Default Double clutching

I'll admit I taught myself for the most part how to drive a standard, and have also learned a lot of things on the way here and there. I've recently been reading up on double clutching and been practicing it when I down shift and had a quick question...the procedure I was taught was you put the clutch in, put it in nuetral and let the clutch out, then put the clutch in, bleep the accelerator to match rpm's and it slides into gear without the car jerking...got that down but just wondering if it's completely necessary to put the clutch in twice. Can't you just bleep the accelerator while the clutch is already down the first time? Does anybody else make a habit of this also or is it not necessary since transmissions are a lot stronger then they use to be?

my dad tried teaching me to double clutch when shifting at low RPM's in my ecipse due to the fact that he was into muscle cars, so was I, and they don't have syncros so u have to double clutch... ALright, on anything like..'90+ have syncros, u dont' have to double clutch, up or down, you can do it exactly how u want to do it..

just clutch + shift, rev it up to match RPM's, let the clutch out, do NOT have to double clutch on a civic, I wouldn't recommend it unless ur driving a tractor trailer and are under a heavy load OR ur driving an older car that you have to double clutch, ur '94 civic CX has syncros in every gear except reverse, so u can downshift just fine w/o double clutching...

It sounds like ur really new to driving standard so I'ma give u one more tip... Reverse doesn't have syncros, so I'm sure more than once u've put it in reverse at a stand stilll and it crunched when you put it in, this is because the input shaft is spinning too fast, the answer to this is to hold the clutch in, put it in 4th for a second (don't take ur foot off the clutch), then shift into reverse, and let the clutch out, putting it in 4th for a second will slow the shaft down and it'll go into reverse error free...

I PERSONALY ... JUST PUSH THE CLUTCH IN AS IM RACING AND SHIFT AS FAST AS I CAN AND I DONT HAVE ANY JERKING PROBLEMS. YOU JUST HAVE TO DO IT FAST. I DONT HAVE A TAC SO I PLAY IT BY EAR AND IT WORKS FOR ME. I HAVE NEVER HEARD OF DOING IT THE WAY YOU JUST EXPLAINED. THAT JUST SOUNDS LIKE IT WOULD TAKE TO LONG TO SHIFT.

^^^ CAPS LOCK!!!!!!!^^^^^^ Turn it off. And he is talking about downshifting, not up shifting.

Good tip.

To answer your question plain and simple, you can do that whole process with just one clutch movement. Clutch in, blip the throttle, clutch out.

I wouldn't make it a habbit unless you are on the freeway and want to downshift to pass. It saves the clutch from wearing out faster but also wastes gas. There was a time when I made this a habbit coming to a stop, passing on the freeway, going into a turn. I then realized I was wasting gas and with prices these days, that's not a good idea.

Ahh okay thanks a lot. Yeah I didn't know about that in reverse, I haven't yet grinded any gears on the civic but I remember driving my friends wrx and it grinded in reverse at a stand still *whoops* so I will definetely use that.
This is my third standard so I'm not completely new I know what I'm doing for the most part, just taught myself though. I remember on my first car though I rode the clutch a lot to make it a lot "smoother" when I shifted which I learned was a no no. A lot of the things I did wrong I'm glad I did it on my first car, just learned as I went on. Just sucks when you teach yourself because if you get in bad habits you have no one to correct you

Too bad what you are doing is a complete waste of time. Turn off F&F and move on with life. DC'ing was used back in the day (prior to the 20's) for vehicles with an unsynchronized manual transmission. Since your honda was built after the 1920's, your double cluthing is doing nothing.

Actually double clutching has been covered numerous times on honda-tech and even though it was developed for older cars, I was told by numerous people it is still beneficial for the health of your synchros rather going from fifth to third and having the life of your tranny be shortened, not to mention when you down shift a lot of people riding with you don't appreciate it when the car jerks every gear, it was a simple question of whether I was doing it right and if it was completely necessary. So your analogy of F&F might be what you see in your mind but I have put my time, sweat, and blood into building my motor from the ground up and will continue to research and ask questions regardless of what you think and relate to in movies. We all weren't born with the answers unlike you my friend.

I also agree with G2 speed I can DC without anyone even noticing, is all they hear is a blip in the rpm's, it takes literally a second, and that's with me pushing in the clutch twice, but thanks for all the constructive info from everyone else, it's all I needed to know

Ladies and gentlemen this is a PRIME example of somebody who has NO idea what they're talking about.... I'll help ya out here buddy...muscle cars in the 60's and 70's didn't have syncros...it is true that the first synchromesh transmission was in 1929 on a cadi, syncros didn't really become popular nor standard at all on vehicles until the late 70's - mid to late 80's..

Also, double clutching is still required on most riggs...usually due to the load

IF ur talking about downshifting it must be a really jerky ride with you and lots of clutches....

The OP is speaking of downshifting, not upshifting

Downshifting's just as easy as upshifting, I mean it was for me when I learned I actually learned how to downshift before I upshifting..and I"m not saying I'm better or anything, it's just different technique..but again I taught myself so :-\ My dad helped me here and there but I learned by moving my eclipse around in my driveway and once or twice up the road before I got my license and then after that I drove it and everything was alright...the driveway thing really helped me with starts and moving and I'd recommend it to anybody who wants to learn how to drive standard...because starting is usually teh most common problem for people just learning how to drive standard, after that shifting is easy :-\

keep it up, you can't beat a perfect rev match, that nice blip of the throttle and slowing down without a jerk

double clutching is for trannys without synchros so you don't grind the gears, im sure you heard of donig this on fast and furios or something, ******* waste of time on any car produced past like 1988 or so....just do it the real way and powershift! I raped my friends GTI he needed a new tranny and clutch in just one week of powershifting thru 3rd gear haha

This is what I have been doing since 16 years old. And i dont understand why so many people still grind in their reverse in these days.

If that was true, why does the Lamborghini Gallardo with the e-gear transmission blip the throttle on downshits? Or the 2006 350z with the auto tranny? Or countless other cars with "tiptronic" transmissions?
It isn't a waste of time if you are smoothing out the ride.

Do you even read the majority of the post or just post your own opinion? Not to mention in F&F when he says that, they are racing from a straight line, correct me if I'm wrong but when you're racing from a dead stop you have absolutely no need to double clutch since you are shifting upwards through your gears. No matter, however hard you try when you down shift you can't shift smoothly unless you ride the clutch, and I'm sure that's much healthier You must have a stock clutch anyways if you're making comments like that, powershifting and blowing trannies...sweet.

btw if you ever watch a video of Japanese racers with the cameras in the cockpit every single one of them double clutch and rev match on their 1990+ vehicles.

To quote, click reply on the person you want to quote, on the next screen (the reply screen) quote is above the box that you type your reply in.

For your questions about the transmission are you talking about an auto tranny? Because you said something about park, because the method is for manual transmissions.
If you are talking about a manual then a little crunch is probaly normal (but "little" is subjective), if you are talking about an auto tranny then I am not sure.

ok im probbly going to catch **** for this but all the poeple i know have taught me that double clutching is when your racing and you push in the clutch at medium rpms without leting off of the gas and let it out quickly what is that called.
