How Manual Transmissions Work - A Simple Explanation

How do manual transmissions work? We'll learn how clutches work, how gears work, and how shifting works with a detailed explanation using a 5-speed manual transmission as an example.
Manual transmissions are without a doubt one of the greatest and most enjoyable automotive inventions. But how do stick shifts work? It all starts at the engine, where the flywheel transmits power to a clutch disc that's sandwiched between the pressure plate. The clutch disc is splined to the transmission input shaft, which rotates the gear assembly. A selector fork allows the driver to choose which gear to select, and power will then be routed to an output shaft and then a differential, ultimately reaching the driven wheels. Manual transmissions are super cool, check out the video for details as to how they work!

How its work for forklift transmission with 2 gear forward and 2 gear reversed?

[@dmajumdar2059]

Awesome video! I like you videos explaining basic concepts in great detail. Cheers!

[@juzoli]

Engineering Explained Wow, it was literally yesterday when I was thinking about, I still don’t understand some aspect of the manual transmission, so I should do some research.

[@juzoli]

Engineering Explained Could you go into the details how the synchronizer works? It was kindof skipped...

[@jogmas12]

Engineering Explained does it matter if the transmission is mounted to a traverse mounted engine?

What a fun time Jason! I hope yall enjoyed this video. Now I have to get this old girl put back together. :P

US Auto garage's video from 1936....watch it

[@Kirschengulasch]

This was the last piece of the puzzle for me to understand how transmissions work. I already knew the components and basic procedure, but could never actually imagine how the gears interact. Great video.

[@Roadrage-oq5js]

Right??? Me too.

[@scarygamer1778]

Same

[@kevinyouyube]

That's what I'd call "manual transmission". You're literally using your hands to shift gears 😂

[@sefyboy7183]

Yeah, Dunno about you but I literally use my hands to shift gears.

[@bass2762]

@@sefyboy7183 same bro, i always have to reach my hand into the gear box the change the gears while stepping on the clutch or i just hold the clutch with my own hand while shifting gears

[@nlsdrf1290]

Not transmitting anything though

[@zenaxia8063]

Im so glad you arent my dad

[@pilotavery]

Oh I don't use my hands directly, I shift them using a metal rod on a fulcrum to kind of poke around in there remotely with a lever. It's inside the car so that I can manipulate it to change my gears.

[@VAspeed3]

Been driving manual transmissions since the 70's, toe/heeling for over 10 years, know the names of all the components, but have never seen them in action. This consolidated all that knowledge into a functioning concept for me in 11 minutes. Everyone who drives a manual transmission vehicle should watch this and understand.

[@jonathanmatthews4774]

Been driving standard for as long as I have driven. I've never seen the actual "workings". This was absolutely fantastic in every way. More of this please.

[@DrB1900]

Yes, that was awesome. Funny though, it didn't look anything like the whiteboard drawing ;)

[@ArgueWithTheMajority]

Straight cut gears in reverse... so that's why cars in reverse sound like tiny toy rally cars...

[@TheBigDanois]

Weeeeeeeeeeeeee

[@thatoneotherotherguy]

In ten years of manual ownership I've known about straight-cut gear whine, and whine in reverse... but had never linked the two! Haha

[@fidelcatsro6948]

hahaha makes sense!

[@thatoneotherotherguy]

@Sandy Lee, hell, a number of manual trans vehicles over the years have had a synchronized reverse gear for some reason. And every manual Saab I have been in required me to park in reverse to take out the key... sometimes the auto industry is weird!

[@apexseal2811]

Just commented that without even reading yours! Haha. Seems many of us were questioning that.

[@zachariegagnon3333]

Would have been awesome to see the synchros explained

[@EngineeringExplained]

Yeah, I think that's a great topic!

[@dirtrider88]

in addition, explaining double clutching would be great too.

[@haidarao3634]

[@mattiloponen92]

I knew this stuff already but i still enjoyed this demosttation as it was very easy to understand and im sure that many ppl will learn from this.

[@darreno1450]

Excellent video. Shows the simplicity as well as the genius of the manual and why they tend to be much less problematic. You should do one on a modern automatic if you haven't done so already. As much as I can't stand automatics, the engineering is a marvel and the complexity off scale.

[@Royalfox7]

Very educational, simple, and illustrative! Thank you for this video! But there's something missing that I've always been wanting to understand, and so hopefully you'll cover it in a follow-up video as other's have requested: How do the synchromeshes work (maybe with a tie-in with rev-matching / double-clutching)? And maybe in another video: How do dual-clutch transmissions work? And maybe yet in another video: How do modern automatic transmissions shift gears smoothly without jolting the car between shifts? Hope that's not asking for too much. Thank you for your educationally addicting videos!

[@matthewfain3289]

Everything you guys explained was great! I never understood how it all actually worked. The only thing I’d love to still understand better is how the stick in the cab of the car actually changes gears when you shift. If you have any video’s on that, I’d love to see them!

Should be taught in driver's ed. Excellent articulation of transmission mechanics. Visuals set EE on a different level.
