Dog Boxes & Sequential Transmission | How it Works 

God I miss these. They were so informative and so, so weird

Once again I understood 6% of the words, but was 100% entertained.

"If I need to shift really fast, I take fiber supplements" lmaooooo

Where’s Bart at now? He was one of my favourite hosts

Going back to rewatch Science Garage after finishing a mechanical physics class makes it even cooler. I get why Bart had to leave but I miss him :(

Up and down are the only options, like in an elevator, or self medicating

"Granny Shifting... Not double clutchin' like you should.." 😎 lmao

We need bart back!!! There are so many things left out

This guy is so excited to talk about absolutely anything. I love it😂

4:13 RIP Hammy the hamster.

This is complicated.

up or down like *self medicating*

You guys could have used a boxer for the boxing dog poster but instead you went with a pug and that’s why I love you guys

3:26 Best Part 😂😂

Good days when donut media used to drop good videos

You must be a real piece of work to shift from 5th to 2nd..

For the next science garage, you should talk about engine braking, and what it is. Since you just talked about diesel.

Music was a bit loud for this one :(

Double Dammit!!! I have got to say, when I am either feeling a little down or just plain overwhelmed by the ridiculousness of the world. I pull up one of Vince's videos and by Zeus I feel great. Thanks for the energy you put into these videos, on days like today, they are fantastic!

I miss Bart. I rewatch these for his funny antics

3:27 MY NUTS MOVED

Bmw turning lights | how it works Differential 2 | how it works Misfiring system | how it works Chassis | how it works

Being English I physically can't express how much i love these videos. Never change Bart. I love you man.

5:16 VTEC overloading

Please bring back Bart and science garage, this is literally one of your best segments, it’s a toss up between this and up to speed

The background music is too loud :/

1am, was about to go to sleep, plenty of work to do on the subaru once I wake up and then edit the vid for it... but no.. Im now grabbing a bowl of ice cream to watch Donut...

Bart , you’re my favorite. You give me smiles

Where's this dude now?

This popped up in my recommended again. I miss bart

"Shove it right into the second one" 😏😏 3:24 🤔😏🤔

3:27 Bro i lost it 🤣🤣🤣👌👌👌 perfect explanation. Keep it up donut. ScienceGarage is best show from donut, forreal.

Bart please come back, we miss you

just a turbo casually chilling on the kitchen counter

The dogs on the gear at 6:18 are so beyond hammered, I doubt that gear would actually hold lawn mower torque. I learned a lot about undercutting dogs and re-shimming factory transmissions when I worked on motorcycles for road racing years ago. Lots of painstaking grinding to get the dogs and holes with the proper engagement to pull themselves together under power instead of pushing apart, and a lot of careful adjustments to get 90% or better dog engagement in the holes. All that said, synchro boxes also have dogs, but they're super tiny compared to a "dog" box. I have a bunch of spare parts from my Getrag 233 rebuild that are really awesome for demonstrating exactly how synchronizers work and how dogs engage. That gearbox is also known as the Toyota V-160, a legendary transmission designed for 400 N m of torque, but capable of surviving 1000 ft-lbs of torque.

Next video of how it works: bmw blinker liquid

Have you guys considered covering the various types of fuel delivery? Like direct injection? Or the differences between Electronic Fuel Injection versus Sequential Fuel Injection?

Bart you were hilarious in this video. I was crying with laughter - more of this!

Bart's the best!

Not all motorcycle gearboxes use a grooved selector shaft. Some, such as Jawa & CZ, use a ratchetting selector fork guide plate, which is moved via sprung pawls, which are activated by a prong on the gear pedal shaft. On Jawa & CZ gearboxes there is also an automatic declutching mechanism (a slick shifter) when ever the gear lever pedal is lifted or depressed. Holding the gear pedal fully up or down pulls in the clutch, allowing the rider to use the gear pedal as a backup clutch control should the clutch cable break.

4:11 was hilarious 😂😂

2:35 The Emporor's new groove is so good

mans ripping these puns in half. cant stop laughing, "no walk in the dog park"

I miss this show

I was doing about 95 or so in a '64 Chevy shortwide i used to have... It had an auto on the tree with a shift kit mated to a 383 stroker.. I was talking to a friend and snagged the shifter with my hand and slammed the tranny into reverse, O.O, i thought for sure that was the end of that tranny, but all that happened was a serious white smoking of tires as they flew into reverse and back again real quick... Whoever built that trans was damn good lol...I miss that truck.

uh, yea, hi, why wasn't '"Dog Engagement" accompanied by a picture of two dogs getting married? Now I'm upset

"head home to olive garden" I'd love to live at olive garden

We would like to see some automatic transmission in next post!

"Standard gears are just like shoe boxes in my closet. Filled with baby teeth" is the line that caught me off guard 😂😂😂

I would watch if Bart made his own channel.

i miss this kind of videos so much! and him too!

I love these. Smart and hilarious. Seriously I laugh more at Science Garage's "subtle" jokes than any other youtube content.

Guys I didn’t really understand... you lost me at the minute where you show how the gear shifts

Always laughing my ribs off watching Bart

Being honest... Science Garage is way better than rest of the shows. I want to know more about mechanisms of those components than Cars... I want you to continue this forever..

Man I miss this guy so much

Bro you are such a spazz 😂 Made this learning so entertaining!

Is it just me or does everything he says go in one ear and out the other? O its just me. Ok then.

I don't understand why normal cars don't have sequential transmission, almost no one skips gears and its way easier to learn

This is without a doubt the funniest science garage yet.

Do a video on E85

What 😢 happened to these episodes…ahhh the golden age😢

5:44 gnarly jumpscare

We never got the dual clutch transmission episode 🥺

This guy is awesome! First vid I've seen of him.... bring him back!

Actually learned a whole lot...thank you AND!! I subscribed

I love the humor in this segment. Just content gold. Keep up the great videos guys. I'm definitely smarter about cars because of you guys.

Why didnt he say "over and over and over" dissapointed ...

2:06 Norwegian OORAH! Great video, might sequential swap my V70

I watched until the end of the video to say thanks for not putting ad in the start and middle of the video.

Triple H Shift Transmission oof

Thank you for the triple H joke 👍🏽

How about alignment? Can we get a how it works for camber, caster, toe, etc.

Y’all need to bring this guy back.

Bro the humor in this video are like stun grenades 😂

hey man, try lowering the volume of the bgm a little lol

We need you back my friend 😭😭😭😓

We miss you ❤️

i kinda like how he always is so excited about everything

Please bring science garage please!! 🙏🙏🙏

what happened to this guy we was a great mix to donut media

It's easy, Sequential transmission is Ken Blocks while normal(h-pattern) manual transmission is Vin Diesel😇

Kuzco going “ha” got me laughing so hard.

Dog engagement is the best engagement.... Rev matching is downright fun, and there's just enough play between dogs that someone really good can sequentially shift up or down gears without ever using the clutch without risk of damaging anything.

I shifted from 90mph into Reverse in an old Ford Aerostar van and rolled the thing three times down a hill, landing upside down in a little baby creek with a tiny dot of water trickling through. "The Incident" caused most of the windows to quit existing and the baby creek made it's way through, gently flowing over the roof, which was now a foot underneath me.. Fortunately, I just put my seatbelt on like 60 seconds prior to "The Incident". So did my passenger. When we spun, we got slammed into the doors from the G forces and we made eye contact, which I'll never forget. We spun hard about 2¾ rotations from the rear end locking up So here we are...both strapped upside down in our seats like a coupla dummies what just flipped a van. After a few seconds of mental regrouping, I look over "Holy shit...You all good bro? You still with me...what a fuckin ride" I look down at the floor shifter...which is still in R... "Don't want anyone seeing that" I chuckled, as I slipped it back into it's proper crashing position of D. After establishing that we were both alive, our next move was to get out. Mother nature didn't miss a beat, as the stream successfully navigated directly under myself. There is no easy way of undoing yourself while not falling...I dropped right on my neck and got a little wet from the tiny water, with my crash buddy following suit moments after. We squeezed out our respective side windows, which were nowhere to be seen if you're keeping score. As I emerge into the world, I am confronted by a short, but steep hill that is blocking me from getting back up to the road. We both slid down a few times which was absolutely hilarious, when suddenly we hear a stern voice call down, "You boys alright?" To which I replied "Yeah...we're good", and he disappears behind the hill. Between laughing, crashing and being quite steep, this fuckin hill is kicking my ass and it must of took a solid 90 seconds to successfully tackle it. The guy was nowhere to be seen!!! Haha...about 2 minutes later an off duty fireman showed up because he heard "The Incident" and went looking for skid marks on the state route. This all happened down in the Southern Tier of New York state outside of a teeny little town called Nunda...on the first day of school in 1993, when I skipped school, walked to her job, and stole the van for the day. Drove it 70 miles to my buddies dad's hunting cabin and had some peach wine and played with some rifles, shotguns and bows for 4 hours. We got a little squirrelly on the dirt road and buckled up...we were gonna coast down this 5 mile long hill on the state route, and we hit a pothole as I was putting it into Neutral. It went into Reverse instead...which caused "The Incident" you just read about.

Can you make a channel for bikes too.. since you already have a million now..it would be easier I believe.. Please make this happen 😍😊

Why is the auto generated caption in dutch?

All right I love donut media and everything but for a non native English talker this was pretty hard

Do they have a third pedal for the clutch?

This is information I am so happy to find, the things they hide from us in metal cases, GEARS.

I miss bart

Up to speed on the Toyota hilux please

2:05 Im also a norwegian who skipped 8th grade #schoolreform97

I’m learning and laughing! Thanks science Garage!! Love you all

The “Dog” term comes from machining We use “Dogs” and “dog legs” as a way to input force onto rotating shaft on the Lathe. Pretty much a handle but they’ve been called dogs and dog legs for years and years

"heading home to Olive Garden"

Let’s pretend that I understood everything

i love seein a 280/0 like to dislike ratio

Dog is a type of engagement, compared to synchro engagement. Straight cut gears opposed to helical cut gears. I have manual transmission with straight cut gears and regular synchro engagement ( gear whine from straight cut gears is real ) A dogbox is simply a transmission with dog engagement, but doesn’t mean there are straight cut gears.

I do miss these
