very fast shift from 1st to 2nd...

[RaskyR1]

So I've notice this more than a few times and was wondering if anyone else has had this problem. When I take off fast in first and shift very fast into second it's kind of like it clunks into gear. working at a detail shop for 17 years I've driven many many cars and can't recall having this problem. If I slow it down a little it goes in fine and I get a nice chirp out of 2nd. Is there such a thing as shifting to fast??? am I just maybe not getting the clutch all the way in before I hit 2nd? I've tried really focusing on my timing and I think I'm dead on...like I said I've been driving sticks since I was 14.

anyone?

you're shifting too fast. it's bad for your tranny, and your syncros. slow it down a tad.

[tcel127]

yea i've talked to a lot of si owners about this. it has be happening to me since i started pushing the car hard, like around 1200miles, and im at 13000 miles now and it still occasionally happens. All transmissions have their little quirks. your not doing anything wrong. the tranny simply has a fault. even a company as great as honda isnt perfect. try bringing it up to your dealer and see if they have a remedy. and just be glad you dont have a real shitty transmission like in an SRT4 which i can tell you from experience requires some serious muscle just to engage 2nd everytime

[Jrfish007]

Yup, as someone said above, you are not giving the syncros enough time to do there job. Eventually they will go bad, it is a common Honda problem, I think all my manuals had problems, specially on the 2-3 shift.

Yah, shift from 1 to 2 is not smooth for me either. I guess its just the honda transmissions. If i shift too fast I also hear a click/clunk sound.

i ve never had these kind of problems, but a guy in the next town over ( only other guy with an Si in about an 80 mi radius ) had to take his to the shop because it bit so hard on slicks at the track that it broke a motor mount....

[RaskyR1]

Thanks all! Makes me feel a little better....so if I slow it down does that make me a granny shifter?!? :rolleyes:

Is that when you shift from like 1st to 3rd? I hear that term all the time and was not sure what it actually meant?

[BLU BY U]

i was just joking, kind of.

double clutching can be done going from any gear. however, i only doubleclutch when down shifting.

kinda hard to explain but basically......as an example....you are going from 1s to 2nd gear so you press the clutch in.......let it out when you in the neutral position....then push it back in.......shift into 2nd......and let it back out.

you have to do it quickly of course. helps big time when you rev match and double clutch to downshift.

here you go....

Double-clutching is usually reserved for those driving trucks or high performance racing cars, but anyone with a manual transmission can perform this simple feat.

For most manual transmission drivers, the act of shifting gears is a straightforward one. First the clutch is depressed, then the shifter is thrown into the next gear, and finally the clutch is released putting the car back into gear. All of this is usually done without thinking, at least after some practice.

But double clutching adds a third step into the mix. The shifter, rather than going straight to the next gear, makes a stop in neutral and then the clutch is released. This is to allow the engine to slow down (or with a tap on the gas, speed up when downshifting) so the transition into the next gear is much more smooth. The driver then depresses the clutch again and completes the shift into the target gear, and finally the clutch is released again, putting the car back into gear. It only takes a split second for the engine speed to match the speed of the gears, so the entire action is done very quickly as a fluid sequence of events.

Most modern cars, however, are equipped with devices called synchronizers that help to synchronize the speed of the gearbox with that of the engine. This effectively eliminates the need for double clutching. Some large trucks on the other hand have so many gears that synchronizers are inefficient, while race cars can squeeze out more power without them, making double clutching a fact of life.

There are times, however, that a normal car driver may want to make use of double clutching. Many manual transmission drivers realize the advantages of downshifting in slippery conditions. Rather than brake and skid, a car with a manual transmission can make use of the engine to slow down - thereby eliminating the possibility of a skid. But even with synchronizers, a driver trying to shift from fifth gear into second could have some trouble. In this case, double clutching by pausing in neutral and giving the engine a little gas to match speeds of the engine and gearbox, can allow such a drastic shift.

Some driving purists maintain that it's still the proper way to shift, and makes for a much smoother ride. It eliminates some of the jumpiness sometimes felt in a manual transmission car, and it decreases the stress on the gearbox. In any case, double clutching a skill worth having in emergency downshift situations, and not very difficult to learn

Thanks Blu! Wow, Samsonite, I was way off! hahaha!

[radiocontrolhead]

what i dont understand is, why must you put the cluch in adn out twice, why can't you just do it once? and wait? waht difference woudl it make to put the clutch in, shift to neutral, let it out, and put the clutch back in?

can't you just put the clutch it, shift to neutral, wait, shift to next gear and release clutch? am i not seeing something?

When i downshift, i never double clutch, i just hold teh clutch in, and rev match, and release. is there a problem w/ that? i dont see how the added work by pressing the clutch an extra time does anything

[fa1]

By holding the clutch in you'll wear out your throwout bearing faster.

[DSMKLR]

or you could just shift without letting of the throttle at all.... but i only rcomend this if you are fast...

my si is having the same problem too about to bring it to the shop monday or tuesday. i hope they fix it cuz i grinded my gears twice already and sometimes it wont even go into second gear.

[Civiconian]

YES! 1st to 2nd is the most awkward unpredictable shift I have experienced on any MT civic or other car. I have a coupe (non si) and shifting into second is like falling off a tall building and never landing (splat) in the exact same place twice. I shift, release clutch slooowww and 'sometimes' it kicks, lags or overrevs once in 2nd, so I try releasing the clutch rapidly it does the same thing! Ok, first thought comes to mind maybe cause I just got new shoes eh? WRONG, when I drive my wify's MT integra (w/ sandals on) it responds like a swiss watch, she also noticed it and she actually brought this to me attention a couple of weeks ago. We both have been driving manuals for over 14 years and never experienced this unpredictable shifting into second with any of our hondas. I'm will be going to honda tomorrow to consult w/ a technician.

How Manual Transmissions Work - Im sure you can read this and figgure it out.

Cliff's Notes: Releasing the clutch, with the gear selector in the neutral position, allows you to match the speed of the transmission to the speed the engine will be in the new gear. Think of it as rev-matching your tranny, as well as your engine. Now a days its mostly moot, due to synchros.

In Rasky1's case, hes shifting too fast for the synchros to take effect, so double clutching would help in 2 ways, first it woudl match the speed of the gearbox so the synchros woudlnt have to do as much (if anything) and it would also slow him down, letting the synchros have enough time to work.

i feel the same way about my car, it does the same thing

i have found that it is best to just let the clutch out slowly when going from 1st to 2nd, but it does suck a lot that you cant drive this car fast, shifting from 1st to 2nd


i feel like it is because of the rev hang, b/c if i shift slower it doesnt jerk, or bog, or anything, but too slow and its worse

only happens from 1-2 though...


i'm just hoping when hondata does come out with a R18 reflash, that they will address the revhang, the 1-2 shift, and the bog from about 1000-2000rpm while taking off in 1st

[NeverNZ]

also, this has NOTHING to do with needing to double clutch, double clutching is useless in modern transmissions
