whats up people, i just learned a new trick called "shift on the fly", its a way to get in gear and out of gear without clutching. this technique is nothing new, all manual transmissions can do this.

every type of car has its own shifting point depending on the amount of RPM's needed. Our tC's shifting point is at 2,800 RPM.

its pretty neat once you get the hang of it. when your driving normally (assuming you shift at 3RPM) through 2,3,and 4 gear, just release the gas pedal and easily shift out of gear and into the next gear. its very simple, whats happening is your rpm will drop into shifting point and youll automatically shift out and into gear without grinding. since our gearbox is syncronized, you know how your gearbox refuses to get into gear when your dont press on the clutch from neutral? thats not the case, once your rpms hit at shifting point you can get into gear without being blocked and without grinding...

BUT, DO NOT shift on the fly when your pressing the gas pedal; your flywheel will go too fast for your gears to go in. also DO NOT just rev your engine to shifting point and try to shift on the fly, you will grind your gears that way. in other words, do not accelerate/rev while "shifting on the fly". also shift on the fly will not work at stopping point or 1st gear, youll just stall out.


i think everyone should try this, it so "COOL". at least once you guys, and youll be amazed! and you can impress your friends as if it was MAGIC!!!!!

 

And when you "MAGICALLY" lunch your synchros, ask yourself how "COOL" was this??????????

 

same thing as power shifting

i helped ruin a transmission that way at work it was a work truck, it broke on somebody else

 

ok, a few things. 1st off, it's hardly shift on the fly on a Scion tC..... it isnt a Honda. The engine speed just like to hang there. And usually it's still faster to shift with clutch depression.
This has also been discussed before

DO NOT try this on a tC unless you dont care about the damage and the tC is your beater car.

 

well i forgot to mention it can wear out your syncronized rings. but its so "COOL"!!!!!! "COOL"!!!! im getting a new cluch anyway... and this is something pretty neat to show off, not a routine.

I got a better discription.....
"Shifting without the clutch"
It is possible to shift gears without using the clutch at all, by careful throttle manipulation. When transmissions were unsynchronized this was usually the easiest method, and still works in modern cars, although it requires a lot more practice than the usual methods described above.

Although the technique works in synchronized gearboxes, it is inappropriate in nearly all circumstances. A synchronized gearbox has a small clutch called a synchronizer (or "synchro") in every forward gear which brings the input and output rotation to the same speed before allowing them to engage. Like the main clutch, these synchronizing clutches use friction. These synchronizing clutches will allow for a margin of error when engaging without the main clutch. If the engine speed is somewhat too high or too low, the synchro will essentially take on the job that the fully engaged main clutch isn't doing. However, a synchro ring is not intended to do the job of a main clutch. Its job is to spin up or spin down just the input part of the transmission that is assumed to be disconnected from the engine. It is not intended to speed up or slow down the entire engine. Such experimentation done on a regular basis will prematurely wear out the synchro rings, which will have to be replaced.

On cars with a freewheel, such as the older SAAB with a two-stroke engine, shifting without the clutch is standard procedure. But actually, the freewheel is a form of clutch: one that is disengaged whenever the input rotation is slower than then output rotation. One must disengage the freewheel by allowing the engine revolutions to drop, which is analogous to pressing the clutch pedal.

 

Will you be disassembleing your transmission to replace the synchro rings while you are getting this new clutch too? For those other guys out there with some sense, DON"T DO THIS! Or you will be the "COOL" guy with the broke transmission.

 

shifting without a clutch on a snychronized transmission is just asking for trouble, unless you 200% know what you're doing.

What is happening is that, sure, you can shift once you release most of the pressure by letting off the gas, but your synchros take a LOTTT of wear, because instead of getting the next gear up to speed, it has to change the speed of the entire engine.

Not good! Only practical for unsynchronized trannies, like big rigs, or someone who really, really, really knows what they are doing

 

^or bikes, i do this all the time on my bike, for faster shifting....but it doesn't hurt. I don't see how this is considered "cool"? I wouldn't do it in my tc

 

by the way, clutchless shifting is not the same as power shifting

 

Definatley not "COOL" and would make your shifts way slower anyways. This will be me being "COOL" when your tranny goes on you!

 

I think I'll just use my clutch...

 

I think i'll just sip my drink while driving....only automatics should not use a clutch.

 

Yea, but as we know as well, some slushie drivers still aren't immune to bad shifting habits

case in point, I was once in a tC with this guy (way before I became a SLer or even interested in a tC), and he had an auto... anyways, he would ALWAYS use the 1-2 when taking off at red lights! I was like

 

I'll take clutched shifting thank you. My car seems to like it when I drive like an intelligent person.

 

LOL what a wannabe

 

I remember I did this on accident. I was whipping it down the hill and some immature pedestrian(you know the ones that think theyre invincible) just decides to jump in the middle of the road.
I was in 4th and everything happened so quick I jumped from 4 to 2, than I got into neutral.

 

its ok to put the shifter into neutral without disengaging the clutch... but you should really be using your clutch pedal whenever you move the shifter

 

By an automatic if you dont wanna use the clutch!

 

If you drove a big truck ( which sometimes have 27 gears ) you would do clutchlessly too.

 

it's so COOOOOL lol... nah dude...nah... and this guy should be banned for making such a stupid post, some kid might read this and try it on his car...
