How to reduce transmission noise?

Noise generated while driving at checkpoints is a problem faced by many motorists. Some just get used to this fact, because the car can go - it means that everything is in order with it. Others put the car for repair and go through all the components of the transmission to identify the failed part and replace it.

But lately, manufacturers of automotive consumables have come up with various innovations to make life easier for motorists. In this case, we are talking about automotive additives designed to reduce the level of extraneous sounds in the gearbox. The use of this consumable will be ideal for those who do not want to disassemble the gearbox, because this business is not so simple.

It is also worth noting that the noise during the operation of the gearbox can occur even on new cars. In some cases, third-party sounds may disappear over time when elements transmission system"Get used to" each other. In this case, the use of additional additives can correct the situation.

In addition, the use of additional substances may be advisable if the parts of the power unit begin to fail or grind off. Of course, if the gearbox elements are completely out of order, the use of additives does not make sense.... Further, the properties and characteristics of the most popular types of revitalizants (additives) available on the domestic car market will be described.

Revitalizant Xado

This substance is intended to restore gearbox gears, bearings and other units of the unit, as well as to protect them from increased wear. The essence of using this revitalizant is that it forms an additional metal coating over the gearbox elements. In addition, according to the manufacturer, Xado can also restore the geometry of damaged transmission system components.

Concerning additional benefits Xado:

elimination of potholes and scratches on the working surfaces of the unit;
decrease in the level of additional sounds by 10 times;
promotes more optimal operation of synchronizers;
allows you to reduce the consumption of gasoline consumed, especially when it comes to all-wheel drive vehicles;
allows you to operate the gearbox even if there is a transmission fluid leak in it.

Technical characteristics of the substance:

microhardness index is 750 kg / mm2;
resistance to corrosion.

As for the use, as mentioned above, the revitalizants should be poured into the oil filling hole in the gearbox. The filling volume of the element in the gearbox fluctuates depending on the volume of the oil system. If your volume does not exceed 2 liters, then one tube of the additive will be enough. If the volume reaches 5 liters - you need to fill in two tubes, if more than five - then you need to fill the system with three tubes. It is necessary to fill in the additive when the car engine warms up to working temperature.

MosTwo Ultra

MosTwo Ultra is a revitalizant Russian production, which has proven itself in front of domestic motorists. The information provided below is official and does not carry any advertising. The essence of using this additive is:

the formation of a protective film with a low coefficient of friction on the surface of the friction elements of the gearbox;
reducing the level of friction, eliminating defects on the surface of parts, as well as restoring the nodes of the transmission system;
reducing the noise level in the gearbox, as well as making it easier to shift the gear lever;
increasing the service life of the gearbox up to five times;
an increase in the resource of the gearbox service even if the vehicle is operated under maximum loads;
reducing the level of third-party vibrations;
raising performance characteristics elements of the unit.

According to the manufacturer of the substance, key feature the use of additives is the possibility of their use without disassembling the power unit. Of course, this only makes sense if there are no mechanical damages in the gearbox assemblies. In addition, this revitalizant can be used with absolutely all types of gear oils.

1Stage Transmission

This revitalizant is the third generation product of the Xado company. Like other additives for gearboxes, 1Stage guarantees the consumer a refurbishment of gearbox assemblies, a decrease in the level of wear, as well as an increase in the service life of unit parts. In particular, we are talking about mechanical and robotic units. The use of this additive in automatic gearboxes as well as in robotic boxes gears with two "wet" clutches.

As a result of the use of advanced technologies in the production of additives, 1Stage can independently regulate the appearance of a protective film on the working surfaces of the unit. In addition to the main advantages, 1Stage allows you to:

to form a cermet film with reliable protective properties on the surfaces of the main components of the gearbox;
reduce the level of third-party sounds and vibration in the unit;
increase the level of clarity when shifting the gearshift lever;
reduce gasoline consumption;
to protect power unit even if all the oil flows out of it;

The additive must be poured into the transmission fluid fill hole or the dipstick hole when the vehicle is at operating temperature. For the volume of the transmission system of 3 liters, it will be enough to pour one tube of the substance.

Revitalizant Getriebeoil-Additiv

Getriebeoil-Additiv Antiwear is manufactured by LiquiMoly, one of the leading manufacturers of engine and gear oils. The additive is based on molybdenum disulfide, and its purpose is to operate vehicles with manual transmission.

As the manufacturer assures the owners of vehicles, due to a decrease in the temperature in the friction zone of the components of the gearbox, the gearbox is much quieter. In addition, the work of the teeth is greatly improved, which makes it easier to shift the gearshift lever.

Since the revitalizant reduces the level of friction, its operation is unacceptable in automatic gearboxes. One tube of the substance is designed for 2 liters of gear oil, but it is also worth considering the regular load of the gearbox.

Nanoprotec MAX

Revitalizant for Nanoprotec transmission fluid is intended for use in manual transmissions. The additive processes the parts of the aggregate of any type of transport - both cars and trucks. According to the manufacturer, it is optimal for both Russian-made and foreign cars.

As for the benefits:

the substance forms an oxide film in the gearbox units with a low friction index, which makes it possible to reduce the appearance of new noise;
improves the ratio useful action motor due to the low coefficient of friction;
reduction in gasoline consumption due to the reduced resistance of the gearbox components.

Due to its characteristics, Nanoprotec makes it possible to increase the service life of the checkpoint as a whole. The film formed on the surfaces of the unit components is resistant to increased loads and reduced friction values. This means that the gearbox components that have been treated with the revitalizant will wear out much more slowly, which makes it possible to increase their service life.

EX 120

Revitalizant EX 120 is intended for use in transmission mechanical systems auto. EX 120 reduces the level of wear and tear, as well as restores damaged units of the unit, increasing its service life.

The manufacturer assures its customers that EX 120 contains 20% more active revitalizing components, which makes it possible to restore damaged gearbox parts much more efficiently. This additive, like any other for the gearbox, forms a protective film on the surface of the assembly elements (bearings, synchronizers and shafts) and restores the geometry of these components. Of course, if necessary. It can be used in both mechanical and robotic units.

Benefits guaranteed by the manufacturer:

improves the clarity of shifting the gear lever;
helps to reduce fuel consumption, in particular when it comes to all-wheel drive vehicles;
eliminates scratches and irregularities on the working surfaces of the components of the power unit;
as mentioned above - the additive reduces the level of external sounds and vibrations in the gearbox;
synchronizers will work more clearly.

Revitalizant

This additive was developed by Xado engineers. Therefore, the benefits and characteristics of this substance are identical to those of the Xado additives. Revitalizant was created in order to restore failing gearbox parts and protect them from increased wear as a result of long-term use of the car.

Unlike traditional Xado, Revitalizant is operated in a slightly different way:

The substance must be poured into the hole where the transmission fluid is poured. It is enough to add 3 ml of revitalizant for one liter of oil. This will be the first stage of processing the checkpoint, a total of three.
The second time it is necessary to add the substance when the car has traveled at least 4 thousand kilometers or every 150 hours of total engine operation.
For the third time, the revitalizant is added in compliance with the same period. No gear oil change is required.

The driver should feel the improvements in the operation of the unit after driving the first 50 kilometers after adding the revitalizant.

Nanoprotec manual transmission

By and large, Nanoprotec MKPP 100 does not differ much from the Nanoprotec MAX additive, however, this revitalizant has some other properties. The purpose is to process parts of a manual transmission of any type, both Russian and foreign. In particular, the manufacturer recommends using the Nanoprotec manual transmission in new cars, in which the box parts have not yet got used to each other.

The advantages that the manufacturer of the liquid guarantees to the consumer:

a more accelerated process of grinding in box elements, in particular - after overhaul unit or in case of purchase new car;
increasing the working life of the checkpoint twice;
the maximum level of protection of the transmission system from increased wear as a result of car operation in harsh operating conditions;
favorably affects both metal and rubber elements of the system, that is, does not destroy them;
reduces the level of vibration and third-party sounds in the operation of the transmission system;
restoration of the geometry of damaged components;
the possibility of short-term operation of the car in the event that there is a transmission oil leak.

In order for the car owner to fully experience the effectiveness of the substance, it is recommended to add the additive to the box twice with an interval of 100 kilometers.

Video "Result of using Xado in checkpoint"

In this video, a car enthusiast describes his impressions of using the Xado revitalizant in Renault Sandero gearbox.

Various noises coming from the gearbox are very common. Their appearance is due to contacts between metal gears, which is quite natural for this unit. Such contacts lead to, noise, wear of parts. Of course, this noise can and should be dealt with, as it can smoothly spill over into more serious problems. Transmissions, and especially automatic ones, are one of the most complex components in a car, which is quite difficult to repair on your own, and the work of professionals is not cheap. Scheduled repairs can be postponed using a non-standard method - gearbox oil additives. There are many additives on the market, however, not all of them can improve the operation of the mechanism, and in some cases even harm. Rating the best additives further in our review.

Additives can relieve gearboxes from noise, vibration, and wear of parts

Mechanical transmissions

It's no secret that manual transmissions, with proper care, can work without breakdowns for a very long time. Quite simply during me the oil in the transmission and skillfully use the "box". The situation changes somewhat if the car is operated in a special difficult conditions under increased loads. In this case, the nodes can wear out with enviable regularity. This problem can be solved with the help of a certain type of additives that are created specifically for manual transmissions.

RVS-Master

The RVS-Master trademark, which is gradually gaining popularity in the domestic market, offers motorists to use TR5 and TR3 additives. It should be noted that this additive can be used not only as an oil additive in manual transmissions, but also for the main gear or transfer case... These products contain silicates in their composition. Their presence causes the appearance of a thin ceramic film on the surface of parts. The film allows you to avoid further destruction and wear of the gearbox elements. In addition, the additive is capable of eliminating defects, but only some of the minor ones. As you know, miracles do not happen.

It is recommended to use these additives regularly. The manufacturer says that with regular use of these additives, the operating time of the transmission will noticeably increase, and it is also possible to exclude the occurrence of any malfunctions even at increased loads. This effect is achieved by restoring the parameters of the parts, and especially the geometric parameters of the gear. This, in turn, gives various positive effects, namely an increase in dynamics, a slight decrease in fuel consumption. There is also a noise reduction effect.

Liqui moly

German manufacturer Liqui moly created an additive called Getrieebeoil-Additiv. Its composition is based on molybdenum disulfide. This metal salt is known to many engineers and avid car enthusiasts. The properties of this salt allow it to form the thinnest elastic film on the surface of parts, which gives the result in the form of a reduction in friction between the components. Due to the lack of direct contact between the gearbox elements, their resource increases.

Additionally, the additive contains a complex based on zinc and copper, which facilitate their deposition on the surface of mechanical gearbox parts. This property is important, as the deposition removes microscopic cracks and small cavities. Long-term use without such damage is extremely rare. As a result, this tool can be used both to increase the service life and to reduce noise and vibration.

Suprotec

In the product line of this manufacturer there is an additive called M100, which is suitable for use in robotic and manual transmissions. The composition contains both organic and. The presence of organic substances allows the formation of a polymer film on the surface of the elements. The disadvantage of this film is its low durability. The film can last only one oil change interval in the gearbox. However, despite such a low durability, the manufacturer says that regular use of the additive will almost double the life of the transmission. Some experts say that this product is capable of constant use and timely replacement oil to increase the resource by a maximum of only 15 percent.

Another claimed property of this additive is to extend the oil drain interval. During its operation, the oil gradually oxidizes and loses its properties. According to the manufacturer, the additive can reduce the rate of oxidation. Indeed, this is so, but oxidation slows down only if some foreign matter gets into the oil. But the agent does not save from oxidation associated with an elevated temperature, therefore, an increase in the interval looks very doubtful. As a result, we can conclude that this additive is suitable only for noise reduction and then for a limited time. In this case, the restoration of the internal parts of the checkpoint does not occur.

XADO

There are several varieties of this additive available on the market. It is produced for robotic transmissions, manual transmissions and automatic transmissions. Its composition is based on "liquid ceramics", which is formed by a complex silicon complex. Together with boron nitrite, the additive very quickly settles on the parts and forms a very strong film, which excludes direct contact of the transmission parts. In addition, the ability to quickly settle allows you to remove many small damages on the surface of components, which also reduces noise.

The manufacturer declared the following capabilities of the 1Stage additive:

increased comfort in the cabin due to reduced vibration levels;
protection of components from destruction at extremely low oil levels;
no strong beating of the gear lever at low loads and at idle.

This additive, like any other, cannot work wonders - if the condition of the gearbox is extremely unsatisfactory, then the additive to the oils cannot rule out any serious breakdowns. Otherwise, the additive will help reduce noise and wear on parts.

Automatic transmissions

Owners of cars with automatic transmission are always happy about their convenience, but this usually happens before serious breakdowns appear. Repairing this difficult unit can turn into a round sum, especially for modern transmissions. For this reason, it is very important to increase the reliability of automatic transmissions. Adding quality additives to the oil will help accomplish this task.

RVS-Master

The range of the Finnish manufacturer RVS-Master contains a special additive created for automatic transmissions. It is also based on a silicon-based substance, namely the magnesium silicate salt. Also in the composition there are substances that allow you to quickly settle on the surface and form a layer of ceramic coating. It is also suitable for continuously variable variators, along with hydromechanical gearboxes. The thickness of the coating can reach a minimum value equal to half a millimeter, which makes it possible to restore gears even in the contact zone. Again, the geometric parameters will be restored and the noise level will be reduced.

The ATR 7 additive, when used in classic automatic transmissions, allows you to get rid of delays during gear changes and slipping. But that's not all, the additive also cleans up various deposits. With so many advantages, the increase in reliability will be obvious. High performance properties and the reasonable price of this additive make it one of the best options available on the domestic market.

Liqui moly

This manufacturer is the first manufacturer to create a special additive for new automatic transmission models. This additive contains no silicon-based components. But there are a lot of detergents in it. Their presence allows you to easily remove various deposits from the valve block, channels and other parts subject to increased loads. Such cleaning will help to increase the resource of the automatic transmission by about 20-30%, postponing the overhaul. As you know, automatic transmissions are sensitive to overheating. Overheating can also occur as a result of a decrease in the throughput in the hydraulic circuit due to the presence of deposits.

An additional effect that this additive has in itself is that it protects plastic and rubber products from increased wear in an aggressive environment. The use of this tool will significantly reduce the possibility of oil leakage through gaskets or other seals. The addition of the agent causes the expansion and swelling of the gaskets, so this agent can help even if the automatic transmission has already begun to leak oil through the seals.

Wynn's

The last resort in our review is an additive from Wynn's. The base consists of organic and metallic components. The principle of action of this additive is similar to those listed above. The product can smooth out micro-damages and restore the surface, dissolve deposits, oils and get rid of noise. This additive is applicable not only for automatic transmissions, but also for all other types of transmissions.

Should you use additives?

Experts strongly recommend that owners of new cars use gearbox additives, and spend the savings on the purchase of high-quality oil. This is especially true for vehicles with automatic transmission. All the necessary additives are already included in the transmission oil. But in the case of used cars, the situation is somewhat different. The amount of additives that are in the transmission oil of a worn-out gearbox may not be enough, so adding them yourself can be beneficial.

In this case, the choice of additive must be approached very carefully. The market is filled with many offers. You should beware of additives that can extend the oil drain interval. Also, you should be alerted by funds that increase the resource of the checkpoint by 3-5 times. There may be deception behind the manufacturer's statement about the presence of nanoparticles. The abuse of such substances can lead to various troubles that could have been avoided.

The gearbox is one of the main units of the car. During operation, if the rules are not followed, the gearboxes wear out faster. This results in noise in the transmission. From this material, you will learn what additives are in the gearbox to reduce noise and whether there is any point in using them.

Is it possible to reduce the hum at the checkpoint?

To reduce noise in the gearbox, you need to figure out what the problem is, because if the bearing devices are worn out, the parts must be replaced, like other worn out elements of the transmission. Carrying out repairs, in terms of reliability, is considered the most the best option... After all, the broken elements will be removed, which will lead to more efficient operation of the unit. Often the appearance of hum and noise in the operation of the gearbox is associated with a lack of oil in the system. With such a problem, it is necessary to add grease to the unit and find out the cause of its leak. If it is associated with damage to the gearbox, then you need to determine the defective place and repair the gearbox.

Machine gearbox

Should you buy additives?

Not so long ago, special additives against hum in engine gearboxes appeared on the domestic market. This option to reduce the noise in the operation of the unit is ideal if the car owner does not want to repair and disassemble the gearbox. Moreover, not everyone can afford to repair the transmission on their own. The use of additives is relevant if the parts and assemblies of the unit have not worn out to a critical state. If the wear of the gearbox parts is large, then the problem is corrected by replacing the components. In this case, it is impractical to add additives.

The use of special means will effectively reduce the noise level in the box, but it must be borne in mind that such substances do not work immediately. It will take a certain amount of time, in some cases, to achieve the result, it is necessary to drive at least 300 kilometers by car. Also, the use of additives makes it possible to soften the operation of the unit as a whole, it will be easier for the driver to switch the gear selector to different modes... In practice, the complete disappearance of noise occurs on average after the car has covered about 500 km.

Choice of additives

Now let's analyze what are good additives in the checkpoint to reduce noise. Additives are used for filling the rear axle, processing synchronizers in manual transmissions and bearings. All additives have a specific composition that determines the technical properties and characteristics of the substance. It is better to pour additives from well-known brands into both mechanical and automatic transmissions. Car owners who choose to use cheap supplements usually don't get desired result in the end. Below we consider supplements from well-known manufacturers that have proven themselves among buyers. It does not matter where they will be poured - into a Niva handout box, a VAZ 2114 or imported cars.
