- How a Manual Transmission Works
A demonstration of the basic principle behind a constant-mesh manual transmission. The animation is loosely based on Toyota's 5-speed R150, and the 3D model it is created from is available on Thingiverse at www.thingivers...
I hope that the video is helpful and instructive for some.

I've watched a handful of these "how it works" videos regarding transmissions and they've all left me more confused than when I started. This one made things click for me. I really appreciate all the work you put into this! Thanks!
Thank you for telling me that. It is exactly what I had hoped to accomplish for someone.
@@johnsanborn2950 I have some questions about your transmission?
Here from r/cars, this video finally explained to me how a manual works.
Thank you for taking the time to let me know that.
that animation was so much more helpful than others i've seen
I agree with you
This is by far, best animation.
Thank you. I'm sincerely pleased that it helped you.
@@johnsanborn2950 is it possible to buy that model?
@@burnzy3210 The STL files for the model are available for free... www.thingiverse.com/thing:3776077
Definitely among the best explanations of manual that I've seen, and a fantastic 3D print to boot! Thanks :)
Thank you
This is the best illustration of a 4-speed gearbox I have ever seen!
Wow. That's very kind. Thank you. I'm happy that you found it worth your time. :)
@@johnsanborn2950 I think the thing that made this video better than most is how you removed many of the components to show how only the items that you were talking about were shown. Then after a clear insight into how the countershaft and the sleeves work you put them all together. Well done!
@@rudyyarbrough5122 Thanks again. That is how I prefer to be taught something myself. Start at the root and build it up for me.
This is one of the video, where I understood manual transmission clearly, thankyou for the video
Thank you for letting me know that!
I'm high as a kite and somehow this made me cry in joy, thanks
That was so well done! Most videos stop before they show the shifter assembly. Thank you John!
Thank you.
This is the BEST explanation I have come across. Very easy to follow. Please make one for automatic transmission, I have been struggling with understanding how automatic transmission works
Thank you for that very kind comment. I'm proud that I was able to advance your understanding. I do hope to make one for automatics once MY own understanding of them is clarified to the point that I'd feel qualified to do so. :)
Suggest reducing the music volume by at least 20%. I could barely understand the commentary at times.
Thank you. Yes - I botched the volume balance in more than one place. I have learned from that and will do the audio mix with more care next time. Frankly, I hurried the release. It had been months in the making - a daily grind of tweaks and retweaks ... when I finally glimpsed the light at the end of the tunnel, I ran to it. :) In post mortem I provided a customized Closed Caption track ... too little, too late. (For the record - one of the thumbs ups on your comment is from me)
Eliminate it completely and this will be a decent illustration.
Only thing missing is the synchros but I guess that's really best left for the next installment lol
this is like the best explanation of how a manual transmission works that i've ever seen in my life!!!
Thank you.
Thank you for taking the time to tell me that. I appreciate it. :)
Brilliant explanation, mate! Thanks very much. As another person pointed out, no music is cool :)
Thank you :)
Best video *BY FAR* of showing how manual transmissions work!!
Thank you for taking the time to comment.
For the first time I fully understand how a manual trans works, thank you!!
After watching so many videos of manual transmissions, I finally understand. Thank you very much for sharing
I'm proud that I was able to help. Thank you.
This video make me understand the transmission in just 6 mins. It help much.😊😊😊
Thank you for taking the time to share that.
That is the best presentation I have seen in Fusion 360. Absolutely fantastic job!
Thank you, so much.
Very clear and concise explanation. Great job guys!
Thank you
The best video about manual gear explanition
Thank you for taking the time to comment. :)
The best explanation of manual gearbox, thank you
Thank you for commenting. I'm very glad you found it useful. :)
The best animation on this subject out there.. Well done.. Before this video I couldn't work out what was going on..
Thank you for commenting. I'm glad that you found it helpful.
Very nice work and getting things to print with the right tolerances on a CR-10 is a challenge in itself. I fought that on a few stationary steam engines to run on air. First transmission I took apart was on a 1950 Plymouth to replace a broken synchronizer gear, at age 17, now 71.
Thank you for taking the time to comment. I was two when you took that first transmission apart. You didn't mention that it was ever put back together ;) My CR-10 and I have reached various agreements over time (I don't push; it doesn't shove). It's been extraordinarily good to me for the past year - a real workhorse, but yes - tight tolerances were the largest challenge here. And that shifter cradle...I'm still waking up in the middle of the night...
@@johnsanborn2950 No help as a kid without a father so I had to get it done on my own. Unheated single car garage in an Iowa winter.
Just replaced the hot end on my CR-10 as unattended I ended up with a ball of melted PLA
What did you have as a guide to do this project or just all on your own?
Can you adapt a small motor to spin the input shaft?
Just a great project!
@@gvet47 I have found the hot-end silicone sock to be a worthy, inexpensive, and painless modification. Highly recommend them now for just that eventuality.
This was done completely from scratch with plenty of missteps along the way. I actually began modeling a much simpler, older transmission (viewed in a 1936 Chevrolet training film titled "Spinning Levers" - look it up - a beautiful little production) - but decided, after weeks of work, to scrap that and, instead model this much more complex and (to me) interesting one. I had a lot of prior experience with video production - but almost none with the animation of a 3D model - so that took a bit of effort.
One could motorize it, to be sure. I was tempted to do that with an earlier model that I made of an open differential (www.thingiverse.com/thing:3592644) but decided in both cases that it would hurt more than it would help when using the model(s) as hands-on instructional tools.
And just so I can sleep in peace again: My arithmetic was bad. I was 5 when you tore down that gear box. :)
One of best explanation of working of manual gearbox.
Thank you. I'm glad that you found it useful and that you took the time to comment.
Oh my god, the mechanics are just amazing, and congratulations for the animation, I almost didn't understand it but I finally got it! Thanks to your animation, these things are very complex!
It truly is elegant engineering. Thank you for the kind words for the animation. Glad you found it worthwhile. :)
THE BEST ANIMATION WHICH HELPED ME TO UNDERSTAND!
Thank you for the comment. I'm so glad it helped!
This is amazing. Even the background music is mechanically epic.
Thank you. I'm glad that you enjoyed it. :)
Fantastic video. Thank you so much as Please do the clutch next but the music a little quieter.
Thank you. I am strongly considering the clutch as my next project. I'm experimenting with modeling the clutch fingers (as 3D printable and functional). If I can make that work, then it's game on.
After watching many many many videos, this video finally make me understand! Great!
Thank you. That makes me so glad that I did it. And thanks for taking the time to let me know.
Great explanation and also printable! What more can we ask for!
Thank you for that comment. I'm delighted that you appreciate the result. :)
Really good visual explanation I ever seen 👍
Thank you for commenting.
this is the best video ever.
wow. Thank you.
What a beauty of your demonstration!
Thank you for those kind words :)
Thank you sir you helped me a lot,thank you again 🙏.
You're welcome. I'm happy that you have found it useful. :)
Very good animation,very easy to understand
Thank you :)
This is really good. Thank you for the work you put into this Video. Now I'm not so intimidated if I ever need to do Transmission work!
Thank you so much for the comment. My only goal was to help folks who might otherwise be overwhelmed...It is nice to hear that the effort was worthwhile :)
Helpful, but I would have liked it if you had also explained how the clutch works with the transmission.
Thank you. I agree almost word for word with Tomas Beblar's response. I am considering modeling a clutch as my next project.
@@tomasbeblar5639 Words right outta my brain. :)
Wow fantastic!
I totally understand this mechanism works!
Thank you!
Thank you for the comment.!
Correction: "...understand HOW* this mechanism works!"
@@customfantasyhotwheels my english is pretty bad. thank you for your time!
Very cool! Thanks for making this, I had no idea. Now we need one for how the clutch works. Hint. 😊
I finally understood how this works. Thanks
Thank you for the kind words. I'm glad that you found it helpful. :)
2 years ago i took a course and we had to 3d print a gear box i used your design and saw this video, it was my first time to understand anything in engineering after 3 years in the school, its amazing how can you've this impact on so many people, bc i was the team leader of more students just like me but we all ended up understanding the concept, thanks for you
i wish you can send me the calculation you used for the design, if you still have them?
wow. That's so great to hear. Thank you for taking the time to share that. I don't have any of the notes/calculations that I used for the project any more, but I can tell you it involved several hundred hours of work in all. I learned quite a lot about designing gears, and a lot about printing them.
Bloody brilliant, informative and great to watch.
Thank you.
Super easy to understand. Thanks
Thank you. :)
this is very easy to understand about Manual Transmission!!
Thank you. That's great to hear.
I never saw a better exlanation of a transmission. And I saw a lot.
Thank you. That means quite a lot to me: That you found it worth watching, and that you took the time to say so.
@@johnsanborn2950 no Problem 👍👍
This is the best breakdown I have seen yet, thank you very much for doing this:)
Thank you for saying so. I was hopeful that some folks might find it helpful.
Excellent video. The best regarding this explanation!
Thank you for saying so. I'm proud that you appreciated the video. :)
That is brilliant! Thank you.
Thank you
WOW, very good explanation. Thanks
I'm delighted that you found it worthwhile, and thank you for taking the time to comment.
great animation!
Thank you :)
Absolute excellent - thanks!
Thank you for the kind comment. I'm delighted that you found it useful. :)
This animator is good, tank you
Thank you!
Great Video! very best I've seen on transmissions. I found the music a bit loud, I have hearing issues, and having your voice around the same volume as the background music makes it difficult to follow your voice. I am guessing it took a bazillion hours to produce this video? I'm not sure how I'd do it through Fusion.
Thank you for the kind words. I hope that those who might benefit from it can find it. I struggled mightily to find a balance with the music. Start-to-finish: the research, model, video, and illustrated assembly.instructions took a little over 1,000 hours. I feel like I have a newborn. :)
Great, really easy to follow!
That delights me to hear. Thank you for commenting. :)
This is such a good video.
I am a Korean university student studying in Korea.
As I was studying vehicle transmission, your video was very helpful, and I went to the site above and downloaded the materials you uploaded.
However, I don't know how to assemble these products.
Can I get a file that is all assembled?
I am using Inventor.
I am delighted that you found the video so helpful. Thank you for sharing that.
Included in the posting of the model is a document named "Assembly.pdf" which is an illustrated, detailed, step-by-step guide to the model's assembly.
It would be impossible to create a single 3D-printable file of the completed model as it comprises more than 70 individual plastic parts and a dozen bits of non-printed metal hardware (small screws, nuts, springs,....)
The background music in front is really great. If possible, could you tell me what music it is? thank you
Credits for the music appear at the end of the video. :)
@@johnsanborn2950 Ha, thank you. I was too busy commenting and didn't notice,
Awesome job designing, simulating, 3D printing, assembling and then sharing! Was you able to do the simulation in Fusion or was that done with different software?
Thank you. Yes, Fusion360 produced the basic animations of the model. The video actually incorporates 6 separate animations which were blended together (in various ways) using PowerDirector 365 - the program that also provided the graphics (titles, labels, arrows, etc...) and the soundtrack. If curious, here is a screenshot of the video's structure as seen from the POV of PowerDirector. You will see 12 layered tracks of video, 1 audio track, 1 fx track, and that top unnumbered track which is the Closed Captioning (kinda). Not visible in that screencap is the voiceover track as it doesn't fit on screen there. imgur.com/a/jqqPf5I
oops. Make that "incorporates 10 separate animations..." :)
Best explication ever.. Bravo ✌
Thank you :) :)
Awesome vid, but dang! Transmissions are crazy.
Why are most of the gear teeth on a slant? It’s to reduce the noise from them engaging.
Notice the teeth for the reverse-gear chain are not on a slant. So you always get that transmission whine when you’re backing up. Safety feature?
I believe it is a lot stronger for the high torque to handle!
@@thomasgagel But the reverse-gear ratio is typically close to that for first forward gear.
@@lawrencedoliveiro9104 I always thought that reverse was a direct drive from the engine, with the highest torque of any gear. I’m not sure though so don’t quote me! 😅
@@thomasgagel Direct drive would be the lowest torque. Remember that the gears in the gearbox are invariably reduction gears.
@@lawrencedoliveiro9104 isn’t reverse the exact same ratio usually?
fascinating
Good lord good explanation! (maybe turn down background music a bit?)
Thank you for the comments.
Dang, the quality on that is so much nicer than my attempt, though it's only my first. How much RPM can she handle? Mine survived full blast on a makita electric screwdriver, though it's rather sketchy as it's not quite balanced (too thin a shaft, not quite straight -> vibration)
I hadn't pondered that, but I would say it could spin rather quickly, but with no synchros...shifting would be... uhm... interesting. :)
@@johnsanborn2950 Mine has no synchros either. Well theoretically the pieces of plastic are there, but they get negligible friction to the gears, so they do nothing. As I don't have a shifter mechanism, I can just tilt the whole thing maybe 20-30 degrees and it will shift under full power. Apparently I only have 1 pic at hand, here: imgur.com/a/iIBKa4K
Awesome video. How do brakes work without destroying the transmission?
Thank you. The output of the engine is coupled to the input of the transmission by a clutch. When braking to a stop, the engine is disengaged from the transmission using this clutch. Although not discussed in the video (as it is not part of the transmission proper) the clutch is represented by the circular plate attached to the end of the transmission's input shaft.
That was very useful, thank you !
Thank you for taking the time to let me know that. It's great to know that it has been helpful.
This is the best
Thank you. Very nice of you to say.
Very good animation
Thank you :)
If all the 4 clustered gears are always in mesh and rotating with the counter shaft, how are the gears independent,?
The gears that they drive - the gears on the output shaft - are independent.
thank you
Nice! I wanna print one of these now! How much material did you use?
Thank you. The final prints took roughly 155 hours in total (using a single printer.) I would think that's something on the order of 1.5 kg give or take. (And many more times that in the design process)
Help full
I wonder what program do you use to design this type of things. I use Inventor of AUTODESK.
I used Fusion 360 to design the model and to create the animations (8 in total) that I then combined together using PowerDirector .
@@johnsanborn2950 Thanks for answering, you have a lot of knowledge about that program and I want to learn it because the people in general speaks well about it. Now I'm gonna try to do your transmission model. Greetings from Spain.
Amazing
Thank you.
Theres blueprints to make it on Solidworks?
hello friend good video a question
the reductions are the same in all the gearbox or vary according to the manufacturer and how can I know what they are, is there a page that says so?
greetings from Argentina
The ratios vary from model to model of gearboxes from different manufacturers, and they also vary within models from the same gearbox manufacturer depending on what the car manufacturer wants. There isn’t a standard set, although some ratios are very common. Very few car makers make their own gearboxes - they buy them from suppliers.
So what is happening when you grind the gears? I started driving manual only a couple years ago and I still will accidentally grind them shifting down into 1st once every few months.
Shifting down to first is pointless
This involves a mechanism called a Synchronizer (not covered in the video). There are a handful of decent UA-cam videos out there on the subject. Here is one that I favor... ua-cam.com/video/nM4CuWlnJY0/v-deo.html
Only select first when you’ve stopped. As long as the car’s moving, go no lower than 2nd, and feather the clutch a little if you need to, but only for an instant.
Can you do a video explaining how you made the animation?
Thank you for that question. I'm not sure how viable such a project might be. It would require several hundred hours to produce, and would have a relatively small target audience - those using both Fusion 360 and PowerDirector. But you have me pondering it....
Could not be done better
Dunno about that, but thank you for the kind words.
So why might car cruising (by cruise control) in 5th gear suddenly shift into 1st on its own, no input on the shifter (or any pedals) by the driver, and remain stuck there? Failure of a shift fork, or ?
Gear locking pins and spring/C clamp might be worn.
👏
Light bulb! Thank you!
lol. Well said! Thank you for commenting.
Hey quick question could you make it without using the bearing balls and the spring? If not is there any alternative?
It would still function w/o that hardware. You would only lose the detents that provide positive stops for the selector sleeves' key positions.
john sanborn ok thank you for the help. Looking forward to making it
i was wondering how you made those gears in fusion 360. i couldn't find a way to make helical gears with a controlled outer diameter. i tried add ons but to no avail.
I used "Helical Gear Generator" by Ross Korsky (available in Autodesk's App Store). I did not control individual gear diameters. I controlled each gear set's "Center Distance" (the sum of their two radii) - keeping this a constant. This is done by calculating an appropriate module for each of the four gear sets.
@@johnsanborn2950 thanks for the help you are awesome
Now I understand
