Shifting Gears Smoothly: Balancing Gas & Clutch Release While Accelerating & Reducing RPMs

I noticed that when shifting up to a higher gear, in order to reduce jerking and smoothly accelerate, you need to start slightly adding gas in the final phase of releasing the clutch. Everything happens very smoothly and without jerking. When it comes to reductions, the same is true, but a bit more gas depending on the gear / RPM.

There is also a second school that only speaks gas after releasing the clutch completely.

Is my technique correct?

Yes, I drive myself like this and when changing the oil in the box, I looked at the clutch and it does not look very worn.

You reduce the jerks, so also the torque that must be transferred by the gearbox and the clutch to adjust the engine to the gearbox revolutions, so correctly as possible. The joints and the clutch will reward you with longer work.

Using this technique (I can't imagine another one) you can drive even without a clutch.
Sometimes it is necessary.

I also run like that and after 170,000. km, I had to replace the clutch because the pressure broke. The dial was not too worn out yet.

During each driving license course, they "teach" that you can add gas only after the clutch is fully released after changing gear.

But for me it is a bit pointless, because when accelerating, we have to lose that extra second and brake the engine at this time, instead of smoothly while releasing the clutch (as it starts to catch) gradually add gas. The whole thing takes 1-2 seconds, so there is probably no question of the clutch slipping.

I'm right?

I just advise you, because he is still fresh when it comes to drivers. During the course, they instilled in me another method, i.e. complete unclogging of the clutch and only then the gas.

This means that the owners of these course vehicles want to spend a lot on mechanics or have dealings with them :D

Drive as we write here and the car will be grateful to you.

They teach different methods to keep themselves comfortable and safe.
Remember how they taught that you must not drive to intersections with lights "at ease", and how is it in practice after many years?
Yes, in the case of braking it is right, but in the end you should reduce gears, because you can't drive slowly on the 5th wheel and you had to do that.
Will each of you start off manual after years? or maybe no one.

Even during the exam I didn't move like that. It's uncomfortable with manual removal and that's it. Once you've mastered where to take the clutch, the manual is very rarely used.

It made sense on cars with a carburetor. In modern cars, there is no problem with starting without adding gas or holding the car in place on virtually any hill only by operating the clutch and not touching the gas or brake.

As for the technique of shifting, the reduction is as much as possible with "mid-gas", but when selecting a higher gear, if it is done efficiently, there is no need for it, because the revs will not have time to drop. In courses, they teach you not to accelerate until you let go of the clutch. Generally, when shifting to a higher engine speed, the engine speed must drop, so the gas is released (although not necessarily to zero) and not added.

It also depends on the car, in any diesel I could not change the gear without a clutch, while in the old Punta I was able to change both ways without any scratching without using the clutch (I learned from a must, because on the road my bearing broke, somehow it still worked there leftovers but I only used it to move), of course "up" is much easier than "down". When reducing, you need to add gas in neutral.

At the course, I used the 2008 Renewal and there was no option up the hill that it would not go out without gas.

But why burn the clutch?

For now, the only diesel I have tried is my Passat B4 (1994), it goes up nicely without a clutch, but it grinds downwards. I still have to train

My predecessors apparently did not understand what I was saying ...

I only found that it was possible, anyway, at idle speed (I wrote that without touching the gas) it's hard to burn the clutch.

Rather, I meant the idle control system in cars with electronic fuel injection, where in the event of increasing the engine load, the engine controller will "gas" itself to maintain idle speed.

The revs will not drop in time, but what if the engine works as a brake after full engagement ...

When driving at 40 km / h in 2nd gear, the revs are higher than at the same speed in 3rd gear, so in order to avoid a jerk, they must drop to the appropriate level when changing gear. If they fall too much - there will be a jerk, if they fall too little - there will also be a jerk. Sensing the right moment, you can simply release the clutch with one move, instead of slowly releasing it (as when starting) and adding gas at the same time. Do not add theory to the courses, because they teach beginners and teach you not to add the throttle before the clutch is released (so that the engine does not scream at high speed and the clutch does not burn).

To save the gearbox and the clutch, gears should be changed so that it transmits as little driving torque as possible when engaging and disengaging the clutch.

The possibility and degree of difficulty of shifting gears without a clutch depends on the construction of the gearbox and its gear ratios and the speed of the engine's response to the accelerator pedal. In the long run, in the "civil" chest, it damages the synchronizers.

I drove a few Fiats, Opel and VW and on a smooth road I could reach 3rd gear without touching the gas, it was always possible to start with 1st gear without gas, even in the driveway. Most of them were cars with engines with a capacity of not more than 1.4.
