Those were actually only built in manual and that's a good thing because the auto trans was a ticking time bomb and the "manual" mode is one of few where you can confidently say you would be faster shifting yourself

1:52 "The need for a clutch is eliminated [...]" You're leaving out quite a chunk here. Should be either "The need for a clutch is eliminated if you have a quickshifter" or "The need for a clutch is eliminated if you know what you're doing, and even then this can put quite some wear on the poor thing if your timing isnt right". To change a gear, a sequential transmission has to be free of load. Modern cars and many bikes will cut the ignition for a split second which accomplishes that. If not, you have to invert the throttle for a gear change. So if you accelerate and want to shift up, you have to put mild pressure on the gear lever, then close the throttle and open it again very quickly. Or vice versa, for a downshift, give it some throttle for a brief moment. The gear will change "itself" the moment when load is around zero. In this scenario there are soooooo many ways to fuck up. I managed to: - not close the throttle far enough, making me land between gears - not go through the gear change all the way, making me land between gears - not close the throttle far enough, but apply a lot of pressure on the gear lever, which does the gear change, but is audibly BAD for the transmission - do the gear change before I want it, because I go over a hump Not saying, you shouldnt shift clutchless (I do it all the time). Just that your info is too casual.

[@assi2assi]

yes or (especially on a bike)tip the fking clutch.if you do it right it takes not long and you dont have to worry about fking sth up sure if you race and rev the shit out of it you dont clutch,but then you dont give a shit about wear xD

[@brettershoalar9001]

Ignition timing and seq gearboxes? I know that most of the time you install the box together with a 'ignition cut system'. Yes, this needs to be set up propa anyway.

[@brettershoalar9001]

Nate Diggaroo yeah, I've heard stories about loose selector forks or bad runout on the selector shaft. Normally you should not be on the throttle during shift IF you're not working with a ignition time breaker during shifts.

I actually love the whine of the sequential transmission in my e46 m3, and it’s not a pain in the ass for driving around city, I think mostly because the car will downshift for you, and it has automatic mode which is a nice feature. I mostly drive it in regular mode and don’t often use the paddle shifters, I feel that you get a better and faster response when shifting from the knob.

[@michaeldavis2531]

They don't necessarily always need to be hydraulic or pneumatic actuators. In this case of a sequential transmission with a manual shift lever, it's usually just a mechanical linkage.

[@vitark1544]

I recently drove a racecar with a 6 speed dog box and I say that it's the most awesome and connected feeling you get with a car! You feel everything on the gearbox and I didn't do clutchless shifts although I saw the owner do it and was amazed by the low drop in RPM and shift time.

[@8PK4Life8]

FYI: The reason you don't need a clutch on some sequential upshifts is only down to electronics, i.e ignition/fuel cut (or closing the throttle slightly), and a blipping system on the downshifts. I use the clutch on my bike engined car for downshifts and for 1st to 2nd as you have to cross neutral.

[@futureshit-glungis7202]

You can do a clutchless upshift without an electronic quickshifter if you let off the gas and get the timing right. And theoretically you could also blipp it down but this is far far more difficult and i dont think a human could really do that reliably enough to mot hurt the transmission

[@Ninja98x]

Just wanted to point out one small inaccuracy: straight-cut gears don't actually have less power loss than helical gears. Both have pretty much negligible power loss, but helical gears are actually just a tiny tiny bit more efficient. However, the reason racecars use straight-cut gears is because helical gears introduce forces in extra directions. Basically they want to push past each other and they want to push each other apart. These extra forces mean the gearbox housing needs to be stronger, which makes it heavier. So the TL;DR is: straight-cut gears are not more efficient, but they allow a lighter transmission housing, so the car can be just a little bit lighter.

Sequential gearboxes are goals for speed! That's why I don't understand the manual elitist that talk down about semi-autos or dual clutch transmissions because these days they are getting close to speed with sequential and shift faster than the average manual driver.

[@Wildchildinc]

There's still a delay downshifting even with heel + toe. I'm just saying there is no point for elitist to be down talking semi-autos/dual clutch when they are getting to speed with sequential transmissions. In the end, driving a manual isn't all too impressive because it becomes second nature with practice like learning an instrument. No matter what car or transmission a user enjoys, spirited driving will always be fun.

[@hyperlogos]

If all you care about is the best driving experience then you should have a modern automatic, they make shifts faster than you do and since they have a torque converter power stays smooth while shifting.

[@rickyduran7673]

Thx for translating to u.s currency

[@rajgill7576]

The straight cut gears are not just a clunky and noisy hassle, the whole point of helical cut conventional gears is that they have a higher engagement area and wear less when being engaged in and out of shifts. Str8 cut will wear quicker, but hopefully past the life of the vehicle.

[@FamousAndYouKnowIt]

You can skip gears in a sequential box... like from second to fourth... just clutch in, blip the shifter twice and let the clutch out.

[@ueehurstonsecurity8887]

thats not skipping gears, as far as the gear box goes. your still hitting all the gears its just not engaging the power to the wheels by skipping gears it would mean legit skipping them in the transmission, from 6 to 3 in one shift, one movement

[@Chimera6297]

I like my H pattern, I would probably love a sequential but I can chirp the tires pretty consistently on an upshift which is very satisfying sometimes. and I feel like I shift fast enough. I've driven a DCT and it sure is fun to just put your foot to the floor and go through the gears, but it's electronically controlled. something is missing from the equation. I suppose the traditional sequential is more mechanical so that would be pretty cool. maybe I just like slamming gears and hitting that perfect heel-toe downshift, who knows lol and for those of you wondering, you actually CAN convert your H pattern to a sequential shift pattern by installing a sequential shifter. You'd still have to use the clutch shift but it's a basic "back to go up, forward to go down". probably not as quick, but it IS cheaper than shelling out metric f*cktons of money for a transmission that is going to be driven hard AF

[@S1Sequential]

Can I correct this, a sequential gearbox doesn’t have to be clutchless what this guy is describing is a sequential dog box. Drivers often clutch even sequential dog boxes on down shifts to smooth the shift this is sometimes on upshifts too, this is especially the case with larger road car engines that have high rotating mass. Also, although a selector drum shaft is a common way to select the gears it is not a requirement of a sequential gearbox any mechanical/electronic method can be used. A sequential gearbox is simply a gearbox in which gears are selected sequential (in order, one after the other )

[@Dirk_Taggesell]

Was wondering the same. Either the clutch IS involved during shift (for the fraction of a second), or the electronics that controls the shifting dials back the engine torque just enough to switch gears flawlessly - rev-matching as well. I think this might be different from car to car. BTW: my smart definitely disengages the clutch while shifting :) (yes, that has a sequential gearbox too)

[@realENGY]

You don't have to use the clutch, but then you have to match the RPMs of the gear you are going to engage. This can either be done electronically or manually with the throttle.

[@TheCrazyBird844]

Johnny Pea Mororcycle sequentials don't have to be built to withstand torque like the ones for cars do I'd imagine. Weaker materials can be used which equals less cost, and they're also making an ass load of them all the exact same which drives the price down. Getting one made for your car would be a lot more expensive. The example he gave is specifically made for the Miata and to handle over 300 lb/ft of torque, they probably don't make very many a year which makes it expensive and it's build to withstand quite a bit more torque than a stock Miata.

[@flyzx2]

There is (ideally) no sliding motion, and therefore, frictional losses, between tooth surfaces of gears due to the profile of the teeth. The advantage of spur gears in racing applications is the lack of trust loads (along the axis of rotation of the gear) which would be induced by helical gears. This allows for a lighter gearbox assembly.

[@BigSpaghetti6]

Straight cut gears are not prefered because of reduced friction, it is because of the weightsavings you get from the transmission

[@TheWoebegoneJackal]

I feel that the last point made is exactly why I enjoy H pattern manuals. I mean, of course sequentials and dual-clutches are faster overall, but driving a traditional manual just feels so good.

The reason you can change gear without a clutch has nothing to do with it being sequential. Its because the gearbox uses dog engagement instead of synchros. I drove a car many years that was standard H pattern with dog engagement which was nice. Also note that that standard dog boxes require the clutch for downshifts. This can be overcome with electronics to auto blip the throttle on downshifts - most new top end motorcycles have this fitted due to throttle by wire.

[@easyenetwork2023]

NASCAR still has dog boxes at the Xfinity level and below.
