Wut is double clutching

Wut the hell is double clutching

p.s i did not know where to ask this question

Double clutching is used for operating a "crash-box" in other words, a gear box that has un-synchronized gears. Since all cars I know of these days have synced boxes, it is a useless technique, there is no reason to do it, unless you want to waste time or are driving a very large truck.
Basically, you press the clutch, put the gearbox in neutral, release the clutch, press the clutch again and then put it into gear.

hmm just cuz in the fast and the furious Vin Deasil says to paul walker, " GRANNY SHIFTING!... not double clutching like yah should." so i wias like wut the hell does that mean

The writers had bad information from people that had no idea what they are talking about. I think the idea they were trying to convey was speed shifting. This is where you shift without using the clutch. This can be a quick way to kill a gearbox and you have to be pretty good to pull it off. I have seen it done, my dad can do it.

My uncle showed me how too. You keep the RPMs at one place and you can shift. But if the RPM's move you mess it all up. :bigthumb:

Yes speed shifting was used primarily for crash boxes too. When VW first came out, skipping the double clutching (or any use of the clutch except for starting from first) and just shifting was popular with alot of owners, even after the boxes got synchronizers, VW beetle owners continued speed shifting - it's not too hard so long as you're familiar with your car.

out of curiosity, would the '67 mustang 3-speed transmission i'm about to get require double-clutching?

They're right about the double clutching info stated above. It's only relevent on old cars before syncros. An old mustang like that would probably need double clutching, but I dunno off hand. As far as speed shifting and shifting with out using the clutch goes, right again. I wouldn't recommend it for regular use as it is pretty hard on the gearbox, but it does work. It's pretty much the same thing as "half clutching" which is when you just push the clutch down enough to get the shifter to move. I remember in my 86 Z, I couldn't do ANYTHING without pushing the clutch some...it wouldn't let me even attempt moving to the next gear. That why I started half clutching it when racing. It works...I never had any problems with my car...but it was a nissan...and nissans are the ultimate shizass. If you wanna try something that takes true skill, try to learn heel and toe shifting...

Synchros have been out for a LOOOOONNNNG time.
My '51 Ford Tudor custom had them.
Double clutching is usually only reserved for either real (like before your parents were born)old cars and older semi trucks.
The cars you guys are talking about are designed for anybody from a 16 year old kid to an 86 year old lady to successfully shift.
Alla that fancy clutching and jam-shifting stuff is just a waste of time on newer cars.

This thread is from 5 months ago... :eek7:

If I had an old rig with manual trans...

That shifted hard or ground-me-a-pound
when trying to shift...I would double-clutch...

It is when you push the clutch in once to take the rig out of gear...and again to place in gear...

double pushing the clutch...

We used to drive 6cyl. sticks in the 60's
in Chevy's and would tear around parkng lots in hot pursuit of one another...all at high rpms...

Oh for the good old days... :o)
