Automatic transmission trailer, with P gear, should have no problem with the front wheel frame and t

If it is a front-wheel drive model, there is no problem with the front wheels being dragged off the ground, and the rear wheels do not have a transmission shaft, and there is no connection with the front wheels, so they can be dragged casually. Just let go of the handbrake. Rear-wheel drive models on the contrary, four-wheel drive models don't know, no money, can't afford to buy.

Reply 8 The front wheels are empty, it doesn't matter, the transmission shaft does not touch the ground, which is equal to parking, so it doesn't matter if the p-hung n, the hand brake must be released, and then the wheel grinds the brake How many kilometers does the automatic neutral traction not exceed how many kilometers, which refers to direct traction, which is indirect traction.

The following are detailed as follows: P (Parking) Parking Gear, or Parking Gear: P is used for parking, which is the use of a mechanical device to lock the rotating part of the car so that the car cannot move.

As long as the gear selector lever is in the driving position while the engine is running, the automatic transmission car can easily walk. When parked, the gear selector lever must be pulled into the p-position, which locks the output shaft through the parking brake device inside the transmission and tightens the hand brake to prevent the car from moving. When the car needs to stay in a fixed position for a long time, or before leaving the vehicle after stopping, the hand brake should be applied and the paddle lever should be pushed into the "P" position.

It is important to note that the vehicle must not use the P gear until it is completely stopped, otherwise the mechanical parts of the automatic transmission will be damaged. When you don't use it, the gear is there, and the wheels are mechanically locked to prevent them from slipping.

In addition, the automatic transmission car is equipped with a neutral start switch, so that the car can only start the engine in the "P" or "N" gear, so as to avoid the car suddenly moving forward when starting in other gears.

There is harm. Automatic.

If the car is in P gear, it is completely impossible to tow the trailer, and if it is in the P gear, P is parking, which is equivalent to the handbrake in the manual gear.

Put the gear on this car and you won't be able to push it. That is, the parking gear, which can replace the handbrake. The gearbox at this time.

It is locked, and if you change gears when towing the car, the car will already have irreparable damage when it is towed.

Many riders are accustomed to setting the gear in D gear when using an automatic transmission car.

However, if you encounter a towing situation, the internal structure of the engine and gearbox and the overall load of the car are resistant to each other, which is very bad for the car.

After the analysis of each gear, generally speaking, the trailer is the most scientific on the N gear, N is the neutral neutral, and the neutral of the manual transmission has a meaning, which is used for a short period of parking. This reduces the chance of damage to your car's gearbox.

The trailer cannot be in P gear, it should be in neutral gear. It can cause damage to the gears of the variable box.

If you find a towing company to claim the handlebars, the gearbox should be damaged, (basically it can be handled according to the premium).

Summary. Dear, this gearbox can't be said to be bad, but there is a lot of damage to this gear of this gearbox for yours. Especially for this locking mechanism in the P file.

Will the gearbox be damaged if there is a gearbox of about 10 meters when driving in P gear?

Dear, this dust Jingmin gearbox can't be said to be bad, but the manuscript quietly has a lot of damage to the gears of your gearbox. Especially for this locking mechanism in the P file.

At this time, the gear of the car is in P gear, which will damage the gear in the transmission source box, which will cause chaos in the gear and damage to the gearbox.

How to tell if the gear is bad or not.

How can you tell if the gearbox is broken or not?

1. Gearbox fault light prompt and alarm: This situation is generally the failure of the electric control unit or the failure of the mechanical unit of the gearbox. 2. Spring old slippery:

Stepping on the accelerator, the engine speed increases, and the speed does not go up 3. Setback: the car has a sense of impact and frustration when shifting up and downshifting, or a feeling of jamming and cowardly driving when accelerating4. Shift delay; Some cars are delayed in shifting gears because the oil is changing and the oil is up and the oil pressure is insufficient, and in many cases changing the transmission oil can solve the problem.

Automatic. 5. Abnormal noise: abnormal noise after the car is driven, the reason may be that the gear or bearing in the gearbox is too stressed or the material is not good, or it may be caused by the contact surface of some metal parts is not smooth enough, this situation should be checked and repaired in time, otherwise the damage area will be expanded.

6. High temperature of the gearbox: Usually during driving, the dashboard prompts that the temperature of the gearbox is too high, as long as there is a prompt, the temperature has reached more than 120 degrees. 7. After the gear is hung, the shirt turns off when it hits the machine

The one-way clutch card in the torque converter or the year is dead, and it cannot play a one-way torque increase role.

Pro, the above reasons can judge whether the gearbox is damaged, the gearbox finger trace failure precursor to grasp the best time to deal with, some may be through only Wang and oil change can be better, some of the Ling file needs to have a professional maintenance master to deal with.

1.Automatic transmission car can hang up reverse gear and P gear during driving, but it is absolutely not allowed, automatic transmission P gear is a lock gear, P gear has a locking mechanism in the gearbox when locking the gearbox output gear, that is, locking the transmission part, if the vehicle is running into the P gear, the gearbox gear is worn sharply, or there is an abnormal sound, and the gearbox and the transmission part are damaged and scrapped.

How to use the file:

The P gear is used for parking, and it uses a mechanical device to lock the rotating part of the car, so that the car cannot move. When the car needs to stay in a fixed position for a long time, or before leaving the vehicle after stopping, the hand brake should be applied and the paddle lever should be pushed into the "P" position. Generally, we will only put the vehicle in P gear if it is parked in the parking lot for a long time, or somewhere to prevent the vehicle from moving, and at the same time, we must also pull the handbrake.

Extended Materials. Precautions for the use of automatic transmission cars.

The automatic transmission control area is being loaded.

1. Try to avoid using automatic mode, because in the case of hot weather in summer, the automatic transmission will be in danger of overheating, which will also cause **; Because the automatic mode requires 1 times more revs than the manual mode, this can lead to the danger of the automatic transmission overheating**.

2. When driving at high speed, you should also try to avoid using automatic mode, which will also lead to the danger of overheating the automatic transmission due to long-term operation.

3. Should try to avoid overtaking with refueling, which will also lead to the danger of overheating the automatic transmission, in case of overtaking, cut into the manual mode to lower one gear or two gears of throttle to the end of the speed on the power output can also be light overtaking.

4. The practical S mode should be avoided as much as possible, that is, (sports mode), why the sports mode can only exert 10% of the power output at most, and the speed can not be controlled by himself like the manual mode, and this will also lead to the gearbox hot or more dangerous or even the danger of the cylinder boiler. Case: In late 2012, a car owner used the sports mode for a long time and the automatic mode has been used at high speed, resulting in an automatic transmission, and the temperature was too high, resulting in 1 death and 8 injuries.

When going uphill, you should switch into manual mode, and one gear down is enough.

Some drivers slide the gear lever to N gear (neutral) when driving at high speeds or downhill in order to save fuel, which is likely to burn out the transmission. Because the speed of the output shaft of the transmission is very high at this time, and the engine is running at idle speed, the oil supply of the transmission oil pump is insufficient, and the lubrication condition deteriorates, and for the multi-plate clutch inside the transmission, although the power has been cut off, the passive plate runs at high speed under the drive of the wheel, which is easy to cause resonance and slippage, and produces adverse consequences.

Matter... The P gear has a locking gear that doesn't allow the car to move, which is probably damaged.

The P gear structure of the automatic transmission belongs to neutral gear+, and a set of ratchet pawl occlusion structure is designed in the neutral state, which is used to assist the vehicle to brake when the hand brake fails, so as to ensure that the vehicle will not slip.

In other words, when the P gear is engaged while driving, it is actually in neutral mode, plus the locked state. However, the internal gear is running at high speed in high-speed driving, although the ratchet is designed with a lot of grooves, it is difficult for the pawl to snap into the ratchet under high-speed rotation, so even if the P gear is hung up, the pawl is stuck hard to the ratchet in most cases, but the ratchet can always bounce the pawl away.

P (parking): used for parking, it is the use of mechanical devices to lock the rotating part of the car, so that the car can not move. When the car needs to stay in a fixed position for a long time, or before leaving the vehicle after stopping, the hand brake should be applied and the paddle lever should be pushed into the "P" position.

It is important to note that the vehicle must not use the P gear until it is completely stopped, otherwise the mechanical parts of the automatic transmission will be damaged.

n (neutral): neutral. With the paddle in "n" gear, the power between the engine and the transmission has been cut off and separated. For a short pause, you can place the paddle lever in this gear and pull the hand brake lever, and take a break with your right foot off the brake pedal.

That is, the N gear of the clubhouse disconnects the power and transmission, and there is no power transmission, while the P gear is locked by a mechanical device to eliminate most of the power to stop the car in place, you suspend the wheels, and the wheels will be idling, but the speed will definitely not be fast.

When towed, the vehicle gets its power from the towing of the rescue vehicle. At this point, the gear selection must be empty, i.e. n-gear. Only in N gear does the gearbox cut off all power delivery.

If it is D gear, it is equivalent to the front car bearing the weight of the towed vehicle, and it has to compete with the engine and gearbox of the towed vehicle. P gear, forced towing after the gearbox is locked, will cause immeasurable damage to the gearbox, there is only N gear. When towing, the drive wheels need to be lifted:

When the automatic transmission car breaks down and needs to be sent to the repair shop, it is best to lift the drive wheels first and regret it before delaying, otherwise the transmission will be damaged. Because when the car breaks down, the oil pump of the automatic transmission does not run, and the various parts lack lubrication and proper cooling. When the drive wheels are dragged on the ground, the transmission is dragged to run together.

Therefore, after dragging a certain distance, the transmission will be damaged. If you can't, you must pay attention to the speed of the trailer should not be too fast, not more than 5km h, and the distance of the trailer should not be too long. It is best to control it within 20 km.

Precautions for trailers: When towing, the front car must be Biqiao Zheng take into account the towing of the vehicle behind, and the principle of "slow and steady" should be adopted for starting and stopping. If you start too hard, it may cause a secondary accident, and the tow rope and the towed vehicle are easy to be injured.

During the towing process, the front vehicle must consider the situation of the rear vehicle.
