In my youth we used to do it with the old muscle cars: GTOs. Chargers, Mustangs, Hot Rods etc. I mean cars from the 50s, 60s to early 70s. Back then it was called speed shifting. These cars had mechanical clutches and very heavy 3 & 4 speed transmissions. From a standing position we would pop th clutch and from that point on just speed shift. I can't tell you how many transmissions were torn up Friday nights and by Saturday night they were put back together and ready to run for very little money and in about 2 to 3 hours in someones back yard or driveway.

Today with the way transmissions and clutches are built I would suggest using the clutch or have a very big check book.

 

Shouldn't do anything to the car, all you're doing is throwing it into neutral. Just don't put it into gear without the clutch.

 

I thought the same thing. Man, this is a tough crowd. They never forget.

 

I'll agree that if you don't know what you're doing, shifting without the clutch is likely to wreck the transmission, but if you DO know what you're doing, it is not a problem. You simply have to shift into the next gear at the point where the engine speed matches the transmissions input shaft speed, and it's actually pretty easy to do. However, I'm not going to explain how it is done, becaue somebody might be tempted to try it, and blow it, and I don't want to be responsible for them trashing their trans.

You can shift gears without using the clutch and without hurthing the car, IF YOU KNOW HOW. Billman does it, I do it, and I'm sure a few others do it, but if you don't know how it is done then DON"T do it.

 

Even with a constant mesh gearbox, it is not very easy to do. The dog rings can get chewed up.

Street cars need the clutch to be dis-engaged in order to execute a proper shift.

 

Billman and I both understand how a gearbox works, and we both know how to shift without using the clutch or damaging anything in the transmission. It is smack talk to be telling people that it is not possible to do it without damaging the gearbox, so I'm calling on you guys. Billman will back me up. I suspect XViper will too (though he won't post in the public forum, he'll let me know if I get my story wrong, because he watches my back for me).

You WILL tear up the gearbox if you do it improperly, but it IS possible, and it does not have to damage ANYTHING.

Those are the facts, and I'm not about to argue with smack talkers about it, so I'm done with this thread.

 

I talked smack

Why in Gods name would anyone want to shift their car without dis-engaging the clutch in the first place Since Red is no longer posting in this thread, I'll explain why some driver's do it in specially prepared racing cars.

Some driver's utilize a technique called "left foot braking". Left foot braking means that the "heel toe" technique is not utilized. The driver's left foot is used solely for the brake pedal, thus the driver is forced to change gears without the use of the clutch pedal (dis-engaging the clutch)

Not all driver's are left foot braker's. Some driver's utilize the "heel toe" method, hence use the clutch pedal to dis-engage the clutch when performing up and down gear changes. There is no reason in the Universe for a driver who utlilizes the "heel toe" method to not use the bloody clutch to change gears.

If gear changing without dis-engaging the clutch is so easy as Red claims, if he can go around a closed road course "without" using the clutch pedal, except for taking off from a standstill and circuit in less time than me utilizing the clutch on "every" single gear change, I will give Red $500.00 U.S. dollars.

I never said it was impossible to change gears in my previous post, I was just mearly advocating the use of the clutch for executing fast, smooth and proper gear changes.

But what do I know, I'm just a kid who is a smack talker

 

I do it all the time. I thought it was hard at first, but you can up shift and down shift without using the clutch. After you figure it out it's very easy. The trick is to gently let it fall into gear NO FORCING.

It does NOT BREAK anything if done correctly. All cars can shift without using the clutch, the Syncs were designed so that you can shift at any RPM. Am I right?

Truck drivers shift without clutch, it helps the clutch.

 

Is this supposed to help you shift really fast or something

What is the point of not using the clutch?

 

A. lazy to use the clutch in so cal traffic.

B. less wear on the clutch disk.

C. less work on the syncs.

D. lazy to use the clutch in so cal traffic.
