Is it reasonable for a car to change the gearbox twice and ask for a new one

Yes. Changing the gearbox twice has not solved the problem, and the consumer has the right to request the return of the whole vehicle (China's relevant laws and regulations require that the problem is repaired first, and it can only be returned if it is not repaired.) If you haven't changed the gearbox before, the lawsuit is also repaired first, and you can only change it if you can't repair it, and now it has been changed twice, of course, you can ask for a new car)

Hello, consumers can choose to replace or return the goods in five situations: 1. Within 60 days from the seller's purchase invoice or within 3,000 kilometers of mileage, there is steering system failure, braking system failure, body cracking, and fuel leakage; 2. During the validity period of the "Three Guarantees", serious safety performance failures have been repaired twice and still no fault has been eliminated, or new serious safety performance failures have occurred; 3. During the validity period of the "Three Guarantees", the engine and transmission have been replaced twice, or their same main part has been replaced twice and still cannot be used normally; 4. During the validity period of the "Three Guarantees", the same main parts in the steering system, braking system, suspension system, front and rear axles, and body are replaced twice and still cannot be used normally; 5. During the validity period of the "Three Guarantees", if the repair time due to product quality problems exceeds 35 days, or if the same product quality problems are repaired more than 5 times, the consumer can replace it with the three guarantees certificate and car purchase invoice.

The gearbox and the engine are two relatively independent assemblies, and changing gearboxes has no effect on the engine. If it is an automatic transmission, just flash the computer again after replacing it and make a match.

It doesn't matter, as long as the gearbox is the same.

There is no impact, the same is fine, no, the same has an impact.

The gearbox is the transmission mechanism of the rear part of the engine, and the gearbox replacement should be matched, and the replacement of the new assembly will not harm the car. It will not have any impact on the vehicle in the future, and the dismantling and replacement of the assembly can be completed in less than half a day, as long as it is the original modified parts, it will not affect the overall performance of the car.

Under normal circumstances, it has no big impact on the car, but after all, it involves the hoisting of the engine, so it has a certain impact on the value retention rate of second-hand cars in the future, and you must be psychologically prepared.

The gearbox is a transmission mechanism connected to the engine clutch, and replacing the new assembly will not harm the car.

As long as the assembly is an original part, it will not affect the overall performance of the car.

The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic, and the manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations.

No. It is best not to replace the gearbox of the vehicle, because the vehicle has been optimized to match the performance before leaving the factory, after replacing the seven-speed gearbox, although the speed will be faster, it is possible that the torque will be reduced, the load of the engine will increase, and if the life is shortened, if you must change, you can only change the transmission, if it is only solved from the inside of the structure, it is not possible to replace the transmission, and the ** of replacing the transmission is very high, and it is not necessary.

Transmission maintenanceManual transmission is the most commonly seen kind of gearbox, this kind of transmission relies on manual toggle of the gear lever to switch the gear meshing in the transmission, so that the transmission ratio of the car can be changed, to achieve the effect of transmission, manual transmission can freely control the change of gear ratio Generally speaking, old drivers prefer to drive manual transmission cars, because there will be a sense of driving experience, our common manual transmission has 5-speed manual transmission and 6-speed manual transmission.

It should not be affected, and if the transmission problem is serious, you can ask for a replacement of the whole vehicle, and if not, file a claim.

Is there a gap between the construction technology of the 4S and the construction technology of the original factory, I can tell you for sure, there is a big difference, I used to work in the main engine factory, the main engine factory repairs any parts, are based on the new car, after the repair must meet the requirements of the new car, the 4S shop repair is relatively barbaric, the use of equipment is definitely not as sophisticated as the main engine factory, if you can, you should watch the game next to you when you can replace it.

Whether a broken gearbox in a car should be repaired or replaced depends mainly on the extent of damage to the gearbox and the cost of repairs.

Transmissions are present in many cars and can adapt to frequently changing driving conditions, while allowing the engine to work at higher power and lower fuel consumption. The types of transmissions in automobiles are mainly divided into two types, namely manual and automatic. If the owner overtakes frequently and wants the car to be fuel-efficient at this point, then there is an option to install a manual one.

And the automatic transmission can make the driving process easier for car owners. In addition, this kind of transmission needs to be maintained, otherwise the performance will gradually deteriorate, which is not good for the owner.

Look at what reason it has been replaced, such as the manufacturer's recall, etc., the basic impact is relatively small, such as due to the accident, it is still relatively large, if the personal use is improper to replace the original factory, there is also an impact.

It has an impact, don't take the initiative to tell you to change it when you sell the car.

It is divided into two types: manual and automatic, manual transmission.

It is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; And the automatic transmission.

The AT is made of a hydraulic torque converter.

Planetary gears and hydraulic control systems are composed to achieve variable speed and torque through hydraulic transmission and gear combination. There is no formalities for replacing the gearbox in the car, you just need to pay the repair shop to replace it. Replacing the engine and girder requires procedures.

What are the procedures for changing the transmission of a car? My understanding is that there is no need for anything, because the gearbox is a normal replacement of wearing parts, it cannot be said to be a wearing part, it is a normal replacement of accessories, alas, this Sun Xi does not need to go to the vehicle management office.

For the record, what is not used um, if the gearbox is broken, it can be replaced normally. Replacing any of the assemblies will not have an effect. Cars are assembled from assemblies.

In fact, the car is composed of several large modules, just like building blocks. In the process of building, if you find that there is a problem with some building blocks, you can replace it in time. The gearbox is one of the three major parts of a car, and it is called the powertrain of the car when combined with the engine.

The two are simply connected together with a few screws. The type and scope of consumable parts and their quality assurance period shall be clearly indicated by the manufacturer on the three-guarantee certificate. The scope of the types of consumable parts indicated by the manufacturer shall comply with the relevant national standards or regulations, and the specific requirements shall be separately stipulated by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China.

According to the country's three guarantees, you have no right to request a return of the car, only the gearbox can not be used normally if the gearbox is replaced more than twice in a row can be required to change or return the car. And the return and exchange will cause you more losses, because the return of the car will not compensate you for the purchase tax.

and the loss of insurance, this needs to be borne by yourself, so returning the car is not the best choice for you.

To replace the gearbox, the first thing to consider is the problem of quality assurance, which is the core component. If you need to replace the first choice 4S shop warranty without shouting rough worries, the cost is high, and the integrity is high and the technology is strong. Stool.

If the input code is manually replaced, then the clutch must be stepped on to the end, which can also avoid some damage, and should also choose different lubricating oils according to the different temperature around the delay.

Be sure to pay attention to changing the original gearbox, and be sure to change the best gearbox, don't choose some bad quality Zheng Lu on the call, avoid and avoid causing potential safety hazards.

No.

The new car replacement transmission is replaced with a new assembly will not harm the car, nor will it have any impact on the vehicle in the future, as long as it is the original modified parts, it will not affect the overall performance of the car. However, after all, it involves the hoisting of the engine, so it has a certain impact on the value retention rate of second-hand cars in the future.

Precautions for replacing the gearbox in a new car.

Before installing the transmission cover, check whether there are any missing parts in the site, whether the shafts and fixed gears have axial movement, whether the paper pads are intact, and whether the pairs of meshing gears are meshed within all tooth widths; Toggle the sliding gear by hand to see if it can move axially to a full-tooth wide mesh; Turn the first axis by hand and try each gear separately, all of which should be able to rotate flexibly and smoothly without jamming. Add the appropriate amount of lubricating oil to the gearbox body according to the regulations.

The assembly sequence is opposite to the disassembly order, that is, the parts that are removed are installed first, so that all parts are installed in the original position, and the fitting parts should be rotated often during the installation process, and the direction of the oil seal should not be damaged.

Summary. Hello, dear, I am happy to answer for you: there will be no sequelae after the car changes the gearbox:

1. The gearbox is the transmission mechanism of the rear part of the engine, and the replacement is a new assembly, which will not cause any harm to the car and will not have any impact on the future of the vehicle; 2. The disassembled assembly can be completed in less than half a day, as long as it is the original factory improvement parts, it will not affect the overall performance of the vehicle; 3. The gearbox mainly refers to the gearbox of the car, which is divided into two types: manual and automatic, and the manual gearbox is mainly composed of gears and shafts, and torque changes are generated through different gear combinations. Generally speaking, the replacement of the gearbox assembly has little impact on the car, but after all, it involves the hoisting of the engine, so the value retention rate of the second-hand car in the future has a certain impact, and we must be psychologically prepared. After the vehicle replaces the transmission assembly, there is generally no sequelae, the owner does not need to worry too much, and the replacement of the transmission assembly will not have any impact on the engine at the same time.

Does changing gearboxes help with speed?

Can I get to more than 100 yards within a few hours of a gearbox change?

Replacing the gearbox has little to do with speeding up, it needs to be replaced because your previous gearbox was damaged.

Dear, the new gearbox is not suitable for driving so fast, and the new gearbox also needs a short break-in period.
