The automatic transmission is uphill and the power is insufficient, how to change gears?

If you have a manual transmission, you can go uphill by manually adjusting it to first gear. Of course, sometimes you will also use the second or third gear, if the slope is not so steep, then you can use the second or third gear, if the slope is very steep, you can use the first gear, although the speed of the first gear is not very fast, but the first gear has one of the biggest advantages is that the power is relatively large, which is like saying that a person with great strength, the speed of running is not so fast, a person with not a lot of strength, the speed of running may be very fast. <>

In fact, the same is true for automatic transmissions, generally speaking, automatic transmissions will automatically match the gears according to the current road conditions, but they can also be converted to manual. If you are worried about not going up, then you can use the manual transmission to shift at this time, at this time we will easily go uphill, remember to add a little oil when going uphill, but refueling can not be too much, just like riding an electric car, you can give a little bit of slow uphill, but can not add too fast, if it is too fast, then this speed we can not brake, therefore, it may cause very serious consequences.

Automatic cars, if not replaced in place, may cause car destruction and death, the situation is still more serious. Generally speaking, the automatic transmission has only one forward gear, and the transmission will automatically switch into place during the climb, so under normal circumstances, there is no problem going uphill. Because gearboxes are smarter than people.

So in general, we can also believe in the gearbox, we can believe in the effect of the machine, but if their psychological factors can't pass, then they can also change to manual transmission, because the average person will have a higher degree of trust in themselves. So if you think you can quickly change gears, you can also choose to change them yourself. But the manual mode may not be reasonable, so it's up to you.

If it really doesn't work, it is recommended to buy a manual transmission car, now automatic is a trend, but manual transmission cars are cheaper, and the average person is more accustomed to manual transmission, so it can't be changed for a while.

If the dynamic gear is insufficient when going uphill, it probably needs to be properly shifted. You can go up to 3rd or 4th gear, so you can usually go up all the slopes.

It should be changed to L gear, because L gear is more powerful and can provide more power.

Climb with first gear, although the first gear is the slower, but the first gear has the best grip.

If it is an automatic transmission car, when going downhill, the speed will gradually become faster without putting on the gas pedal. This is mainly due to the influence of gravity, the car does not actually have any braking measures at this time. At this time, as long as the friction on the ground does not exceed the acceleration caused by gravity, the speed of the car will become faster and faster.

Because the speed of the car is mainly reflected in the speed of the engine and the exclusive aspect of the gearbox itself, if it is in a long downhill slope, then it will naturally be affected by gravity, and the speed is getting faster and faster. <>

First, the unique presence of automatic transmission cars.

If you learn the driver's license earlier, you can find that at the beginning, you learned manual transmission cars, and the reason why manual transmission cars were more popular at the beginning. Mainly because at that time, our research on clutch and gearbox was not as deep as it is now, and it was necessary to continuously shift the car to achieve continuous acceleration between multiple gears, and at the same time reduce fuel consumption. But at the same time, if the gear is not in the right position, the gearbox will brake us.

But automatic cars don't have such an advantage. <>

Second, when going downhill, you can't put the gear in D gear.

So if you are driving by yourself and there is a long steep slope ahead, remember not to put your gear in D gear. Because if we don't pay attention to the road conditions, the car will keep rolling forward, and it will get faster and faster. The only way to get to the late stage of automaticity is to engage reverse gear and then press the throttle.

Third, what do you think about automatic and manual transmissions?

First of all, I think that automatic transmission and manual transmission have their own advantages and disadvantages, of course, the advantages of automatic transmission will be greater, which can be seen from now to the market holdings, automatic transmission is gradually occupying the mainstream of the market. Although the manual transmission will be more advantageous in terms of operation and when climbing mountains, it will be more convenient to drive between cities and free your left foot.

The speed will get faster and faster, and eventually it will get out of control. Because the downhill slope has gravity involved, it has the effect of assisting.

At this time, the speed will be faster, but it will be slower than in neutral, because the engine will have a certain braking effect.

At this point, the speed will be slower than when the car is in neutral because of the engine braking.

Upshifting is easier than usual, and requires lower RPM than usual, and once you move up high gear, the speed of the car is increased again, and in this case, the acceleration formed on the steep slope will make the car faster and faster. For a normal six-speed automatic transmission, it would take about 80 km/h on the flat road to reach the top sixth gear, but on downhill conditions, it may only take 60 km/h to get to sixth gear. The speed of the vehicle decreases very quickly and is generally not used.

The speed range of different gears is different, if you don't use the brakes to control the speed, the speed will only get faster and faster when going down a steep hill, so you have to brake frequently to control the speed, but this will bring another problem, brake thermal decay. It's a bad feeling, which means that even the manual mode gearbox shifts gears under its own set of logic. When the speed is not high enough, it ignores the manual upshift command and does not upshift; When the rev is not low enough, it does not immediately respond to the downshift command (delayed response downshift).

But the speed of the car will still rise to a value, and the speed will continue to rise at this time, and it will not rise again after rising to a value, but the sound of the engine is quite loud when the speed comes up. However, because it is a mountain road, it is still necessary to assist the braking to achieve a smooth speed. If your slope is greater than 25 degrees or so, then you must be in low gear, and the speed will be faster and faster, because he, the continuous downhill gravity acceleration is greater than the torque of your gearbox and engine, and the speed of the car will be faster and faster.

Because of the resistance of the engine, as long as the slope is small, the speed of the car will not become faster, so you can drive with confidence. However, if this slope is shaky and long, it is recommended not to hang the D gear, there is a potential safety hazard, you can hang it in the L gear or gear to prevent the brake pads from overheating and causing brake failure. Release the brake speed will be up immediately, you can hang to the S gear, no refueling, the general speed can be lowered, if you feel that the speed is still fast, you can hang the L gear, as long as you don't refuel, this gear as long as you don't refuel,

No. Because automatic transmission cars generally have a steep hill descent function, when going downhill, the gear will be lowered, so it will not automatically upshift.

No. When the automatic transmission model is hung in "D gear" downhill, for example, we start at 50% throttle, because it is downhill, the power demand is small, the speed rises quickly, and the transmission will quickly upshift; In order to control the speed of the car, we will choose to reduce the throttle, and reducing the throttle will cause the transmission to upshift faster.

Automatic shifting is related to several factors, mainly related to throttle opening, vehicle speed, and load. At any speed, regardless of whether the valve is added or not, the transmission computer will control and select a reasonable gear, so that 30kmh is not in 5th gear and 80kmh is not in 3rd gear. Even in manual mode, if the speed is low and the driver does not downshift, the transmission will automatically downshift, which is its protection program.

Downhill vehicles have a small load, are fast, and have a small throttle opening. These factors are the conditions for the transmission to upshift. The speed will get faster and faster, and the gear will get higher and higher.

Volkswagen Lavida little test question: What is the reason for the low speed and high speed of the Volkswagen Lavida test question? Her main cause was a slippage of the clutch plate. If yours is manual, then it is caused by the slippage of the clutch plate, and you can only hear that the engine speed is high and the car cannot drive.

If you're automatic, then there's something wrong with the classic control unit inside your gearbox, and he won't give it to the engine. The gearbox jumps gears, so to speak. His was a problem with the gearbox's electromechanical control unit, putting its film unit.

Not to mention that you can.

1.Automatic shifts operate correctly when going uphill:

1) P gear is the parking gear, R is the reverse gear, N gear is neutral, D4 is the normal forward gear, D3 is the normal forward gear when the mountain road, curve, continuous downhill road and other roads need high power or need engine braking, and the forward gear is the forward gear when the snow and mud are bad, large power or abnormal use.

2) When P gear shifts into R gear, you need to press the gear lever button and step on the brake to change in, R gear needs to press the gear lever button and step on the brake to shift in N gear, N gear can be shifted into D4 and pulled in (it is recommended to press the gear lever button), D4 to shift into D3 only need to pull into D3 gear, and D3 needs to press the gear lever button to shift in. Do not coast in neutral while driving!

3) So to shift from D gear to D2 or D1 gear, you only need to press the gear lever button and pull it directly into gear. The same way to change gears from 1st to D gear.

2.Automatic Transmission Driving Tips:

1) Turn the key 1 (or 2) square; Many lights on the dashboard turn on, and the computer in the car starts to self-test (equivalent to the start of the PC), and at the same time, the oil pump starts to work. After a few seconds, the lights go out. Depending on the car, some lights will not go out until they are ignited.

2) Apply the brakes and ignite.

3) When the engine idle speed drops to normal speed and the water temperature gauge pointer starts to move, press the brake, hang D gear, and release the handbrake.

4) Release the brakes and go. The above ignition process is also applicable to cars with manual transmissions, but cars with manual transmissions must step on the clutch to ignite. If you think that the little bit of gasoline burned by the eco-friendly or hot car is more important than the engine life, skip the hot car step.

5) Just like in computer games, press the accelerator to accelerate and press the brake to slow down.

6) When encountering a red light or other reasons, you need to stop for a short time, and apply the brakes to keep the car stationary. Release the brakes to start.

7) Stopping for a long time, such as waiting for a train to pass at a railroad crossing, or clearly knowing that this red light is very long; See point 1. (There used to be an opinion that it was better to shift into the n position and tighten the hand brake when stopping for a long time.)

Uphill in D gear, the main damage is not to the gearbox, but to the engine. It's like who's going to climb a hill with the 5th gear of a manual car?!

The automatic transmission of Sail is a four-speed gearbox, D gear is 1-4 gears, 3 gears are 1-3 gears, 2 gears are 1-2 gears, and 1st gear only stays in 1st gear and "can't move". You can shift gears without stepping on the brakes while driving, but you can only change in the forward gear, just release the accelerator and pull the gear knob, and it is best to shift one gear at a time. For example, if you see a steep slope ahead, if you are not sure (or unlikely) to increase your speed, you can slow down in front of the slope and shift to 2nd gear as you slow down.

Walking on the mountain road, there are both uphill and downhill, you can choose between 3rd gear or 2nd gear (depending on the size of the slope), so that the engine is effortless when going uphill, and you can also get a fuel-saving effect by releasing the throttle when coasting downhill.

Because the automatic transmission is more convenient to operate, many people prefer the automatic transmission type when buying a car, but the automatic transmission is easy to have the problem of insufficient power when going uphill, and the lack of power can easily lead to the landslide of the automatic transmission car, resulting in the occurrence of potential safety hazards. Therefore, when going uphill, if you encounter insufficient power, taking gear shift measures is also a problem that many car owners are very concerned about. In fact, in order to avoid the occurrence of this phenomenon, when the automatic transmission encounters insufficient horsepower, it can be switched to manual mode or climbing mode through paddle shifting, and successfully climbing.

When going uphill, if the automatic transmission is insufficient in power, if there are paddle shifts inside the vehicle, it is recommended that the owner continuously shift the paddles to shift the gear to the lowest gear, so as to provide the maximum power output for the vehicle. Avoid slipping slopes. In addition, if the vehicle has a manual mode, i.e. M gear, it should immediately switch to M gear in case of lack of power.

The principle is the same as paddle shifting, which provides maximum torque to the vehicle and prevents the vehicle from landslides. Another advantage of this mode is that it can lock the gears and automatically upshift only when the gearbox's protection function is activated, which also provides more safety for the vehicle. <>

Of course, if the vehicle only has L gear, that is, the climbing mode, when the climbing power is insufficient, you can first step on the brakes, and then lower the gear to change to L gear, and then continue to drive normally. Of course, you can also hang L gear directly without stepping on the brakes, but such an operation will also have great consequences, that is, when switching gears, it will have a greater impact on the gearbox, so that the car will be irreversibly damaged. There is also a gear limit in the L gear, and generally the lower gear allows for more torque, allowing the car to maintain maximum power and climb smoothly.

Finally, no matter which gear you switch to, it should be operated according to the specific shift mode inside the vehicle. Don't panic too much when you encounter a lack of power when climbing, follow these steps and take specific gear shifting methods to climb smoothly and avoid accidents.
