Although the Argentine automotive market took time to adopt it massively, the automatic gearbox was here to stay long ago. There are practically no 0km models that do not offer at least one version with this transmission. Although there are already many drivers who have become accustomed to the automatic gearbox and choose it regularly, many others have not yet experienced it and will naturally have some doubts.

This article aims to provide an overview of the different options offered by the universe of the automatic transmission, both for those who are seriously considering buying a car with this technology and those who are still suspicious or simply curious about it.

What is a car gearbox? What is it for?

To avoid dizziness, let’s start with the basics: the function of a car’s transmission system or gearbox is to alternate gear ratios for optimal engine thrust, depending on the speed you want to drive.

The revolutions of the engine crankshaft are transmitted to the wheels to make them turn, of course, but this relationship is not linear. Since combustion engines work at high revolutions, a device is required to complete the wheels turn more slowly than the engine. Engine and that these revolutions are used as thrust force or torque, especially when starting and driving at low speeds.

Said device, which with the mediation of different gears or “changes” varies the relationship between both regimes, is known as a transmission.

Different gears in the transmission allow for additional gear ratios between the engine and the axles.

Manual gearbox vs. automatic

According to its control, the transmission is classified into two large groups: manual and automatic.

The typical and well-known manual gearboxes force the driver to press the clutch pedal, select the changes with the lever, and be aware of when it is appropriate to do so. They are usually 5 and 6 speeds or relationships.

Automatic gearboxes, in contrast, change gear ratios without input from the driver, who is mainly limited to accelerating, braking, and steering. This comfort, which radically relaxes the driving experience, is the main attraction, argument, and raison d’être of manual gearboxes. More versatile, they usually have between 4 and 10 gear ratios.

How to use the automatic gearbox?

Automatic gearboxes substantially simplify handling but can take power away from the driver over the engine; This translates into the feeling that the car does not respond exactly as we want, both when upshifting and downshifting, especially on the road. It is the reason why many purists still prefer manual boxes. However, as technology advances, this limitation is already being forgotten.

It is due, in part, to the “manual mode” that many automatic gearboxes incorporate, adding an optional configuration to intervene more actively in the passage of changes. In this sense, the impulse modes work – which enables occasional manual interventions without ever stopping automatic changes – and sequential – allows only manual changes, often through paddles on the steering wheel.

The new Peugeot 208 II is one of the many models that offer an automatic gearbox: from the Active version onwards.

The control experience is also enhanced by digitally pre-configured modes for different driving styles: in this sense, the two most common are the “eco” mode – which maintains low revs to save fuel – and the “sport” mode – which, by Instead, it maximizes revs for responsiveness and agility. 

The gear ratios to be applied are changed automatically depending on how you want to drive. In the most sophisticated models, these modes affect the transmission and other mechanical areas such as traction, steering, suspension, and electronic controls.

What are the types of automatic boxes that exist?

There are three automatic transmission technologies :

  • with torque converter,
  • dual-clutch and
  • continuous variation (CVT).

Although all three share the same automatic principle, they differ substantially in the mechanics used to alternate gear ratios without driver intervention.

Automatic transmissions with a torque converter are the most common. However, CVT (continuous variation) automatic transmissions have gained ground in recent years, thanks to Japanese brands such as Nissan and Toyota. The dual-clutch ones are rarer and are usually reserved for a few high-end models. The operation of each one and its advantages and disadvantages will be developed in a future article.

Automatic boxes are usually more technologically sophisticated than manual boxes and, therefore, more expensive. This cost is transferred to the car’s final price, although as its standardization progresses, this impact is increasingly irrelevant. Also, they can be more expensive and complicated to repair, although maintenance is relatively simple and, well done, their durability is guaranteed.

The new Chevrolet Tracker is one of the models that offer an automatic gearbox in most versions.

Automatic gearbox: Is it worth it?

And now the million-dollar question, the existential dilemma: Should I buy or not buy an automatic car?

If you’ve driven your whole life with a manual gearbox, the transition to an automatic gearbox can be resisted and feared, but the truth is that it ends up being a one-way street. Once you get used to the automatic gearbox, the manual will likely be distracting and pointless unless you belong to the tribe of old-school “trailer” drivers.

For urban driving, we recommend that you go for an option with an automatic gearbox if it is within your budget. It’s the future. What yes, we leave you the following tips to take into account:

  • Before buying, know what type of automatic gearbox the chosen model has if it has an impulse or sequential manual mode, steering wheel paddles, and an “eco” and “sport” mode. Any of these variables, beyond costs, will decisively influence your driving experience and fuel management. We don’t necessarily recommend going for the most well-equipped combination – that will depend on your budget – but we recommend fully knowing which features you’re getting and which you’re sacrificing. It will save you disappointment and disappointed expectations.
  • Before deciding, also carry out a test drive to experience driving sensations with different models, types, and functions of an automatic gearbox. In this way, you will know what suits you best and worst, and it will be much easier to make a decision.
  • If you are making the transition from a manual car, the first few times you drive, be careful with your left foot: if you instinctively reach for the clutch pedal before stopping, you will slam the brakes. It takes time (not very long) to adjust to not using this leg when driving.

Note that the condition of the double bond changed. The moving functionality includes optional addition and elimination reactions.

  • When given an alkene: start with the addition
  • When given RX or ROH: start with the elimination

Step 1: We’re given an alkene which means the first step should be addition.

We can do hydrohalogenation (which follows Markovnikov’s rule) using HBr.

Step 2: The alkene went from disubstituted to trisubstituted, which corresponds to a Zaitsev elimination. This can be done using a small strong base such as CH3CH2O– (ethoxide ion, an alkoxide).

Therefore, the best reagents and conditions are:

  1. HBr (hydrohalogenation)
  2. CH3CH2O– (elimination)

After a while, I’m back with ideas to take advantage of our lightbox and learn by playing. Do you dare to continue reading? and be careful what splashes 😉

To see our first chemical reaction, we will need:

  • A transparent source (we have taken the largest one we have from the pyrex type oven)
  • Sodium bicarbonate (depends on the size of the head, the necessary to cover the bottom)
  • Food colorings
  • Medicine syringes from the last time the viruses visited us
  • Vinegar (the cheapest you have at home)
  • Ice bucket to mix colors

We put on our glasses and begin.

  1. We cover the bottom of the transparent source with bicarbonate.
  2. We fill the bucket with vinegar, and with the dyes, we begin to play with the colors; we have left the three basic ones, red, yellow, and blue, and in the rest of the holes, tiny vega has been in charge of making the mixtures and thus see the colors that they went out.

*if you are afraid of stains and then the little ones don’t like to wash their hands, put gloves on them if they won’t because their hands will be transformed, and then it will be difficult to rub them.

  1. Now we are filling the syringes and dropping their contents on the bicarbonate. Ta chan o pspsssspssspsss here we have our first chemical reaction and the best thing, little vegan (3 years old) asked me if we could do another experiment, so the activity was a complete success and more than 30 minutes of entertainment.

What is mean by solved?

1 : to find a solution, explanation, or answer for solve a problem solved the crime. 2 : to pay in full solve a debt. intransitive verb. : to solve something substitute and solve for x

Is solved or has been solved?

“is solved” indicates that it is in the solved state.”has been solved” indicates that the solving of the problem has been completed, which is really just what it means to be in the state of being “solved”

Is solve for grammatically correct?

So you should use the to-infinitive (to solve) in the sentence. Show activity on this post. According to the book entitled ‘Oxford Practice Grammar’ (Intermediate level, 2nd edition, page 362), when using ‘for’ to express purpose, the following sentences are correct: The whole family have gone out for a bike ride.

Is solved an adjective?

solved used as an adjective:
