Hao Nguyen so many year on schools, hi schools, drive learning courses, nobody evere tried to explaine how gearbox works. Today i also realized how simple though cleverly designed a gearbox is. So many years they show us some gears, the clutch and never bothered to describe the way things works. Maby it was too smart for them. very nice video.
In modern transmissions, there's one or more synchronizer "rings" in between dog clutches and main shaft gears. When the dog clutch is being moved towards main shaft gear, synchronizer gradually applies pressure to the main shaft gear before the gear is actually engaged, thus synchronizing the speed of the input and output (and prevents the dog clutch from missing the gear). Synchronizers are like clutches inside the gearbox. If they wear out, you'll hear grinding sound when you're shifting.
ive been wondering how gears work and searched for it on the google (before i learn how to drive) but i always end up in not-so-clear articles about it.. And now finally!! I found this video and it is indeed helpful for people like me to understand how it works! Thank you for making this video!!
Finally a video that explains it all connected! I was watching videos on what a clutch was, and they all talked about how it functioned without telling about what it actually did with respect to the rest of the car. Thanks, it was a great explanation.
This really is fantastic, I'm always curious about this stuff and you guys do a fantastic job showing how it all works. Really amazing work guys, and thank you.
Thanks! My trade is electronics, but I generally am curious about how everything works. Fundamentally, I am appreciating engines because of how simple the concepts are
My trade is electronics too...how much have you learn so far...maybe we can share information...I'm still new to the trade...I'm thinking about getting an electronic lab kit but the one I want is pretty expensive.
I have an assosciates degree. I've done basic circuit analysis and assembly, soldering, programming in C, assembly language, and basic. I've done a lot with arduino too
This is one of the best videos of a 5 speed transmission I've seen if not the best I hope you make a clear video of an automatic as well this is very useful in understanding the power-flow from the engine to the differential. Keep up the good training videos. Great job.
I've watched a few videos on here on how the gearbox works, and how the gears interact, and finally I understand. Great video, the best on the subject.
Really Fantastic animation video for the explanation of transmission right from the engine to the differential and it cleared all the doubts that I was having in between...
You are not good but a excellent teacher . First time I have learned in detail how clutch , gear , engine mechanism works . God almighty bless you with more knowledge and expertise .
Thank you for your wonderful response. We are trying consistently to simplify most of the complex automotive systems. If you are interested to learn more, you can visit the Autopedia section on our official website. Do share your suggestions on our social media channels as well. Thank you!!!
I am confused about 1 thing: At the 2:16 mark, the video reads, "The main shaft gears do not transmit the power to the main shaft, as they are mounted over the bearings." Therefore, the gears are ALWAYS rotating, but do not transfer their energy to the main shaft until you engage the gear with the dog clutch. My question is: what does the dog clutch do to the gear in order to force the gear to transfer its energy to the main shaft? Does it lock the bearings in place or something? The video is not clear on this point. If anyone can explain, thanks.
Oops, never mind. I just figured it out. I did not realize that the dog clutch rotated. So, I assume that the dog clutch is on grooves on the main shaft, which allows it to slide side to side. However, when it rotates...it rotates the main shaft. Am I correct?
Good video, although with most traditional 5 speed transmissions, 4th gear is normally not a gearset as such and is actually just the input shaft and mainshaft locked together with a coupling unit, to achieve that 1:1 ratio. For this reason 4th gear is also the most robust as it's 'straight through' the gearbox. And 5th is generally an 'overdrive' gear meaning the output shaft spins slightly faster than the input.
THANK YOU GUYS SO MUCH!!! This is THE best video I have found on it, and now I actually understand it. More people need to make videos with these animations
I'm a girl , I'm taking driving licence and I wanted to know what happens inside the car when I press pedals and this video helped me soo much. Thank you! :)
Wow. Thanks for the quick reply. No need to apologize. Great Video! I don't know who you guys are but now I'm going to find out and use your services. Honesty and admission of mistakes is a rare thing in this world.
very good animation. not totally 100% accurate. but it does give a very good basic understanding. look forward to more vids, very good channel; great to see interesting mechanical concepts being clearly illustrated clearly via the clever use of animation. keep up the good work
thank you so much, I was trying to figure out how to make a small wind up tank to turn and drive forwards, your description of the flywheel is a life saver. THANK YOU!!! Now I can sleep well tonight, knowing the answer to my question.
THANK YOU VERY MUCH! I was looking all over youtube for a good animation on how a car works and this is the only one that explained how the car actually works, as opposed to just the motor. Good job and keep it up!
Good job, I like the way you start with the engine to show where the power is coming from first then move on to the transmission. I'm going to start doing that with my videos on real cars to give viewers context, great technique, thank you again for another great video, I learn something new ever time and take another little bit to add to my channel. Keep up the good work, we appreciate it!
Thank you for your feedback! We apologize for that differential error. Kindly, let us know if there are more. Your feedback will help us to rectify such errors.
Very, VERY nice.... Now, finally, perhaps I can with this vedio, explain to my wife the function of the clutch and why not to be timid as to "SHIFTING".....!!!! THANKS for putting this together in an easy to understand fashion. ..! Gordon in Maui
+Jean DAVID that's why there is an idler gear, to enhance torque,but at the same time increase the speed of the reverse gear by using a bigger layshaft gear.
+Kaan Yuce Imagine that the blue gear has 20 teeth, the idler gear 5 and the red one 10. When the red gear spins 100 times, the idler gear will spin 200 times (For earch rotation, the idler gear will spin 2 times) and the blue gear will spin 50 times (for every 4 rotations of the idler gear, the blue gear will spin once). So shorter: for every 100 rotations of the red gear, the blue gear spins 50 times, wich is consistent with the ratio between their number of teeth. The point now is that this ratio stays the same no matter what size the idler gear is. Take for example 40 teeth on the idler gear. The transmission the is: 100 -> 25 --> 50. So the size of this idler gear does not have any nett influence on torque nor speed. The only function is to change the way of rotation. So in addition to Jean David, the ratio between the blue and red gear in reverse schould be indeed around the same ratio between the gears in fist.
The clutch pedal doesn't necessarily make everything stop. Pushing it down disconnects the engine from the input shaft of the transmission, but the output shaft is still connected to the differential and the wheels. So if the car is still rolling, the shafts and gears inside the transmission are turning, just not necessarily at the same speed as the engine. That is why it is helpful to match your engine speed with your transmission speed before letting go of the clutch pedal and reconnecting the engine and transmission.
Excellent graphics and breakdown, I just randomly wanted to absorb some knowledge and this video was perfect for just that... THANK YOU & HAPPY NEW YEAR!!!
Wow Now I know why my my boss at the workshop got pissed as me when I said "When the car goes in reverse, does that mean the engine is spinning the opposite way?" I'm an apprentice
you are best man in the world because i didin't understand how gearbox work from any video on youtube but when iwatched your video i understod evry thing in a manul gearbox realy real thank you very much
I have been looking for a good video in order to understand how the transmission system works and i got it right now. Thanks a lot. You should prepare a video of how automatic transmission works or how cvt transmission works!! Thanks a lot.
Thank your for your response! It is highly inspiring to know that our videos are helping people in solving their doubts. Yes, TH-cam can be a great platform in providing education and that too in a very short period of time; and it is good to know that our videos are serving the same purpose!
You're the best at what you guys do keep up the good work and if you guys can make a video like this of how a carburator works i would really appreciate it thanks again great youtube channel btw 👍👍👍
This video was greatly useful to me in developing my basics about working of automobile transmission....I would recommend everyone to watch this video.
I've watching about 5-10 videos on transmissions on youtube over the last few days, and this is the first one that actually really breaks down how it works. I finally understand thow it works. Thank you for finally explaining for Joe Idiot how a transmission works
Greatly appreciated! You work totally to prepare this animation; it helps us to explain to others who are wondering about principles of transmission. Thank's.
EXCELLENT VIDEO !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! THANK YOU for doing this, i have never been this appreciative of online tutorials before
The ratio of the reverse gear is approximately similar or a bit less than the first gear to allow more torque, which is needed when the vehicle has to be moved from a stopped position.
Very effective video! I watched this just out of curiosity, and it kinda tweaked some of the misinformation I had about my Transmission 😅 #NeverStopLearning
This is the coolest thing I ever seen. Next to aerodynamics on a race car and downforce to provide a highly capable G load for stable cornering speed no matter what turning radius is required.
Great video indeed! The best amongst those I found here in youtube. One thing is not clear at the moment, which is how dog-clutches connect gears. I mean how their speed will get the same and their teeth connect smoothly?!?
Most "consumer" manual transmissions use synchromesh cone-profile rings to match speeds for smooth shifting. Dog clutches require a different (fast) shifting technique to avoid grinding, and are mainly found in performance or race cars.
Many times (especially when first learning manuel), they don't. This is the grinding sound you hear when you first learn how to drive a manual. The idea is that when the clutch is engaged, the transmission is allowed to spin freely. If you are in first gear, you must let the clutch out slowly and/or give the engine some gas so that the teeth engage properly. Since the car is already moving i.e. the tranmission is spinning when shifting into 2nd or higher gear, there is already motion built up...
The 1st time ever in my life, I understand CLEARLY how a car transmission works
Hao Nguyen nice to here that...

+jimis04 yes!!! i don't know why they teach us some useless boring shit like WW1 and WW2 instead of teaching us the real deal like this...
Best description of a transmission ever
Absolutely I agree
This is the best video on manual transmissions that I've seen, everything's explained so clearly. Thank you.
This is a demo of Double clutch gearbox and NOT synchromesh G/B
In modern transmissions, there's one or more synchronizer "rings" in between dog clutches and main shaft gears. When the dog clutch is being moved towards main shaft gear, synchronizer gradually applies pressure to the main shaft gear before the gear is actually engaged, thus synchronizing the speed of the input and output (and prevents the dog clutch from missing the gear).

Wow i never thought these concepts would ever be well explained , thank you ! Please keep making more !
I've watched many videos to learn how it works from the 'inside' but this one explains the whole thing in the most clear way
wow pictures do speak louder than words..... very nice and well paced tuturial
jammin music, clear diagrams and animations, concise language, i'd say this deserves a sub just from this video alone
We really appreciate the work you have done. its a great learning tool.

When my car was broken I start to investigate the basics of how some car parts works and this video helped me a lot. Thanks.
I am loving this channel, I'm learning soooo much. I am a new car owner and I find this information very valuable
Good luck. It's nice seeing a girl that want to learn about inner workings of the car.
Thanks! My trade is electronics, but I generally am curious about how everything works. Fundamentally, I am appreciating engines because of how simple the concepts are

Amanda Stahle If you find some valuable information please send it my way concerning my trade! Thanks!
I’ve seen so many videos on how the transmission works, none helped me to understand the mechanism as much as this video did. Great Job 👍🏼
Great video, please upload more such videos.
very elaborate video there. I have been trying to understand the gear system but all in vain, now i got it all....thanx to the author, job well done!
This is one of the best videos of a 5 speed transmission I've seen if not the best I hope you make a clear video of an automatic as well this is very useful in understanding the power-flow from the engine to the differential. Keep up the good training videos. Great job.

I hear this music coming from my roommates pc a lot.
I guess he really likes transmission diagrams.
PORN HE'S WATCHING THE PORN
this comment is underrated LOL
Really Fantastic animation video for the explanation of transmission right from the engine to the differential and it cleared all the doubts that I was having in between...
This helps a lot, I didn't quite understand how the dog clutch sends power down the main shaft but now I do!
You are not good but a excellent teacher . First time I have learned in detail how clutch , gear , engine mechanism works . God almighty bless you with more knowledge and expertise .
Best description of transmission system ever!
Even after watching so many videos on this topic, this video only explained me very clearly..... very great

hey guys, why aren't you guys uploading anymore?, your videos really helped a lot of us, i really hope that you guys will comeback.
😊I’m glad you created this video for us to watch and learn, it really helps me to learn about how the mechanism works.
I just learned more about cars in 10 minutes than I have in my whole life. Thanks for the great video!

Greg Ramirez I quite enjoyed the music.
Haha
Very clear visuals. I understood the whole mechanism only a single minute in thanks to them.
this video reminds me how informative youtube is.....,:: """simply awesome informative video. good job. thank you.

Amazingly informative. Thanks for sharing.
Great Explanation with animation all doubt clears.. Who is watching from India..👍
The size of the gears for reverse speed is not exact ! It must be the same as for the 1st gear for greater torque !
i like the video explanation
+Jean DAVID that's why there is an idler gear, to enhance torque,but at the same time increase the speed of the reverse gear by using a bigger layshaft gear.
+Jean DAVID Why didn't you mention the crankshaft phasing? :)
+Jean DAVID you are correct , the Size must be same ass that of the 1st gear (thumbs up)
+Kaan Yuce Imagine that the blue gear has 20 teeth, the idler gear 5 and the red one 10. When the red gear spins 100 times, the idler gear will spin 200 times (For earch rotation, the idler gear will spin 2 times) and the blue gear will spin 50 times (for every 4 rotations of the idler gear, the blue gear will spin once).

So in addition to Jean David, the ratio between the blue and red gear in reverse schould be indeed around the same ratio between the gears in fist.
I had a big curiosity about the differential portion, you made me clear. Many many thanks
Shouldn't the gear box be stopped while changing gears? I thought that was the point of the clutch pedal, to make it all stop.
Look again at 1:08 ;)
pantoner36 But when it was actually changing it was rotating. Look again at 2:54
Myntekt I know, I think it's a mistake it confused me too. :)
The clutch pedal doesn't necessarily make everything stop. Pushing it down disconnects the engine from the input shaft of the transmission, but the output shaft is still connected to the differential and the wheels. So if the car is still rolling, the shafts and gears inside the transmission are turning, just not necessarily at the same speed as the engine. That is why it is helpful to match your engine speed with your transmission speed before letting go of the clutch pedal and reconnecting the engine and transmission.
deltastvyt Well said. Its easy to make that mistake and its so often made by people.
In 6 minutes you understand the complicated transmission. Great Video! Thanks!
I will teach my dad who is the mechanic now
Excellent graphics and breakdown, I just randomly wanted to absorb some knowledge and this video was perfect for just that... THANK YOU & HAPPY NEW YEAR!!!

+TheAnt 777 damn, I hate it when people scold you for asking questions. How else are you gonna learn? Pretty hilarious question though.
ok ok Yea, it was in my second week so I didn't know much
+TheAnt 777 It actually does work that way in huge two-stroke diesel ship engines though!
The best explanation of a transmission I've ever seen.
Funky music.
Understood the mechanism only now. Brilliant way to explain.
you are best man in the world because i didin't understand how gearbox work from any video on youtube
but when iwatched your video i understod evry thing in a manul gearbox
realy real thank you very much
What I've seen, this is the best explanation of how manual transmission works.

Good work! The animation helped me. The gear selection clarifies so well.
nice clear animation of how a car manual transmission works....great video!
really awesome.... detailed explained.... now my doubt how power is transferred from engine to road wheel is clear... thank you so much....
The ratio of the reverse gear is approximately similar or a bit less than the first gear to allow more torque, which is needed when the vehicle has to be moved from a stopped position.
seriously, keep making those good videos! I learn a lot from them and they really improve my understanding in class.
Great Job!
Very effective video! I watched this just out of curiosity, and it kinda tweaked some of the misinformation I had about my Transmission 😅 #NeverStopLearning
The best video I’ve seen so far on the topic
I'm leaning how to drive manual transmission and found the animated diagrams in this video quite helpful!
you have change the way we learn , you explanation and idea are excellent . thank you very much for your tutorial
Excellent work, even a novice can understand the working. Thanks for quenching the thrust to know better.
this video is great, I need to learn stick before starting my new job as Aircraft Fueler July 11th. So this video helps a great deal, thank you :)
Clear explanation with proper animation 👏
BEST EXPLANATION EVER 👍👍👍👍👍👍👍👍👍👍👍👍👍
Excellent video and a very easy-to-understand mechanism. Thanks.
i love you , i watched like 1000 videos about tranmission and this is the first video i understood how it work, great explansion!!!
A big big LIKE. This is the best video about a car mechanism ever.
This is the coolest thing I ever seen. Next to aerodynamics on a race car and downforce to provide a highly capable G load for stable cornering speed no matter what turning radius is required.
Great video indeed! The best amongst those I found here in youtube.
One thing is not clear at the moment, which is how dog-clutches connect gears. I mean how their speed will get the same and their teeth connect smoothly?!?
best explination i have found so far . god bless your little soul.
Excellent crash course for automotive noobs like myself. Thank You!
Only video that explained it to me fully... Thanks.

Can't describe how much that was useful Thanks a lot :)
really great vid. totally answered all the questions i had about how a gearbox works
Awesome video. Clear explanation on gearboxes!
Timeless piece of information..
Very neatly explained..
