I have a question about shifting down. I use the double clutch technique to skip down a gear. So if Im in 4th gear and I want to go to second. I push the clutch once to shift to neutral, and then push in the clutch again to shift to second. I know that if you shift from 4th to second directly without double clutch (so pushing the clutch once while shifting from fourth to second) is bad for the car. But can you shift from fourth to second with the clutch in once if you shift to third gear first? So .... clutch in.....shift to third then second while the clutch is in the whole time. I heard that this is ok for the car. Is this bad for the car?

Rep Power: 0 I don't think it's bad for the car.. I never "double clutch" when shifting down. For instance when I'm on the highway towards my house and have to pull into a street I just slow down, clutch in, shift to third and give it enough gas to catch then I'm done.

Rep Power: 395 I don't know why you would double clutch? Just downshift and feather the clutch while applying some gas. That will match the rpm's and you'll be fine. You can also do heal-toe downshifting; downshift and feather the gear in using the clutch while braking and adding gas at the same time. I've gotten pretty good at doing that. It's mostly useful in turns for late braking and faster exit speeds.

Rep Power: 0 if you are talking about real double-clutching then you have to match your engine speed for the shift down. If I understand your question you are not pulling the clutch out to do so. By putting in the clutch and holding it in all you are really doing is giving your flywheel a few extra seconds to slow down. So I would say that it probably isn't good for the car unless you are going to match engine speed. If you are in fourth and shift to second regardless of third without matching the speed you already know what will happen as your head starts jerking toward your steering wheel... thats the main part you should consider.

Rep Power: 0 clutching like that wont do crap compared to a straight 4-2 shift because you are not rev matching. you might actually hurt the syncros more cause you are letting the rpms fall more so they heat up more to match 2nd gear.
what you are supposed to do when skipping a gear when down shifting is clutch in, shift, give gas to match the rpms of the gear you want to go into, clutch out.
at 40 mph (im crusin in 4th) and i for some reason need 2nd gear accel, then i engage clutch, shift while gassing to 4krpm (i think this is the # for 2nd gear at 40) then disengage clutch. then the gas pedal hits the floor.
long ago before i stopped racing on the highways, i pulled up next to a porsche 911 tt, and just for kicks we both gunned it from 60 mph. i guess he didnt downshift or something cause i was in 3rd gear at 60 mph. i pulled ahead quick but eventually got smoked.

Rep Power: 389 I shift straight from 4th to 2nd or 5th to 2nd all the time when exiting the highway. Just matching the rpms and not abusing the engine. No problems so far.

Rep Power: 559 yeah dude, you just gotta work it. every car is different, just get comfortable with the car and try different things. dont think too much about it tho, driving is supposed to be fun. just dont let the revs go into red, or youll fugk up your engine like that.

Rep Power: 0 Rev-match...easier on the clutch. On my car...say a 4-2 downshift at 40mph...I like to bring the RPMs up to around 3000rpm before engaging 2nd. Much smoother and easier on the clutch.

Rep Power: 0 I remember when I first learned to drive a manual. My brother and I were driving some POS minivan that we bought for $500.00.
I was geting off the freeway and going left. I shifted to second, and then what I thought was third at around 42mph, but ended up back in 1st. Talk about a jolt. That van was never the same after that.[IMG]i/expressions/laugh2.gif[/IMG]

Rep Power: 375 lol.... look.... someone SEARCHED! lol.
Rev matching is this...
Let's say I'm in 3rd gear in my S2000 at 4000rpm..... I want to downshift to 2nd. To rev match, I push the clutch in, downshift to 2nd, and BEFORE letting the clutch out... I bring the revs up to around 6000rpm, since at my current speed, I figure I'll be at 6000rpms in 2nd gear. Now i let the clutch out.
That's rev matching.

Rep Power: 0 i see, i was confused because what's the different between double clutch and rev matching then? I mean since you can rev up the engine just b4 you let go of the clutch, why would you want to do double clutch, which has one more step and the same effect?

Many older cars did not have any synchros, so if you wanted to downshift, you had to disengage the transmission (clutch-in), rev-match, and then reengage the transmission (clutch-out).
So you're right - with today's cars, there's no point in double-clutching.

Rep Power: 0 I understand there is no point in doing this when driving at normal speeds, but I don't understand why everyone is saying that you should never ever double-clutch or heel and toe just because we have synchros. Isn't that part of what makes driving a manual tranmission fun, and just plain better than a slushbox ever could be?
If you're going to downshift at high speed going into a turn, to heel and toe will help ensure your front tires (or whatever the drive wheels are) maintain traction. Yeah, I know that belongs on a race track, anyway.... another thing, if you are downshifting, and you know there will be a large increase in engine speed, say you will be going from something like 2000rpm to 6000rpm, matching revs is actually quicker and much smoother than straining the synchros and playin with the clutch etc. Does anyone here actually like to drive or what?[IMG]i/expressions/face-icon-small-confused.gif[/IMG]

Rep Power: 0 Ok, yeah "rev matching" is keeping the clutch disengaged in neutral, still using synchros. I meant to say doulble-clutch/heeltoe... and I know its not necessary....but its definatly not wrong either.

Rep Power: 290 i just downshift by pressing in the clutch, then braking with my other food till the speed gets down to within the range, say to second gear, like an almost stop and then i put the foot on the gas and just let go of the clutch and enable the gears at the right speed. you dont need to double clutch. just make sure when u enter the gear ur within a decent range of speed.
