have snacks while watching,reading,eating and laughing 😂
What year is your Camry. I have a 95 but my OD off light won't come on. The OD on/off button of the transmission works because I can feel the car going into and out of overdrive. I think the light bulb is simply burned out. Also, your Drive light bulb is out.
hi peter, big fan of yours..i seee in the video you switching overdrive on and off while driving at 80mph.. isnt that bad for the gearbox as its making the gears and rpm to shift erratically? shouldnt you slow down below 30mph before turning it on and off? thanx
Do you accelarate while pressing overdrive or releasing the accelator before pressing the over drive button?, which is safe sir? Thank you for the positive response
Thank you sir for the time to reply. How about shifting gears sir from drive to gear 2? Do you accelarate while shifting gears or releasing the accelator before shifting gears? My worries on suzuki wagon when shifting gears might be the engine breaking that may wear out the tires and engine.
If on a congested traffic wherein you can only run at 40kph due to braking and accelerating often, does overdrive off save you more fuel because it is using more torque?
I drive an '09 camry, 2.4L, 5-speed auto. Generally if I'm under 55mph I keep O/D off (so gearbox stays inbetween 1st - 4th) for the best mpg. Otherwise, it will up-shift too early for best mpg. Do you agree Peter, or does the auto-gear box know best?
MEANS THAT ON NORMAL ROADS THE O/D OFF INDICATION SHOULD NOT BE SEEN ON METER. AND WHE WE GO THROUGH HILL OR STEAP ROADS THE O/D OFF INDICATION LIGHT SHOULD BE SEEN ON METER.
My 98 Corolla has just hit 100K and the engine is so smooth. But let me get this straight...Turning off your overdrive is like turning on Sport right? Will it harm the car.I always have it on.
keep the transmission in lower gears for more rpm, might make it faster too since you dont have to wait for the transmission to drop gears when you push the gas.. also helps on hills to slow down with engine
L is first gear. Your car will stay in first gear. I never use. 2 is second gear. Your car will only be able to shift between first and second gears. I sometimes use going down a steep hill. It will allow the engine to do your braking. D is Drive. Your car will use all three gears and overdrive if the button is on.
Just going by my experience driving with over drive on/off. I think with over drive off it gives you more torque and with it off it gives you more acceleration. So by my understanding when you are off the highway don't use overdrive and when on the highway use it. Is that right?
Hunt Guy you can use it to lower the revs on your engine when cruising at a constant speed and to make the transmission brake you harder when you release the accelerator pedal.That's all you should use it for.Accelerating quickly should be done without overdrive and generally applying more power to the wheels should be done without overdrive...
Great video ..So my 06 auto struggles a bit on the big hill that traffic can go at 60mph on, I'm doing like 42mph flat out until i reach the top and get on the flat road🤣should i try it with OD off ? Tia
basically how i see it, is youre trying to engage 4th gear. in D, you are only using 3 gears. (2 and L are 2 and 1) So with overdrive ON you save gas a bit? If so its a bit confusing youre now using 4th gear
Baka Ch hm ok, so i imagine the reason behind it is maybe the computer? basically by the time you have hit say 4th gear traveling at a faster speed, that means you just maxed out the cars power maybe? so now its not working as hard to get to the 4th gear since its already in it and you can cruise if you want now at a certain speed, meanwhile saving gas. correct?
Sir my over drive function is not working I install new 5afe auto engine in my car. Everything properly working . Where what could be wrong . Kindly ur suggestions. Thanks
I have three questions, first does Off give more acceleration from 0-30 km/h for example? also is the maximum horsepower stated in the car manual with overdrive on or off? How is the speed the same with more power? (when it increased 800 rpm) Answer what you can and thanks!
Yes it gives more acceleration because it changes the gear more later with higher revs making the car accelerate faster, than what it would be in the next gear slowly accelerating. The Horse Power is a mesurement of how much energy the engine can produce, 1 horse power = 746watts, so the horse power stated in the manual is the limit of the engine, the overdrive (on/off) option will only make you reach that limit number of horsepower (faster or slower) but it will not give you more horsepower. You will eventually reach the limit and thats the top you can get, so it only changes the time it will take you on eaching the horsepower limit. So it doesnt matter if its on or off the horsepower will always remain the same. The speed is not the same with an increase of 800rpm, you get more torque and that gives you more acceleration. Torque is needed to climb faster or reach a certain speed much faster
There is not one video about overdrive that i could find for now, on manual transmission, so i will be simple; its engaged in final gear, 5th,6th... you get the idea.
I'm a Automotive Diesel Mechanic trucks work similar but horse power/RPM and road conditions have a bearing on the fuel consumption most trucks have auto trans against the road Ranger manual transmission of my day..
One question, I am pulling a trailer for 3 hours trip , is safe for the engine of the jeep to go for that far in around 80 kmh with the Overdrive off ?
Peter Finn ok thank you very much is my first time pulling a trailer and I was worried about to go all the way with Overdrive off and in 3 gear for 3 hours. Thank you again for your help
Hi nice video, My car is a Toyota Camry 2003 Altise, it is unable to shift into overdrive (4th gear) - but shifts to gears 1-3 perfectly. Please help thank you
I always figured that it was a 5th gear for a 4 speed automatic transmission that you could turn on or off when required. The car I drive now (4 speed automatic) does it on its own - there's no button - and it feels like a gear change. No I'm really confused ...

Overdrive off (o/d off) keeps the car at third gear. The rpm is higher because of the smaller gear. You killing the car if you go over 60/80.

Hello Gentlemen
You give a very impressive knowledge.
I want to know
What is use of 2 and L mode?
keep the transmission in lower gears for more rpm, might make it faster too since you dont have to wait for the transmission to drop gears when you push the gas..
also helps on hills to slow down with engine
L is first gear. Your car will stay in first gear. I never use.
2 is second gear. Your car will only be able to shift between first and second gears. I sometimes use going down a steep hill. It will allow the engine to do your braking.
D is Drive. Your car will use all three gears and overdrive if the button is on.

Ok, Thanks!
Having O/D off and traction off gives the its max potential.

So going uphill you turn off overdrive? In a 6% grade hill
Does switching O/D on and off while driving cause any harm to the transmission?
No.

Overdrive is good when conserving gas, but if you're going up a large hill, towing, or at a dead stop, normal gear is the best.
Right, Thank You 😃

So with overdrive ON you save gas a bit? If so its a bit confusing youre now using 4th gear
+DjStiv3 Hello and Thanks for comment.
Peter Finn
but if youre using 4th gear now, how are you saving gas? you would think sticking to 3, staying in 3rd would conserve power, no?

hm ok, so i imagine the reason behind it is maybe the computer?
basically by the time you have hit say 4th gear traveling at a faster speed, that means you just maxed out the cars power maybe? so now its not working as hard to get to the 4th gear since its already in it and you can cruise if you want now at a certain speed, meanwhile saving gas. correct?
Sir my over drive function is not working I install new 5afe auto engine in my car. Everything properly working . Where what could be wrong . Kindly ur suggestions. Thanks
Maybe some wire or sensor connector is disconnected or damaged there
what kind of car is that with 400 thousand miles? I have a Toyota Camry I hope I can get that many miles on mine!
That's Kilometers.
Its about 250K miles
+TheRadTrav thanks for your reply
I am slighty over it with my s10 257k miles
cool
I have three questions, first does Off give more acceleration from 0-30 km/h for example?
also is the maximum horsepower stated in the car manual with overdrive on or off?
How is the speed the same with more power? (when it increased 800 rpm)
Answer what you can and thanks!
Yes it gives more acceleration because it changes the gear more later with higher revs making the car accelerate faster, than what it would be in the next gear slowly accelerating. The Horse Power is a mesurement of how much energy the engine can produce, 1 horse power = 746watts, so the horse power stated in the manual is the limit of the engine, the overdrive (on/off) option will only make you reach that limit number of horsepower (faster or slower) but it will not give you more horsepower. You will eventually reach the limit and thats the top you can get, so it only changes the time it will take you on eaching the horsepower limit. So it doesnt matter if its on or off the horsepower will always remain the same. The speed is not the same with an increase of 800rpm, you get more torque and that gives you more acceleration. Torque is needed to climb faster or reach a certain speed much faster

Thank you!
UnboxViews having it off saves gas?
is it recommended to turn on while driving or should you come to a complete stop?
Hi, please keep it always On.
Best explanation. Thank you.
Glad it was helpful!
Good info.! Thanks
Good info 👍😃
Will engaging or disengaging the overdrive while the car is at high speed damage the transmission system?
Yes, it could hurt the system.
Peter Finn no, it's just like down shifting when you step on the accelerator a little more.
very good explanation
+Nazmul Haque Thank You for your comment. :-)
with overdrive ON, what is your RPM at 70mph? you do have a 4 speed with overdrive automatic transmission, right?
70 mph and revs about 3200 rpm
And have a nice day to you, so wholesome 😭🥺
Noted 👍
So are all the cars in overdrive as default and if the "o/d off" lights on, they will have less power?
O/D Off is like More Power
There is not one video about overdrive that i could find for now, on manual transmission, so i will be simple; its engaged in final gear, 5th,6th... you get the idea.
Your last gear should be direct drive....not over-drive
@@MichelLinschoten no your direct gear cant be the last otherwise you'll be driving at Max rpm at top speed
Is it safe switch OD on/off while in motion?
Yes
It just doesn't use the 4 th dear when o/d is off .... use it for steep hills towing etc. .It's not like sports mode on dsg
Hello, Thanks for comment. :-)
@@PeterFinnTheCarDoctor I need help with a ttvi engine
I'm a Automotive Diesel Mechanic trucks work similar but horse power/RPM and road conditions have a bearing on the fuel consumption most trucks have auto trans against the road Ranger manual transmission of my day..
Ok
Amazing
Thank you! Cheers!
One question, I am pulling a trailer for 3 hours trip , is safe for the engine of the jeep to go for that far in around 80 kmh with the Overdrive off ?
With trailer pull, no not use overdrive.
Peter Finn ok thank you very much is my first time pulling a trailer and I was worried about to go all the way with Overdrive off and in 3 gear for 3 hours.
Thank you again for your help
what ever you do dont turn on CC
I thought that it was a good idea.
+- “iVanhs” - Hello and many Thanks for comment. :-)
Hi nice video,
My car is a Toyota Camry 2003 Altise, it is unable to shift into overdrive (4th gear) - but shifts to gears 1-3 perfectly. Please help thank you
Ok, interesting. Please replace transmission oil, it might help. You might have worn out clutch in gear 4th
Did you find out the problem with the overdrive?
bug efforts, thanks a lot
Well explained
Good call!
Good video
Thanks for the visit
So basically overdrive is more efficient and stays in higher gears but overdrive off gives more power stays in lower gears
Thank you Peter.
Dritan Bega Thanks
Thank you Peter!
Many Thanks for comment. :-)
Thank you.
You're welcome!
Why does my car shake at 40 mph/1500 rpms when overdrive is ON!? When overdrive is off this shaking doesn't happen.
In case you ever wondered what a Finnish accent sounds like, now you know...
1.25 playerback speed
OK physically what is overdrive and mechanically how does it work with the rest of the gearbox?
Thank You for info. :-)
that was a question
lmao
found the diagrams. thanks.
I always figured that it was a 5th gear for a 4 speed automatic transmission that you could turn on or off when required. The car I drive now (4 speed automatic) does it on its own - there's no button - and it feels like a gear change. No I'm really confused ...
thanks peter
