Sequential Transmission make your car faster by improving acceleration. As with most things that make your car faster, they are more difficult to use on daily basis. Sequential shifters differ from standard manual transmissions in four main aspects: Shift patterns, gear type, gear ratios, and engagement type. Follow along with Bart in this week’s episode of Science Garage as he explains everything from dog boxes with straight cut gears, to tiptronic transmissions with synchromesh.
Bart teaches us how cars work by blowing stuff up and cutting things in half. It’s a science show for the car lover who’s easily bored. Join Bart as he explains the science behind everything automotive. This is cars down to the atom. This is Science Garage.

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

[@casey360360]

Tommy K compression braking. Well that was easy

[@NoelAWinslow]

The tendency of the wheels when moving to want to move the engine at a higher speed versus the engine being at closed throttle resisting that increase in speed. Pretty simple concept.

[@jonesy_grows]

You mean how jake brakes work?

[@anthanybowden]

Engine breaking is just closed valves on the exhaust stroke

[@NoelAWinslow]

@@anthanybowden not so much. Only valve that closes is the butterfly valve in the throttle, cam valves function normally. Since there's an air restriction in the intake, during intake stroke virtually no air enters the cylinder, and generally there's also spark/fuel cut so the spark plugs and injectors leave the cylinder dry during compression and power stroke. During the exhaust stroke it still pushes out the the tiny amount of air, but nothing burned. No power is made, so you're really just fighting the inertia of the unpowered engine, and the air pressure caused by closed throttle.

[@lobuxracer]

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.

[@johnmoore1495]

No it can be hard to follow at the pace he goes at. He never stops to really explain something in detail/slowly.

[@CZ350tuner]

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.

[@JohnKickboxing]

Hey, anyone here can tell me the reason no car manufacturer opts for this type of gearbox and integrates it with engine like the bike engine. so that the structure of engine suppresses the noise made by the dog gears.
