What s the deal with the car revving high but not shifting gears

AutomaticThe engine revs very high, and if you don't upshift, it should be the carGearboxIf you have a problem with the computer motherboard, you can go to the store and ask the master to turn down the computer, or replace the gearbox sensor yourself.

Normally, the speed of a new car will be within 4000. Over time, the engine and gears will fatigue, and the gearbox will be sluggish, and the normal speed should be maintained at 3500-4000 rpm without flashing the trip computer or ECU.

Precautions for the speed of the car.

Generally, the first 500km is the initial run-in period.

The speed should not exceed 80kmh and the speed should not exceed 2200rpm. The break-in period of the tires is 300km, because the new tires do not have good friction.

Caution should be exercised.

Medium run-in 500-1000km, the speed can be appropriately increased, but it is recommended not to exceed 100km h, and the speed should not exceed 2500rpm, the appropriate speed is conducive to the run-in of the engine, and the gears should be rotated for running-in.

Hello, the car automatic transmission shift according to the engine speed and the speed of the two to determine the shift, if your speed is not enough, the light speed will not shift, if the speed is enough, the speed is also high or do not shift, that is the gearbox problem, the automatic transmission to get professional maintenance, the general repair shop is not good, particularly precise.

You have driven to 7th gear, what gear do you want to change, your car is only 7th gear at the highest, it has reached the top, it is better to try to stop, see if the speed is low.

The hydraulic system of automatic transmission automobile automatic shift is used to control whether to raise or lower the gear according to the size of the throttle, and the hydraulic reaction takes a certain amount of time, so the automatic transmission car shift response is relatively slow.

The so-called "automatic" refers to the change of each gear of the mechanical transmission with the help of the speed signal system reflecting the engine load to control the actuator of the shift system.

The structural principle of automatic transmission, the transmission ratio selection and shift of the automatic control transmission is carried out automatically, the so-called "automatic" refers to the transformation of each gear of the mechanical transmission is realized by controlling the executive elements of the shift system with the help of the signal system reflecting the engine load and vehicle speed, the driver only needs to manipulate the accelerator pedal to control the speed, and the automatic transmission car will bring the following defects because it is equipped with an automatic transmission

1. The throttle reaction is relatively slow (because after you step on it, it is full of hydraulic systems to control whether to upshift or lower according to the size of the throttle, and the speed of oil pressure is definitely not as direct as that of manual gear).

2. Fuel consumption is high (relative) Although the utilization of the car power of the automatic transmission is higher, it is still a waste of power because of the hydraulic transmission, and it is not as high as the mechanical transmission, so it is very oyster sauce when running at high speed. However, in large cities with more red lights, fuel consumption is poorer.

Summary. Hello, I am happy to answer your car master exclusive technician to answer your car questions sincerely and sincerely for you, and find solutions and methods for you to ask questions. The failure to shift at high rpm is caused by the lock-up phenomenon caused by the presence of fault codes in the transmission computer.

Common problems are due to dirty transmission oil, virtual connection of transmission plugs, or damage to the input and output speed sensors. In this case, you can go to the repair shop and use the diagnostic instrument to read the fault code and data stream to find the cause of the failure. Then replace the relevant accessories on it, I hope mine will help you.

Summary. Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello, the rpm gear is not explained. Vehicle transmission failure, the relevant reasons and treatment methods are as follows: First, the vehicle transmission oil is too dirty or the transmission oil loss is caused by this phenomenon, it is recommended to check the transmission oil first, if there is a problem, you need to replace the new transmission oil. This phenomenon caused by the failure of the valve body inside the second gearbox, this is the need to use the computer to read the failure of the transmission system, according to the further diagnosis and analysis of the fault of Nian Shen, the valve body failure, if there is a problem, it needs to be replaced with a new valve body.

Third, the problem of gearbox shift logic caused by this phenomenon belongs to the gearbox program garbled, in this case, it is necessary to use a special computer to redo the gearbox program upgrade, or match the reset! I hope mine can help you!

1. The engine is the output end of the power, so the speed will be high.

2. Everything from the gearbox to the four wheels is the bearing end of the power, that is, the load.

3. When the gears are coupled together, the entire power chain is linked, and the engine has a load, so the speed is at a certain value.

4. Once the gear is shifted, the power chain is separated, the engine load disappears, the power output of the engine remains unchanged, and the speed will increase instantly.

5. After the gear is changed, the speed will drop immediately.

6. The speed depends on whether it is upshift or downshift, and the change of speed is also different.

The throttle is enlarged, and you can't change gears, you should feel that it can't change gears, and release the throttle when you can't change gears.

The automatic car allowed it to stabilize at around 1800 2000 and the speed shift was normal.

There are two main forms of automatic transmissions used in automobiles. One is a stepless automatic transmission, the other is a continuously variable automatic transmission (CVT), the most commonly used in cars is a mechanical continuously variable transmission, which uses a V-shaped metal transmission belt or transmission chain to transmit torque in the V-shaped groove of the active and passive working wheels. This type of transmission is usually used in smaller vehicles.

Answer: The reason why the automatic transmission cannot upshift may be that the oil pressure in the upper gear of the internal control of the transmission is not enough. The reason for insufficient pressure is that the transmission oil deteriorates and becomes thinner, and the second is that the oil pressure is established by one shaft of the gearbox, and the oil duct may have stolen goods or other reasons to cause insufficient pressure.

The automatic transmission cannot upshift fault check.

Connect the fault diagnostic instrument, query the fault code, if there is a fault code, repair according to the instructions of the fault code; If there is no fault code, the data stream is read to see if the operating characteristics of the relevant sensors have changed and whether the actuator is working properly.

Check the oil level height of the automatic transmission and the quality of the transmission oil, too low the oil level will make the main oil pressure too low, causing the brake clutch to slip, and poor oil quality will also cause slippage or even more serious failure, resulting in the automatic transmission can not be upgraded.

Question: My Elantra automatic transmission ran to 80 and didn't give birth.

Check the spark plugs and cylinder lines, etc. Go and wash the throttle, fuel injector, oxygen sensor, three-way catalytic converter, spark plug and high-voltage line should be replaced, the oil circuit is well cleaned and cleaned, the oil circuit is too dirty.

Question: If the gearbox is broken, how much will it cost to repair?

He can only run to eighty-ninety, ten, and to 100, and he will not go up to it.

Question: What does the person in the repair shop mean when he says the lock is blocked?

How much does this old Elantra automatic transmission cost?

disassembly and assembly man-hours and maintenance man-hours; Materials include the cost of the internal materials of the gearbox and the transmission oil. The biggest impact on automatic transmission maintenance** is the cost of materials inside the gearbox. What is the approximate cost of automatic transmission materials, mainly look at the following points.

1.Depending on the model and transmission model, for example, the previous automatic transmission is generally 4-speed and 5-speed, the internal structure is relatively less complicated, and the parts are relatively low, so the maintenance cost is definitely lower than that of the 7-speed, 8-speed or even 9-speed automatic transmission.

I estimate that it is only about four or five thousand yuan, not necessarily, the ** of the repair plant is different.

The overhaul factory may ask for seven or eight thousand.
