It s the deal with an automatic car that doesn t shift gears when it hits the accelerator

The gearbox will automatically shift gears when a certain speed is reached.

Automatic transmission, as the name suggests, does not require the driver to manually change gears, and the vehicle will automatically select the appropriate gear according to the speed and traffic conditions.

An automatic transmission uses a planetary gear mechanism to shift gears automatically depending on the degree of accelerator pedal and vehicle speed changes. The driver only needs to control the speed of the vehicle by manipulating the accelerator pedal. Generally speaking, there are the following types of automatic transmissions commonly used in automobiles:

Hydraulic automatic transmission, hydraulic transmission automatic transmission, electric transmission automatic transmission, stepless mechanical automatic transmission and continuously variable mechanical automatic transmission, etc. The most common is a hydraulic automatic transmission. The hydraulic automatic transmission is mainly composed of a hydraulically controlled gear transmission system, which mainly includes two parts: automatic clutch and automatic transmission.

It automatically shifts gears according to the opening of the throttle and changes in vehicle speed.

The continuously variable transmission is composed of two sets of transmission wheels and a transmission belt, which is a kind of automatic transmission, but it can overcome the shortcomings of ordinary automatic transmission, such as "sudden shift", slow throttle response, and high fuel consumption. Compared with the traditional automatic transmission, the structure is simpler, the size is smaller, it can change the transmission ratio freely, so as to achieve the whole process of continuously variable speed, so that the speed of the car changes smoothly, without the traditional transmission when the "pause" feeling.

Manual automatic transmission. It allows high-performance sports cars to be free from the constraints of traditional automatic transmissions, allowing drivers to enjoy the fun of manual gear shifting. This model has a "+" selection gear on its gear.

In D, you can freely change downshifts (-) or upshifts (+) as in manual gears. The driver can force downshifts and slow down like a manual transmission before entering a corner, and can exit the corner with fuel in low and medium gear when exiting a corner.

At a certain speed, the automatic transmission car shifts with the tightness of the throttle. Step on it once and release it again, and then add a gear. I didn't know it at first, but then I always stepped on the Panasonic when overtaking, and I found that the acceleration was fast. to understand. Mine is Honda Fengfan.

Because the gearbox of the automatic transmission will change the speed of its shift according to the force you press the throttle, if you press the throttle deeply, it will automatically sense your movement, thinking that you want it to provide high rpm to achieve the purpose of acceleration, so it will only change gears at high rpm, and then if you take the throttle lightly, it will automatically raise the gear.

Generally, the automatic transmission car should not step on the accelerator too the ordinary road, especially when starting, which will cost fuel, and basically release the throttle and the gearbox will automatically shift when the gear speed is reached!

This is normal, you just get used to it.

There may be several reasons why the automatic transmission car does not go when stepping on the accelerator: 1. The clutch is not closed in place; 2. The hand brake is not put down; 3. The gear is stuck and not fully hung up; 4. The clutch plate is worn.

The average automatic transmission has 6 or 7 gears, which are arranged sequentially from front to rear. They are: P (Parking gear), R (Reverse), N (Neutral), D (Forward gear), and some forward gears include D gear.

Some models have only three forward gears (D) and, if equipped with a four-speed transmission, an overspeed selector switch (O D) is used to turn on the overdrive.

The correct driving method for automatic transmission cars is to put the gear lever in P gear to start the engine, and be sure to step on the brake pedal before you can turn from P gear to other gears, when starting to push the gear lever to a lower gear (that is, 2 or 1 gear, some have 3 gears), after the speed is increased to a certain extent, and then turn into D gear to enter normal driving, if you are cruising at high speed on the highway, you can choose O D gear, you can save fuel.

Hello, what model, the gear does not go, the instrument gear display is normal, the handbrake is loose, it is necessary to consider whether the transmission is short of oil, or the transmission has a problem with me.

Question: The first generation of Sylphy automatic transmission car does not go after the gear, add fuel and go, and drive normally after walking, there is no problem.

Question: Didn't pay attention to the handbrake.

It means whether the handbrake has been released or not.

The handbrake is loose, but the cable bites, resulting in the rear wheel has been biting, you can lift it up to turn the tire, and turn the rear wheel to see if it can rotate normally.

The person who asked to repair the car said that it was a pressure relief and asked me to repair the gearbox, and he also said that he would repair it for 2,000 starts.

I didn't dare to just remove the gearbox.

The transmission oil has not been changed under normal maintenance.

Hello, I'll help you answer this question, the car doesn't go when you step on the accelerator, then this situation is generally caused by a problem with the gearbox electromechanical unit or the related solenoid valve body. If it doesn't work, try the negative pole of the battery line.

Then this is to use the computer to do some decoding, focusing on checking the gearbox electromechanical unit, gearbox program and the gearbox internal solenoid valve body.

It's normal to ask a question over and over again. What does it mean to try the negative pole of the battery wire mentioned above?

This is normal to repeat a few times. What does it mean to try the negative pole of the battery wire mentioned above?

Ask the master, if it is a problem with the solenoid valve, how much can it cost to repair it? Thank you.

Thank you for your question!

The automatic transmission is in gear and does not move when the accelerator is pressed when it is in reverse gear

1. Automatic transmission oil bottom leakage;

2. The connecting rod or cable between the joystick and the rocker arm of the manual valve is loosened, and the manual valve is kept in the neutral or parking position;

3. The oil inlet filter of the oil pump is blocked;

4. Serious leakage of the main oil circuit;

5. The oil pump is damaged. The automatic transmission car is easy to operate and suitable for driving on the stop-and-go road, but the automatic transmission also encounters many problems. For example, regardless of whether the forward gear is in reverse gear, the car just doesn't move, which may be due to oil leakage, clogged filter or damaged oil pump.

Troubleshooting or Troubleshooting Measures:

1. If there is a large amount of hydraulic oil sprayed out of the pressure measuring hole, it means that the oil pressure of the main oil circuit is normal, and the fault is in the input shaft, planetary row or output shaft in the automatic transmission, and the automatic transmission should be disassembled and checked.

2. Check whether the connecting rod or cable between the joystick of the automatic transmission and the rocker arm of the manual valve is loose. If it is loose, it should be reassembled and the joystick should be repositioned.

3. If there is only a small amount of hydraulic oil flowing out of the pressure test hole of the main oil circuit, and the oil pressure is very low or basically no oil pressure, the oil pan should be opened to check whether the oil filter screen of the oil pump is blocked. If there is no blockage, it means that the oil pump is damaged or the main oil circuit is seriously leaking, and the automatic transmission should be disassembled and disassembled.

4. Remove the screw plug on the pressure test hole of the main oil circuit, start the engine, dial the joystick to the forward or reverse gear position, and check whether there is hydraulic oil flowing out of the pressure test hole.

5. If there is a certain oil pressure in the main oil circuit when the cold car starts, but the oil pressure drops significantly after the hot car, it means that the oil pump is too worn and the oil pump should be replaced.

The reason why the automatic transmission car does not move when stepping on the accelerator when it is in reverse gear: the handbrake is not released.

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) Step on 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.

The handbrake did not put.

People who turn on the automatic transmission often forget to let go of the handbrake.

It's possible that something is in the way of the wheels

Summary. Like an automatic car, if the car does not go when the gear is on the accelerator, there are three main reasons, the first is because of the internal damage of your hydraulic distance converter, which causes your power to be unable to transmit to the gearbox, and the second reason is that the oil pump of your gearbox is damaged, resulting in the inability to establish oil pressure in your gearbox normally and cannot be transmitted. The third reason is that there is a problem with the control unit of your gearbox or the mechanical friction plates inside the gearbox are worn, in which case it is generally necessary to open the box to be detected.

However, it is generally necessary to use the computer to test whether there is a fault**, such as the cause of mechanical damage is not particularly common, mainly due to the circuit.

What is the reason why the automatic car does not go when the car steps on the accelerator?

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

However, it is generally necessary to use the computer to test whether there is a fault**, such as the cause of mechanical damage is not particularly common, mainly due to the circuit.

And then the car will shake when it hangs in reverse gear, as if it is not in the back and hits it, and then it will appear in reverse gear?

This should be a shift in the gearbox, and this is still a problem with the gearbox itself.

This is generally because the brake light switch is broken, you can consider replacing the brake light switch, and at the same time check whether there is a short circuit in the line.

Yes, this can be repaired according to the fault code.

It's not usually a broken gearbox, is it? How much does it cost to repair like this?

If you change the brake light switch, it is basically within 200 yuan, which is not a problem with the gearbox.

That is to say, if the brake light switch is replaced, the problem of gear shaking will be solved. Yes.

There may be several reasons why the automatic transmission car does not go when the car steps on the accelerator:

1. The clutch is not closed in place.

2. The hand brake is not put down;

3. The gear is stuck and not fully hung up;

4. The clutch plate is worn.

The correct driving method for automatic transmission cars is to start the engine after the gear lever is placed in P gear, and the brake pedal must be pressed to turn from P gear to other gears, and the gear lever should be pushed to a lower gear (that is, 2 or 1 gear, some have 3 gears) when starting, and after the speed is increased to a certain extent, then turn into D gear to enter normal driving, if you are cruising at high speed on the highway, you can choose O D gear, which can save fuel.

Here are a few things to keep in mind when getting started.

1. Shift gears after pressing the brake pedal and check whether the gear selector lever is in the correct position.

2. When starting over the bulge or steps, it is best to press the brake pedal with the right foot, relax the right foot slightly while the right foot slightly press the accelerator pedal in the stationary state of the car, and immediately lift the right foot and lightly press the brake pedal at the moment of crossing the step to prevent the vehicle from shaking seriously.

3. Don't get too high the engine speed when starting. Especially in winter, when the air conditioner is working rapidly, the idle speed may exceed 1500r min (generally 1000r min), which will cause strong vibration and advance gear impact, resulting in a rapid start. Therefore, it is necessary to wait for the engine speed to slow down before starting.

This is an automatic transmission control strategy, and now the car has been partially intelligent, and the computer will guess the driver's intentions and control the engine and automatic transmission according to the driver's intentions.

In the transmission control strategy, there is such a rule that increasing the throttle in an instant means that the driver wants to accelerate fast and hopes that the engine can provide instantaneous surging power, then the transmission computer will control the transmission to increase the shift point to maximize the instantaneous acceleration (for example, in the past, it was 2000 rpm upshift, and in power mode, it will be increased to 3000 rpm).

In fact, there is no need to force the upshift and downshift of the car when you are driving, the computer will choose a balance between comfort, fuel consumption and power to achieve automation. Of course, the power mode will increase the power at a high shift point, but it will also increase fuel consumption. Switching to a low shift point can reduce fuel consumption.

Automatic transmission: Remember to drive and fuel smoothly, the computer will guess the driver's intentions, otherwise comfort and fuel consumption will inevitably increase.
