Langdong automatic gear from forward gear to reverse gear, there is a sense of frustration, what is

Automatic transmission cars.

The reasons for the frustration of shifting are as follows:

1. The internal clutch of the gearbox.

Stress relief. Inspect the clutch for damage and repair it.

2. The oil circuit of the gearbox is not smooth. The oil circuit plate is worn, the gearbox has not been replaced for a long time, it has deteriorated, the lubrication effect has decreased, the gearbox filter screen is too dirty, and the filtration effect is not good, so that the wear fine matter enters the valve body.

3.Transmission fluid is not added to the standard. Confirm whether the transmission oil is added to the standard, if the transmission oil is less or too much will lead to this failure, there is a transmission dipstick can check whether the transmission dipstick is on the standard scale when the vehicle starts.

4. The solenoid valve is damaged. There is sludge circulating in the transmission oil in the transmission.

If the oil passage in the valve body is blocked, there will be a problem of frustration, which will lead to a series of transmission problems such as high temperature, impact, and slippage of the gearbox over time.

The stuttering of an automatic transmission is a problem caused by a combination of factors, not only the backlash of speed and torque.

The timing of the gear shift is mainly controlled by your own feet.

First, during the acceleration operation, the automatic transmission is generally shifted at 2500 --- 3000 rpm.

Second, during slow acceleration operation, the automatic transmission is generally shifted at 1500 --- 2200 rpm.

Third, the trick to solve the frustration of shifting: the essentials of your slow acceleration operation, that is------ "slow refueling lightly lifting your feet, and then refueling", the timing of automatic gear shift is generally controlled within low speed, which well solves the frustration of shifting. If the problem is not solved, or there are car failures and auto parts problems that have not been solved, search for "car repair and ask" on the WeChat public platform, and the technical team can answer you in detail for free.

Summary. There is no problem if this situation occurs by chance, with a 6AT gearbox, there is some occasional frustration when changing the first gear to the second gear, and there is no problem with the smooth shift above the second gear. When changing from first gear to second gear, the shift ratio changes too much, and the oil pressure control deviates, resulting in a frustration.

As long as there is no such feeling every shift, there is no problem, every shift has or other gear shifts also have a pause, it is a problem with the valve body, and the valve body needs to be cleaned or replaced. The car must be changed every 60,000 kilometers, and it must use Volkswagen's original oil or Aisin's 6hp, and the transmission filter must be replaced every two times. Using the gravity oil change method, 4 liters of oil are required, and the cost is 500 yuan.

I am a modern Langdong, 15 years of running 80,000 kilometers master, a month ago to change the gearbox oil, the circulation machine replaced, after the replacement I see that the circulation machine replacement is harmful to the gearbox is true, master, if the circulation machine is replaced with damage, wouldn't it be more spent money and destroyed the car, but it will be troublesome.

The circulating machine has no damage to the gearbox, the circulating machine has no problems with the gearbox after the oil change, and the oil has not been changed for a long time, at this time, a lot of impurities and sludge will be deposited inside the gearbox, after the use of the circulating machine is replaced, the sludge is cleaned up, which will lead to the deviation of the control of the valve body by the gearbox computer, at this time, there will be no jump gear or serious impact of the jump, and there is also a situation that the gearbox itself has been seriously worn, and the cleaning will cause the matching gap to be too large, resulting in oil leakage. Once this situation occurs, you need to repair the gearbox, and your car is only 80,000 kilometers, and there will be no such problem.

Okay master, I know, I'm sorry master.

1 km is fine, as long as the speed does not exceed 30 km/h, if the speed is too fast, it will cause the gearbox to burn out due to insufficient lubrication and internal friction plates. If the number of kilometers dragged is too far, you must take a break for 5 10 minutes halfway, and then hit the motor and let the motor work for 5 seconds, so that the gearbox can be lubricated to prevent the gearbox from burning out.

The frustration of the Lavida automatic transmission starting gear may be caused by the following reasons:

1.Problems with shift procedures. If the driver suddenly increases speed when he presses the accelerator pedal at the start, and then decreases sharply when he releases the accelerator, the gear change procedure is incorrect.

At this time, you can increase the depth of the accelerator pedal to smooth out the fluctuation of engine speed before shifting, which can effectively reduce the frustration.

2.Driving environment issues. The frustration of starting gear may also be related to the road situation, such as when driving on a slope, when stopping and accelerating, there will be a frustration, so try to operate on a smooth road section to alleviate the frustration.

3.Driving status issues. Some drivers react too hard or too quickly when the throttle is at the start, causing the engine to accelerate violently, and when the engine returns to low speed, due to the different speeds of the front and rear wheels, there will be a violent shaking or bumpy feeling.

It is recommended to use the accelerator pedal slowly when accelerating, especially when starting, and it is not recommended to press the accelerator hard.

4.Vehicle maintenance issues. If the frustration of the vehicle's Lavida automatic transmission hand or gear pause is more obvious, it may be related to vehicle maintenance, you can check whether the valve clearance is normal, the vehicle matching status or whether the transmission oil is clean or replaced, etc.

In short, the throttle sensitivity after gear shift can be appropriately adjusted to improve the smoothness of driving operation, and the car can be repaired and inspected appropriately to ensure driving safety.

The reasons for the frustration of automatic shifting are as follows:

Clutch pressure relief:

Internal transmission clutch pressure relief. Inspect the clutch for damage and repair it.

Issuance of oil road cards:

The oil circuit of the transmission is not smooth. The oil circuit is worn, the gearbox is not replaced for a long time, it deteriorates, the lubrication effect is reduced, the gearbox filter screen is too dirty, and the filtration effect is not good, so that the worn fine substances enter the valve body.

Transmission oil not added to the standard:

Confirm that transmission oil is added to the standard. This failure occurs if there is too little or too little transmission oil. If you have a transmission dipstick, check that the transmission dipstick is on the standard scale when the vehicle starts.

Damaged solenoid valve:

There is sludge in the transmission oil circulating in the gearbox to block the oil circuit in the valve body, which will cause a series of problems such as high temperature, impact, and slippage in the gearbox for a long time.

There is a malfunction in the vehicle's transmission oil. The transmission oil of the vehicle has failed, and the transmission oil must be replaced regularly after being used for a long time; The gearbox gear of the vehicle is seriously worn and needs to be repaired; The oil-off coordination is not done well, resulting in the rev speed not being in the optimal gear when shifting.

What does it mean to change gears? The so-called shift frustration is caused by the problem of throttle clutch coordination, not the fault of the vehicle itself. Here's a little trick, because the sound of the vehicle's engine is different at different speeds, so novices should familiarize themselves with the relationship between sound and rpm as soon as possible when driving.

In the early stage, you can take a look at the tachometer a little, and the speed will be upshifted when the speed breaks 2000, and the pure speed of the early town will be downshifted if it is lower than 1200. Gear shifting is based on the speed, not the driving speed. At the same time, the owner should pay more attention to the condition of the transmission oil, preferably every 10,000 kilometers.

Long-term use of transmission fluid not only does not protect the vehicle's transmission, but can accelerate damage.

It is usually caused by shift lag, check whether the transmission oil, shift solenoid valve, accumulator spring, etc. are normal.
