Very elegant and efficient design, I'm glad I could help with the code :)

[@Texassince1836]

You can make 10 unique ratios with this, although if you leave one out you can get away with no double shifts in the same box (meaning no 1-3 shift) 1. 1,1 81:1 2. 1,2 45:1 3. 1,3 27:1 4. 2,2 25:1 5. 2,3 15:1 6. 1,4 (omit) 14.4:1 7. 3,3 9:1 8. 2,4 8:1 9. 3,4 4.8:1 10. 4,4 2.56:1 And if you shift 1, 2, 3, 5, 7, 9, 10 you never shift both boxes at the same time.

[@KastaRules]

Nice! Cannot wait to modify this into an Eaton Fuller 18-speed transmission.

[@leewhaen6157]

very nice and compact! im trying to design a 16-speed myself but i want the ratios to be in ascending order with no duplicates. to do this i use 1:9, 1:3, 1:1, 3:1 for the first transmission, and 5:3, 9:5, 25:9, 3:1 for the second. the trick is to use exponents of the same number for the first transmission (i.e. 3^x, where x can be positive or negative integers) and ratios that are adjacent to one another for the second transmission. just wanted to share in case it could help as ive always found your videos very helpful... also im very proud of my math and wanted to show off ;)

[@DAU-sx1rl]

Great Creation as usual! Hope you're doing well!

[@tamaslapsanszki8744]

Now this is a valid reason for me to invest in PF2.0. Great job Sariel, you are the best spokesperson/marketing expert LEGO Technic has ever had. Or maybe i should say you are the Lord and Saviour; The Way, The Truth and The Life; The Preacher of the Good News of LEGO Technic

[@tamaslapsanszki8744]

And then the Lord said: "Come forth and receive Technic instructions" But alas, the CITY and Star Wars fans did not believe in him. And there was much wailing and gnashing of 24 teeth gear Ok, I'll stop with the Bible puns

[@tuankiettran8811]

Update: I think want to make in customizable controls. try 2 buttons in different color. (+, -). And run the same program with different numbers (0 & 1) ect. 0 is a decrease the speed is -90° 1 is a increase by 90° When you press the + button, the gearbox will increase (1st to 4th). And when you press - button, The gearbox will decrease (4th to 1st).

Amazing gear box sariel

[@For891]

Even more useful then Yesterday’s post. Thank you .

[@dontwatchdis]

Here are all the gear ratios (First gearbox*second gearbox) 9:1*2:1 = 81:1 9:1*5:1 = 45.1 9:1*3:1 = 27:1 9:1*1.6:1 = 14,4:1 5:1*9:1 = 45:1 5:1*5:1 = 25:1 5:1*3.1 = 15:1 5:1*1,6:1 = 8:1 3:1*9:1 = 27:1 3:1*5:1 = 15:1 3:1*3:1 - 9:1 3:1*1,6:1 = 4,8:1 1,6:1*9:1 = 14,4:1 1,6:1*5:1 = 8:1 1,6:1*3:1 = 4,8:1 1,6:1*1,6:1 = 2,56:1

[@glowytheglowbug]

amazing design thanks for this!

[@techniclylego3563]

Really well made.

[@JediTim28]

Thanks...these are great for future builds.

[@thelastwoltzer]

It would be very interesting if you could make a working clutch out of Lego. Then if this is possible you can even make a I.C.E powered Lego vehicle

[@AtomicFile]

Am I missing something? I looked on the website for the parts list but didn’t find the parts list, I found the instructions though. I looked through the instructions and still didn’t find the parts list…is there one?

[@searme]

Page 3, the big yellow box.

[@JaceN3D]

Instead of using the spur gears for 3:1 and 9:1 gear ratio i will use 20 and 12 bevel gears and use 16 tooth gears where the bevel gears currently are so i can get more speed i will try that Idk we see 🤷🏾

[@antoniopineno205]

Maybe put two powered up motors and program them to go off at different times so you can get the 16 gears

[@Pilug404]

I’m building one that is also combinable but I’m trying to make it so it will shift the other transmission too

[@ildar9111]

Hello, can you please say how can I find part list for this transmission, could not find it on your web page

[@searme]

It's right there in the instructions file, in a big yellow box.

[@Wrutschgeluck]

hello Sariel, i bet the biggest problem for other is to find this special orange gear what you use. i cant find it in google or bricklink and also in your instructions there no LEGO part numbers to find it. Furthermore i found a mistake in your instruction pdf with exactly this part - you never build it in, it's just there at some point --> sariel.pl/down/3speed-servo-combinable-transmission.pdf between page 5 and 6 (same at 12 and 13). but its still impressive! awesome work and respect to you, that you don't do it for money :)

[@searme]

Yes, I thought it may be difficult for some to find this gear. Which is why I put a link to it right there in the video description.

[@Wrutschgeluck]

@@searme 🤦‍♂️

[@PinkiPai22]

Cool i like IT but i don't have that shift orange thing

[@searme]

Well, prices start at around 1EU: www.bricklink.com/v2/catalog/catalogitem.page?P=35188&idColor=4#T=S&C=4&O={%22color%22:4,%22iconly%22:0}

[@without.bounds.universe]

Hi, thank you for your video. I'm interested in buying your Lego builder's guide, but I have Control+ system. I'd like to know if you're going to add some info about Control+ system in your book?

[@searme]

Not in the foreseeable future, I'm afraid.

[@iamhugry]

Theres an issue im having, i go from 1st, 3rd 1st 2nd,

[@sailovspider]

Could be use here another new Technic motor like Boost external motor?

[@searme]

Yes, I believe the video mentions that.

[@sailovspider]

@@searme Thanks a lot, didn't have time to watch video intently, but will do it now. Great work!

Hello Sariel! I'm big fan in korea! I just want know which program do you use when you architech

[@searme]

MLCad and LPub.

[@Sukbang]

Thx!

[@gympee13]

Hi. What's the biggest model you could use this in?

[@searme]

Size is irrelevant.

[@rubien0389]

this is basically a motorcycle gearbox (just add a neutral and change the gear input)

[@Jachucreation]

Czy da się orginalne PF kontrolować telefonem Chodzi mi o odbiornik IR

[@searme]

Musiałbyś mieć telefon z nadajnikiem IR a chyba nikt już takich nie robi. A i wtedy niekoniecznie.

[@Jachucreation]

@@searme nadajnik IR posiadam w telefonie

[@searme]

No to szukaj apki która na coś takiego pozwala, bo ja nie znam.

[@roadwolf2]

Now to work out a low/high splitter unit so I can get overdrive gears

[@Texassince1836]

In a lego truck just make the axle a 1:1 ratio, that should make 16th tall enough to pull some speed

[@darabradley5173]

Would it be possible to make a tractor style 24 speed gearbox, 3 ranges, 4 gears for each and forward and reverse

[@searme]

Possible? Yes. Efficient? Hell no, not with LEGO gears.

[@Texassince1836]

Now put it in a lego truck and see how long it takes to get 5kg up to 5kmh

[@Chipster512]

Built it, one gear doesn't work under stress.
