I have always thought that "granny shifting" is shifting at low RPM instead of winding it out.
Way better fuel mileage but not worth it for the loss of "fun"

Anyone else find that their SS/SC drives MUCH smoother when driven hard?

As i understand it, double shifting is used when your say get into gear at a bad rpm and the engine bogs down ... you slam the clutch while holding the gas then let go of the clutch just as fast as you push it. The result is the rpm's hitting a high level then the clutch gripping hard and you taking off as if you power shifted from the previous gear just not as powerful and without downshifting. This can ruin the clutch like no other method of driving due to the extreme low to high rpm hit. With new cars it is recommended that such a method not be used.

Regular clutching-1)push in clutch 2)shift to next gear 3)lift up on clutch

Double clutching-1) push in clutch 2)take out of gear 3)quick stop in neutral-lift clutch-push clutch back in-switch gear 4) lift clutch pedal
Does not take that much longer to do,no real benefit for most people with newer cars.

Not quite. Double clutching is something that really only comes into play in older cars whose transmissions didn't have synchronizers and such. Double clutching refers to you pushing in the clutch to take the car out of gear, then you put it in neural, let out the clutch, rev the engine up to match where the rpm should be, push the clutch back in, put the car into the next gear, then proceed to go. It really is a long process that needs to be done very quickly to be effective, but a good driver can do it in less than a second. There is no reason for you to do it in a $15,000 2006 vehicle. It is along the lines of rev matching downshifts, which you should do always.

Yes i definetly find it drives MUCH smoother when shifted @ higher RPM's. I find that I think my clutch is slipping sometimes because its so smooth when shifting hard. I hope its not slipping with 6500km's on it. I got it with 5000 on it...

As said before, double-clutching isn't really necessary in newer vehicles. Older transmissions didn't have synchronizers and thus required rev-matching for a good shift. You should try to rev-match your downshifts though, so you're not 'slamming' your clutch.

If you get a chance, listen to an older tractor-trailer when shifting. Those multi-range transmissions weren't synchronized and truckers who drive them need to have double-clutching down to a science. If you think it's hard in a Cobalt, try it with a Spicer 5x3. For those who don't know, that's actually 2 transmissions- a 5-speed and a 3-speed. You start with the 3-speed "brownie" in first, shift through all 5 gears on the "main", shift the brownie into second and the main back first almost simultaneously, then repeat the process... Like this: http://fords.kilonet.org/freightrain/bride1.wmv

Amazingly, you'll notice this guy only uses the clutch when starting from a stop...

how could it not ruin the clutch faster than power shifting or granny shifting?

Because you still only engage it the same amount of times. All you are doing is getting the transmission up to speed so when you re-engage the clutch it doesn't slam into gear and mess things up when they don't perfectly align.

That is power shifting or speed shifting and if you do it alot you will replace the clutch alot.

i thought power shifting is never releasing the gas then slamming the clutch and changing gears asap ... the tranny is already up to speed in the case with power shifting so when done correctly there shouldnt be anything to fear about ruining the clutch as bad as double clutching no?

Why did they put that line in the movie? They are stupid! Any synchro-mesh transmission in a modern car doesn't require double-clutching.

How stupid! Guy who wrote the script knows ****. Guess thats what you get from hanging around ricers!

Ugh.

Lots of bad info here.

1. Double clutching is when you rev match your car when in neutral with the clutch out between shifts.

2. It is useful for downshifting as it REDUCES clutch wear because your revs are always equal if done properly, so there is ZERO clutch slip.

3. It is also the fastest way to downshift without throwing yourself through your windshield.

4. No you don't NEED to do it.

For me its just habit, I do it every single time when I downshift.
