Geely MK is a Chinese representative of the C class, which is a development of the Geely Automobile companies. Behind last years The Chinese auto industry has made a real breakthrough in the automotive industry. One of the main components of the popularity of this model is the design - the appearance of the car is not typical for an eastern manufacturer and is more reminiscent of an “American”. It’s not worth comparing this car with the Americans, Japanese or Koreans, since they are higher in build quality and components, but this model has one parameter in which it surpasses all its competitors, and this is its price, and this parameter has always been one of the main ones when choosing a car. And, here’s how the low cost of the car affected its reliability, and what you should pay attention to when choosing a Geely MK with a mileage of secondary market, now let's try to find out.

A little history:

In the domestic Chinese market, the premiere of Gili MK took place in 2006, but in the CIS this model appeared only in mid-2008. The basis for the development of the car was the first generation of Toyota Yaris, and Toyota engines are also used in the car. Geely previously bought these engines from Tianjin Industrial (FAW), which holds the Toyota license. In January 2010 at the plant car company"Derways" in the city of Cherkessk (Russia), the production of cars for the CIS markets was launched. Before this, Geely MKs were supplied to car dealerships directly from China. In 2011 Geely company carried out a rebranding, as a result, the car was named Englon MK, and the MK Cross was renamed Englon Jinying cross. The rebranding was carried out in connection with a new marketing strategy aimed at updating and raising the brand image. In 2015, the Geely MK was replaced by the GC6, which is a deep restyling.

Weaknesses and disadvantages of Geely MK with mileage

Metal, like paintwork, very thin, because of this, chips and dents appear even from a small pebble flying out from under the wheels of oncoming traffic. The body is weakly resistant to aggressive influences environment, which is why rust appears on the car body after a couple of years of use. Corrosion appears most quickly on the underside of the car (additional treatment with anti-corrosion agents is required) and in places where the paint is chipped. Also, traces of rust can be found on: the front doors (under the seal), the hood and the gas tank cap (in the lock area). The protective glass of fog lights often cracks when used in cold and damp weather.

Engines

Geely MK was equipped only with gasoline power units - 1.5 (94 hp), 1.6 (107 hp). The most common engine in the CIS is a 1.5 liter unit, which was assembled under a Toyota license (a copy of the 5A-FE engine from). If we talk about its reliability, then, in general, the motor is not bad, but a couple weak points in it, nevertheless, it was revealed. The first thing you need to pay attention to is the timing belt. According to the regulations, it does not require replacement until 60,000 km, but, as operating experience has shown, cracks appear on it after 40,000 km, and it may also be missing a couple of teeth. I don’t think it’s worth explaining what consequences this could lead to. For those who like to carry out repairs in their garage, it is worth considering the fact that to replace the timing belt you will have to remove the right engine mount.

It’s not uncommon for owners to encounter trouble when an engine that is not warmed up starts to stall, fortunately, to solve the problem you can do without a trip to the service center - you need to change the spark plugs, high voltage wires or ignition coils. If these manipulations do not give a positive result, you will have to adjust the valves. To perform this procedure, you should contact an experienced specialist, since incorrect adjustment of the valves can lead to their “squeezing” after 40-60 thousand kilometers and subsequent burnout. High-voltage wires must be removed very carefully, as there is a high risk of their breakage.

On cars with mileage over 50,000 km, coolant leaks appear through the throttle heating gasket. If the defect is not corrected in a timely manner, this may lead to premature exit regulator failure idle move. The main signal about a malfunction of the regulator will be: difficult starting, the engine stalls immediately after setting and starts only when you press the gas pedal. A new regulator will cost 20 USD, but you can save a little by installing an analogue from a Chevrolet Niva (8-10 USD).

In the warm season, it is necessary to carefully monitor the engine temperature; most often, the engine overheats when driving for a long time at a speed of 80-100 km per hour with the air conditioning turned on. The main reason is the cooling fan not turning on, poor contact at the wiring terminals and late opening of the thermostat. The ability to monitor engine temperature and prevent it from overheating is complicated by the fact that the temperature sensor may produce incorrect data. If it is not possible to warm up the engine to operating temperature for a long time, the problem is most likely due to the thermostat sticking in the open position.

On most copies, at a mileage of 80-120 thousand km, the cylinder head gasket has to be changed, the reason is the cylinder head gasket burns out. At the same mileage the pump needs to be replaced. The cooling radiator is susceptible to corrosion. A signal that there is a problem will be the appearance of red spots in the expansion tank. With the arrival of cold weather, the cooling radiator may begin to leak at the junction of plastic and metal. At a mileage of 80-100 thousand km, it becomes necessary to replace the front crankshaft oil seal (oil leaks appear). Once every 60-80 thousand km the oil pressure sensor needs to be replaced. Engine and gearbox mounts have a slightly shorter service life (40-60 thousand km). Many owners complain about high fuel consumption, mixed cycle 8-10 thousand km, and this is much more than the manufacturer promised.

Transmission

The Geely MK was equipped only with a five-speed manual transmission. Transmission diagnostics must be treated with extreme care. The main ailment that owners have to deal with is the fragility of the bearings of the primary and secondary shafts. Most often, owners of cars with a mileage of 50-70 thousand km contact the service with complaints about extraneous noise in the transmission. You will have to spend 100-150 USD to fix the problem. Axle shaft seals are also not famous for their durability; as a rule, oil leaks appear after 30-40 thousand kilometers. At a mileage of 60-70 thousand km, the clutch master cylinder needs to be replaced. To save a little, the cylinder can be repaired using a special repair kit. When using low-quality oil, with the onset of cold weather, difficulties with shifting gears appear. With careful operation, the clutch can last 80-100 thousand km (a set of a new clutch with a release bearing will cost 40-60 USD).

Features and disadvantages of the Gili MK chassis

The Geely MK uses the standard suspension for this class of car: MacPherson strut at the front, beam at the rear. As for the reliability of most chassis elements, the situation here is not so optimistic. Most often, replacement of stabilizer struts is required; for careless drivers, they last less than 10,000 km; with careful operation they can last 15-20 thousand km; bushings up to 40,000 km. Shock absorbers last 50-60 thousand km, but there are often cases when they had to be changed even after 30,000 km, fortunately their price is not too high up to 50 USD. PC. Front wheel bearings, levers and ball joints can please you with a mileage of 70-80 thousand km. CV joints can last up to 100,000 km. In order to be less likely to encounter chassis repairs, many owners, when selecting spare parts, give preference to interchangeable parts from different models Toyota.

Play in the steering rack occurs even on almost new cars, the reason lies in poor quality assembly of the unit, fortunately, to eliminate the defect it is enough to tighten it. The service life of the rack differs little from a similar part from most Japanese and Korean manufacturers (100-150 thousand km). Buying a new rack will cost 150-250 USD. Steering ends require replacement every 50-60 thousand km, rods every 70-80 thousand km. There are also problems with braking system, the main one is corrosion of the brake cylinder piston, which leads to brake jamming. Also, the rear cylinders require special attention; there have been cases when brake fluid leaks appeared on them.

Salon

The interior of the Gili MK cannot boast of the quality of assembly and materials, but thanks to the use of hard plastic, crickets feel right at home here. If you hear rattling noises from the steering wheel while driving, you need to check the degree of tightening of the bolts holding the airbag (they loosen over time). With intensive use, the front seats can wear out within a year, taking with them heating elements. If you neglect replacement, it could end in a fire. Due to poor quality sizing windshield and rubber plugs constantly falling off on the bottom, water appears under the driver's and front passenger's carpet over time. Also, after heavy rain, a puddle may appear in the trunk, the reason is poor-quality seals of the rear lights and rear shock absorber supports.

As for electrics, most often, unpleasant surprises come from the heated rear window, mirrors and climate system. Many owners complain that the air conditioner does not cope with its duties even in cool weather. At a mileage of 80-100 thousand km, freon leaks appear, and at the same mileage the air conditioning compressor may jam. At the most inopportune moment, the stove fan may stop turning on, the reason being the failure of the speed controller relay. After 100,000 km, problems begin with the voltage regulator (repair or replacement of the generator is required), as a result of which the battery stops charging. Due to a failure of the electric motor driver board chip, the instrument panel backlight stops working.

Result:

Despite significant progress in the automotive industry, the Chinese auto industry still does not reach the level of Korean and Japanese manufacturers, and Geely MK is no exception. This car cannot be called bad, since the short service life of some parts is justified by the low cost of the car and the low cost of repairs and maintenance.

If you are the owner of this car model, please describe the problems that you encountered while using the car. Perhaps your review will help the readers of our site when choosing a car.

Gearbox whining is a fairly common occurrence. How to correctly diagnose problems and decide on the need for repairs.

Oil: maybe this is the reason?

There are several reasons why a transmission starts to howl. The first, most common, is the oil level in the box. Many motorists do not attach importance to the need to monitor the oil level in the gearbox. This leads to oil starvation mainly in the fifth gear, which is higher than the rest. Due to the lack of oil, the bearings begin to overheat and fail. This is accompanied by a high-pitched howl that occurs when driving in fifth gear. This disease is treated by overfilling 100 - 200 grams transmission oil above the level with constant monitoring.

Some may say that overfilling the oil will cause it to leak through the seal joints. To prevent this from happening, you must first clean the breather, and secondly, pour oil in parts, gradually. For example, at first 100 grams, and after a while, if there is no leakage, so much more. You can also add a second oil seal to the gearbox rocker.

The next, no less common reason for the sound of the gearbox is the poor quality of the gear oil poured into the gearbox or incorrectly selected. If we talk about domestic cars, then, for example, the use of oil of the APIGL-5 category in the gearbox of front-wheel drive VAZs leads to rapid wear of the synchronizers, which will cause gearbox noise when switching. Therefore, it is mandatory to use an APIGL-4 class transmission. Domestic oils This classification is quite difficult to find, so you have to use lubricants from foreign manufacturers. But their use can significantly extend the life of the gearbox, avoiding various sounds when driving.

In addition, insufficient or excessive viscosity of the oil used also affects the wear of box parts and the presence of sound during its operation. For example, very thick oil with a viscosity of 85W-90 creates a strong film, protecting gears from wear, but at the same time it makes it difficult for lubricant to reach some gearbox parts, which may suffer from oil starvation, causing premature failure. It will also be difficult to change gears due to the need for synchronizers to squeeze out excess oil, which again will lead to rapid wear of parts. The first sign is strongly thick oil There will be a whine when it is cold and it will disappear when the unit is warm.

Too thin an oil will cause the opposite effect, in which the oil film will break off when hot, accelerating the wear of gearbox parts, which will again be accompanied by howling and humming.

You should be extremely careful when choosing gear oil according to the recommendations of the manufacturer and experienced servicemen.

Oil additives: is it possible to do without repairs?

If changing the oil does not help, the gearbox howls, then it is necessary to repair the unit. Many people can talk about adding additives, but this does not help in 80 percent of cases. According to reviews from many motorists, adding additives can only temporarily or not completely muffle the sound, but will not completely solve the problem.

Chemically active substances contained in revitalizant additives form a cermet layer on the surface of worn gears and bearings, which, according to the manufacturer, restores the geometry of the parts and compensates for wear. Of course, if the howl of the gearbox is barely noticeable, it has just begun, then adding, for example, Hado, may well delay the problem with repairing the gearbox. But it may not help if the problem is already old and the wear on the unit components is significant. Then repairs are definitely needed.

Diagnostics and repair

As for transmission repair, it is very important to first carry out a correct diagnosis of a possible malfunction of the unit, try to determine why the gearbox makes a howling noise without removing the unit. Usually the box does not howl in all modes, but at some speeds. If a howl accompanies movement in 1st, 2nd, 3rd gears, then this usually indicates problems with the bearing connecting the primary and secondary shafts, or more precisely, its wear. The only solution is to replace it. But there is a small nuance - if the bearing is a needle bearing without a cage, then simply replacing the needles may not help. This will require replacement of the shafts. And this is already a serious repair.

It is also possible that there may be a howling noise when the working pair of gears located on the primary and secondary shafts of these gears wear out. Or due to poor quality factory processing and installation after repair. One of characteristic features gear wear is a howl under load and its reduction in the absence of traction. A worn bearing will make noise regardless of whether there is a load or not. But you can determine the exact reasons only by disassembling the gearbox and showing it to a specialist if the repair is done by yourself.

If there is a whine in 5th gear, the first thing that needs to be done is to check and add oil to the unit if necessary, as discussed earlier. But if this does not help, then most likely the fifth gear gear needs to be replaced. This is determined by opening the box. Preliminarily, by the sound at high speed, you can determine the cause - if there is an obvious whine, the gear is worn out; if there is a squeaking sound over 100 km/h, it is most likely the bearing.

If the gearbox of front-wheel drive cars howls in all gears, then there is a high probability of wear on the input shaft bearing. But replacing it often does not lead to a positive result, so changing it in the presence of minor howling is not recommended.

Or maybe it's not a box at all?

When diagnosing a gearbox, be sure to carefully consider the fact that if there is a constantly increasing howl in all gears, it may not be only the gearbox that is to blame for the origin of the sounds. On models with a classic drive, the source of the whine may be the gearbox rear axle, having a bevel hypoid gear. If the gear teeth are worn out or there is significant play in the bearings, a howl will accompany all driving modes. Similar symptoms also accompany four wheel drive vehicle if the front axle is faulty. The sound will come from the center of the cabin and be observed under load.

Summing up

When repairing a singing gearbox, it is important to remember the poor quality of manufactured units and spare parts. It does not indicate that the purchased spare parts or units are new - they may also have defects. Sometimes, with minor noise in the gearbox, it is easier to turn up the volume of the radio in the cabin than to try to eliminate the cricket by going through the box several times.

Good luck on the roads!

Geely MK / Cross. Reduced coolant level

Scroll possible malfunctions	Diagnostics	Elimination methods
Damage to the radiator, expansion tank, hoses, loosening of their fit on the pipes	Inspection. The tightness of radiators (engine and heater) is checked in a bath of water with compressed air under a pressure of 1 bar	Replace damaged parts
Liquid leakage through the coolant pump seal	Inspection	Replace the pump
The cylinder head gasket is damaged. Defective block or cylinder head	There is an emulsion with a whitish tint on the oil level indicator. There may be abundant white smoke from the muffler and oil stains on the surface of the coolant (in the expansion tank). Coolant leaks on the outer surface of the engine	Replace damaged parts. Do not use water in the cooling system, fill with coolant appropriate to the climatic conditions

Reasons for the drop in level coolant in the expansion tank (decrease in antifreeze level)

Changing the coolant level is quite natural. When the engine is cold, the level decreases, and when the engine is warm, the level increases. Similarly, the level changes depending on the ambient air temperature. IN winter time, the volume becomes smaller in the expansion tank, and in the summer it becomes larger. But what if you begin to notice a constant decrease in the volume of liquid in the tank. There are other reasons for the decrease in antifreeze levels, which are caused by the malfunction of certain components in the cooling system.

The first thing a car owner should do to find out the reasons is to determine the location of the leak. To do this, when you park your car in a garage or parking lot overnight, place a clean white piece of cardboard under the hood. In the morning, look carefully to see if there is liquid on the paper and in what area. Typically, the leak occurs either under the radiator or under the engine, where there is a pump (water pump) that pumps antifreeze through the system.

Very often, leaks are caused by loose hose clamps. Use a flashlight to inspect the engine compartment and, if possible, drive the car onto an overpass or pit to get a good inspection under the hood. Check where the clamp holds the hose. If the reason is in the clamps, then you will quickly find a constantly damp place from where antifreeze leaks. In this case, you should replace the clamp with a new one and check if there is any leakage after this. If all the clamps are dry and the decrease in the antifreeze level continues, then you should check the pump. Often, this pump that pumps antifreeze through the system fails, especially if it is of poor quality. The pump is replaced every 50-60 thousand km, although many car owners wait until it breaks down and only then contact a car service center. You can notice a pump malfunction by the following signs:
- the area around the pump and drive belt is constantly wet;
- the stove in the cabin began to heat poorly;
- remove drive belt and try to turn the pulley. A loose pulley is a sign of a malfunction;
- the appearance of a clearly visible gap in the pulley drive is the most likely sign of a pump malfunction or that the pump will soon fail.
A characteristic sign that the pump has already failed is, in addition to antifreeze leakage, a constant knocking sound while the engine is running. The source of the knocking is faulty pump bearings.

If you do not notice all of the above signs, check the condition of the radiator. Indirect signs of a radiator failure are:
- antifreeze stains under the hood in the radiator area;
- constant fogging of the windshield;
- in the front passenger area there is a constant appearance of oil stains on the floor.
If these signs are detected, repairs at a service station are required.

A decrease in antifreeze level can occur if the cylinder head gasket is broken. If this part breaks, coolant begins to enter the oil channels. A characteristic sign is the appearance of white smoke from exhaust pipe and the appearance of transparent bubbles on the oil dipstick. If these signs are detected, you should contact a car service center and do not operate the car. When antifreeze gets into the oil, it reduces its lubricating properties, which over time can cause the engine to overheat and break down.

Evaporation of antifreeze and other causes of its leakage

Antifreeze is a substance used in the cooling system of vehicles, characterized by a high boiling point and low freezing point. Now there are three main colors - red, green and blue.

The basis of this composition is a glycol-water mixture, which determines the property of antifreeze not to freeze at subzero temperatures. Among domestic manufacturers, the most common are ethylene glycol-based products. However, an aqueous solution of such a substance is quite aggressive towards some materials of the car cooling system.

To prevent damage to parts, this substance also contains various additives: anti-corrosion, stabilizing, anti-foaming.

Common cooling system failure

The most common breakdown of a car's cooling system is a decrease in antifreeze levels. Signs of this problem are:

A large amount of steam coming out from under the hood;
White smoke what comes out of the car muffler;
The stove reduces the air temperature in the cabin, rather than increasing it;
Dashboard signals engine overheating;
The thermometer in the car has reached its maximum value.
Sometimes even several signs appear at the same time, in which case the car must be turned off immediately and provided with maintenance at a service station.

Why does the antifreeze level decrease?

A decrease in the level of antifreeze in the coolant reservoir is a fairly common phenomenon nowadays. This can happen for several reasons:

During the cold season, the coolant tends to decrease in volume. Therefore, in winter this substance should be added more often than at other times.

Liquid passes into cracks and crevices of the tank or its lid. It can be quite difficult to detect such problems, because cracks along appearance may resemble normal scratches. However, this may be sufficient for a slight loss of antifreeze from the tank.
leaves the tank

Depressurization of various connections of the cooling system or damage to its tubes and hoses. Leaks also occur with the thermostat gasket.
Various radiator breakdowns can also cause a decrease in coolant level.
radiator leaking

Another reason for antifreeze leaving the vehicle system is its evaporation. Any coolant contains water, which, even despite the tightness of the cooling system, gradually evaporates from it. Experts note that a decrease in the fluid level in such an automobile system by about 200 grams between two adjacent scheduled maintenance is the norm.

Thus, even in the absence of any damage, antifreeze gradually evaporates from the car’s cooling system, although this occurs in very small volumes.

If the coolant leaves quickly enough, the reason lies not in evaporation, but in some other problem, so you should immediately go to a service station for professional help.

If it is not possible to use the services of a car service when the antifreeze “leaves”, you can try to determine the cause of this problem yourself.

First of all, you should check the oil with the engine not running - remove the dipstick and carefully inspect it for traces of any liquid other than oil.

After this, start the engine and leave it running until the fan comes on. In this case, it is necessary to monitor the cooling system to see if drops of liquid appear somewhere, especially at the joints and hoses. There is a small chance that the problem may lie in the radiator, but it is very difficult to determine this on your own.

It would also be useful to check the tightness of the tank closure. Usually in this case, light vapor will be noticeable coming out from under the hood, and characteristic traces of liquid evaporation will remain on the tank.

The gearbox is one of the most complex mechanisms in the entire car. Only the engine can compete with it in terms of design complexity. This is precisely the reason why it is often even more expensive to repair a box. power unit. To understand all the features of this process, it is enough to look at the diagrams of the gearbox from the inside - this will give an understanding of the high complexity and manufacturability of all the mechanisms built inside the housing. Repairs must be carried out exclusively by professionals, otherwise the unit will not be able to last a sufficient amount of time. You need to understand that the reliability of the car’s ride, the ease of its operation and the physical ability to go on long journeys without fear of terrible breakdowns depend on the quality of the box.

The gearbox can show a variety of troubles during operation, but one of the most common manifestations of a breakdown is a hum in the gearbox. The hum can be of varying intensity, tone and strength. You may barely notice it, and sometimes the hum is so loud that accelerating the car to high speed or revving the engine to high speed I just don't want to. Sometimes such a hum turns out to be only evidence of some technological features boxes. Sometimes it occurs after repairs, when the parts do not fully fit together. In this case, this is not critical, but the hum can only be removed through repeated repairs. Let's look at the reasons that make you feel increasing discomfort when driving in a car and feel unpleasant sounds from under the hood.

Automatic transmission - the hum is definitely not good

If you have an automatic transmission, CVT or robotic mechanics with automatic switching, the hum definitely does not bode well for you. At any service, disassembling and reassembling your box alone will cost incredible amounts of money. Today you will not be too pleased with the prices for spare parts. Sometimes it is better to listen to the hum than to hear the price it takes to eliminate it. Use the help of specialists to diagnose the gearbox, but remember that full diagnostics of your machine is only possible if the box is disassembled. Most common reasons The hum of automatic transmissions is as follows:

• in a regular vending machine or robotic box one of the elements may be erased main couple, giving backlash in work;
• the gears do not touch each other in normal modes, excessive friction of the mechanisms in the gearbox occurs;
• for a variator, a hum almost certainly means death or the need for major repairs - stretching of the main working mechanisms is not so rare;
• the box can also hum due to poor fastening of the axle shafts, which causes play at the joints and a rather strong hum;
• Bearings that have failed often hum; they will definitely show themselves in the near future;
• worn teeth on the drive gear or shaft will indicate the presence of backlash and constant hum in one or more gears.

Often, along with the hum, some other troubles with the gearbox begin to occur. For example, the transmission begins to throw out one of the gears after you release the gas pedal to slow down. The gear forks may be to blame for this, but it all depends on the gearbox, its type, design and other features. If for a manual transmission this problem is quite easy to overcome, then for an automatic transmission, dropping gears in unauthorized mode means the impossibility of operating the car. Otherwise, traveling in such a car will be unsafe. So always watch out for sounds coming from the machine and contact service center to eliminate them.

Manual transmissions are noisy for many reasons.

In mechanics, the reasons for the occurrence of hum in gearboxes are no less than in automatic transmissions. It must be remembered that manual transmission Quite gentle, likes moderate use and no sudden movements. This even applies to sports boxes, which are most protected from damage when sports modes trips. However, such boxes are considered more reliable and durable than automatic types. This is a rather controversial truth, because there are different machines and there are different manual gearboxes. Many car enthusiasts prefer mechanics due to the fairly low cost of restoration. Although, it depends on what caused the hum in the gearbox:

• wear or unequal replacement of elements of the main pair - the hum can continue for a long time without negative consequences, but, in the end, the box will fail;
• the drive bearings are worn out - they will hum for several weeks of active use and fall apart, causing not very pleasant consequences;
• gears - if the hum is heard only in one gear, the culprit of such trouble is the gear of this particular gear;
• poor-quality assembly of the box is often the reason why a hum occurs due to a mismatch between the shaft and the gears;
• poor operation of the gear shift mechanism leads to inaccurate and uneven shifts;
• Individual and unexpected problems often arise in mechanical transmissions, which are diagnosed only after disassembly.

Such troubles are possible in every car. Certainly, domestic cars become more frequent visitors to professional service stations. But often expensive, technologically advanced foreign cars come to stations with questions about gearbox noise. It should be noted that in most cases, high-end cars do not present such problems. They are made of the highest quality and can last for many years without issue. But in some cases, it is not the engineer or assembler at the factory who is responsible for the box failure, but the driver himself.

What to do if a hum begins to come from the box?

The best solution in this situation is to immediately turn to a good station Maintenance to obtain information about the nature of this hum. If a specialist, after diagnostics, says that wear has begun on the main pair or other gears of the box mechanism, you can safely drive for a few more weeks, collecting money for renovation work. But remember that wear on the main pair shaft sometimes has a negative impact on the condition of all gearbox mechanisms. So you may well get the situation to the point where your box will have to be sent to major renovation or even a replacement. The box repair algorithm is as follows:

• bring the car for a quality service with a sufficiently large number of specialists and good equipment for repairs;
• To begin, order disassembly and complete detailed diagnostics of the gearbox to identify problems;
• If you identify a problem, estimate the cost of restoring the car and potentially repairing your box;
• make a decision based on the proposed facts and provided information from specialists;
• order gearbox repairs from those professionals whom you completely trust - poor quality of repairs cannot be tolerated;
• install only original expensive parts inside the box, as they can last a long time and have a guarantee.

One of the most expensive processes in transmission repair is disassembly and diagnostics. Then everything is done at affordable service station prices. You need to keep this in mind when choosing parts for your transmission. It is best to use original factory spare parts to completely eliminate troubles in the near future. This way you will save on subsequent repairs and can easily complete the necessary tasks in one process of disassembling the box. You should not skimp on parts and the quality of work performed, as this may negatively affect the operation of the unit. We suggest considering the reasons for the hum in the box, which experts talk about:

Let's sum it up

Many motorists are faced with such a problem as gearbox noise. It could be an automatic or manual transmission, any version of a modern robot or such a fashionable CVT. There are dozens of diseases technical units and units that may negatively affect this part of your car. Therefore, you should pay Special attention on the features that the gearbox provides you during operation. If you simply miss the moment when bearings or other parts begin to hum, you may soon find yourself on the side of the road without the ability to move in your car.

There are many types of motorists. Some want perfect job of their vehicle, others are content with the fact that as long as the car is driving, there is no need to repair it. But most owners Vehicle they want the main components of the machine to work well and efficiently. Therefore, do not neglect good diagnostics to find out which part of the box is causing the unpleasant hum. Most likely, after such diagnostics, you will want to restore the node. Has your car ever had problems with the gearbox that caused an unpleasant hum?
