There was a video on youtube of a guy shifting without engaging his clutch. he said that it was easier on the synchros and such.

http://www.youtube.com/watch?v=0AJXsVj-PMg Theres the video.

He said that he had discussed it on a forum. Really im just wondering is this better for your tranny? or Worse? And how to do it?

 

i don't know if it would be worth driving like that all day long. maybe it was just me but the one time i did try it didn't seem too smooth. maybe i was doing it wrong though.

 

WTF is he doing just shoving it in gear?

 

I think thats the basic idea, im not sure if theres a trick to it or what not. Im really just curious because he said it was easier on the synchromesh?

 

a few times in the vid it sounded like he grinded.
but the shifting isnt too smooth.
my friend was doing it the other day
it jerks everytime you go into the next gear.

i think what you have to do is pull it out of gear when the engine is at the most neutral state when running. i dont know how to explain this really, but kinda like when u give it gas and u let off a little bit and you can feel when the engine doesnt have any stress. like the point between accelerating and engine braking. cuz i noticed when my motor is at that point, i can pull the shifter out of gear without pressing the clutch and its real smooth, but i never tried going into the next gear. our trannys are bad enough and doing that would/could make it worse

 

don't do on the downshift. i know from my experience you don't shift under 3-3,500rpm and don't rev to the sky either. it's pretty simple first you start like you normally do w/the clutch let's say you hit 4k let go of the gas shift then place your foot back on the gas. or thats how i was taught... he if i'm wrong, my bad...

 

I would not even try that in my MS3 cuz my tranny would Explode. +1 for Honda Transmissions!!!!

 

thats another thing im tryin to figure out. the guy on the vid says its better for your synchro mesh cuz it puts less stress on it. is there anyone who honestly knows about trannys to answer this question?

 

Clutchless shifting is exactly what it sounds like, shifting without the clutch. It's possible, but I wouldnt recommend it because there is a greater chance of grinding your synchros.

It's all basically REV MATCHING. Basically when the engine is revving down, there is a point where the engine and the transmission are spinning at the same time. At that moment, you are able to shift out of gear and into neutral. Then just below that moment will be the speed at which is the engine is spinning for the NEXT gear. At that moment, you should be able to shift it into the next gear smoothly.

For example: for THEORETICAL SAKE (NOT ACTUAL NUMBERS)
Imagine revving up to 5000rpms, when you step off the gas, the revs will drop. Once your engine reaches 3000rpms, that is the speed at which the engine and the tranny are spinning at the same time. Therefore you can shift to neutral. Then your revs will drop some more. Lets say for example, your next gear is at 2500rpm, that is the exact moment your engine will engage at if you shifted up to the next gear. At that moment, you should be able to shift up to the next gear.

so... rev up to 5000......step off....3000 shift to neutral....2500 put into next gear....

something like that.

AGAIN THAT WAS FOR THEORETICAL SAKE, NOT ACTUAL NUMBERS.

Yes it's possible, but for it to be BETTER for the synchros? I highly doubt it. I mean, if you are able to pull it off DEAD ON EVERY SINGLE TIME, it would be better for the tranny. But most likely you're not, therefore you will grind your gears every time you miss. Otherwise, the only other time this method would be helpful is if your clutch doesnt work any more and you've got to limp home somehow, ha.

But yeah, you can play around with it abit. Next time you drive, when you pull up to a red light, step off the gas. As you are slowing down, put slight pressure on your shifter and it will eventually pop out of place into neutral.

But if you REALLY want to try it out. Rev up to 3500rpms, on 1st gear, then pull down....eventually it will pop out of place...keep pulling...and it will eventually pop (or grind) into 2nd gear. Then for the next gear, drive up to 3500rpms, the push up... eventually it will pop out of place... keep pushing...and it will eventually pop (or grind) into 3rd gear. etc. If it pops into place, you did it right. If you GRIND, you didnt do it fast enough.

 

basically its not for hard driving. i do it when im lazy and cruising around town. basically every gear has a point where the synchros line up well enough to put in gear with out engaging the clutch itself.

rull of thumb. the correct rpm range for everything to line up right to do this is 3500-4000k rpms. i dont recommend this as a dialy mode of shifting. but it can be done.

ex: in 1st gear drive till 4k rpms or so. (enough room for a person to figure out the engagement point). when you reach above the desired rpm you pull the shifter to neutral(let off throttle) and as the rpms are dropping you can pull back on the shifter from neutral to the next gear and it slips into gear without grinding(2nd gear all the way to 5th). if you miss the right rpm point it does not pull into gear. typically for every gear the desired rpm range is between 3500-4000. if you are driving normal and not high in rpm you downshift the same way.

down shift ex:
4th into 3rd at cruising speed. as your driving in 4th at or around 4k rpms you can pull the shifter into nuetral or rev the motor till it is with in the desired rpm range 4k rpm (you have to find it on your car but 4k is the what i have noticed is the safe rpms to start the process.) and push shifter into 3rd as rpms drop and it slides into third. same for second gear but i dont recommend that.

hope that helps. since i didnt watch the video im assuming he was trying to do this normal. bever seen it done racing on the street or track.

 

i do it all the time as well.. i can even come to almost a complete stop while putting my car in first gear.. basically the way i explain it is exactly what you guys are saying... just shift w.o. touching the clutch and as long as you are above the needed rpm while the engine is winding down it will find the sweet spot and fall into gear.. as long as you have pressure on the shifter into the desired gear... down shifting is the same

i was told that it is better for the tranny in that it puts less stress on the tranny components but idk about all of that..

i just do it b.c its easier..

 

Your willing to risk all that money just cause its easier. I dont care what anyone says because the car has a clutch for a reason.

800$ to pull tranny.... Check

Another 3 to 800 for the work/parts... check

****ing up your tranny cuz its easier to Shove it into gear..... Priceless

Granted its your car and I dont really care but I find this hilarious.

 

x2. it's soooo hard to push the clutch in while shifting. this is why honda is reluctant to fix trannies under warranty; people are abusing them for no reason at all.

 

i think that honda is more hesitant to fix trannys because of the green NOT because a few people can shift without the clutch.

 

not just shifting without the clutch, just abusing them in general. why should honda pay for peoples' ****ups?

 

Exxxxaktly, theres dumb *** people out there spreading dumb information and idiots following that information. Theres the idiots who rev the car past redline and say it wont do anything. Theres the idoiots who purposely dont use the clutch because someone made a 1 min vid on youtube showing you how to do it.

And yet we all wonder why Honda gives **** when you say "transmission".

 

lol @ doing it because it's easier.
pushing in a clutch isn't hard you know.... :shrugs:

 

Just remove the clutch pedal while your at.
You wouldn't need it.
You'll be on the fast track to replacing your tranny by doing that.

 

im not guna try it because i dont wana hurt my tranny but if you dont have proof one way or another i dont think you can call anyone an idiot. no one has really answered the question who knows. arent there some techs or mechs on these forums somewhere?

 

I would advise you not to do it at all.
The clutch serves a purpose.
Its not just there for preference.

This thread is pointless.

 

oh really? you make it sound so simple like u just give it gas then throw in the next gear

 

It is very simple, with lots of practice and you know what you're doing of course.

 

Its either a hit or fail, you get it right well then good for you, you miss and your timing is off you will slowly grind the gear and if you really suck and totally jam it into gear and did it really bad and you hear your tranny starts to grind and then you hear a big clunk, its time for a new tranny.

Lots of people on semi trucks shifts without using the clutch.
Basically another way to kind of see the picture is to image two flywheel back to back with a slot turning at different speeds and your waiting for the perfect timing when the two slots line up so you can shift into to.
You can pop out of gears easily, its putting it into gear that gets a bit more tricky.

just drive normally with your foot on the gas, cruse around 3k rpm at which ever speeds you like, apply and hold little pressure on your shift *** towards neutral and let go of gas and remove pressure on shift *** after it pops out of gear and into neutral and ta da...you just poped it out of gear

 

all he's doing is easing it out of gear, and to down shift all you have to do is rev-match the rpm to the gear.

not really beneficial to do, unless you have a clutch that is going out. it does save wear and tear on your clutch, but it's not how you should be driving around day to day.

 

i can do both up shifting and down shifting... pretty much only need to push the clutch in first gear...

its something that does take practice to do and i dont feel that it hurts anything (taking into account you do it right)...

one time i did it without even thinking any my friend was like "WTF"..? hahha
