Very often, when operating a car, noise appears when the gearbox is operating . It occurs due to the contact between metal gears, which is quite common for such mechanisms. To prevent noise and premature wear of parts, various additives are used in the gearbox. Consider the best tools for manual and automatic transmission.
Noise protection - first and foremost
Many drivers are faced with the fact that during operation there are certain problems with the gearbox. And it doesn’t matter which box is installed - automatic or mechanic. Each of them requires timely, and most importantly, close attention. And the most popular problem is the noise that occurs when the transmission is running. In most cases, additives are used as a means of reducing noise. The effect of their application, of course, is, and in general, such tools are pleasing with their functional capabilities. But, besides this, with the help of these compounds a whole series of tasks is solved:
- partially restored the working properties of oil pumps and increases their water density;
- partially damaged surfaces are restored;
- one and a half to two times the service life of the gearbox ;
- the smoothness of gear shifting is improved due to the fact that the loss of efficiency during friction is reduced;
- noise level is reduced to 10 decibels;
- the elasticity of seals and other products with rubber is improved.
The use of gearbox additives to reduce noise is recommended for vehicles of all brands. The main thing is to understand whether the composition is suitable for a specific gear oil.
RVS-MASTER
A mechanical gearbox, with proper care, can work for a fairly long time. But for this you need to change the oil in it in time. But due to high loads, the gearbox still can not cope, and its components begin to wear out faster. Especially for this, various additives are created in a manual gearbox. Reviews of many motorists mention products of the RVS-MASTER trademark.
Additives TR5 and TR3 can be used as an additive to the oil in a manual gearbox. The composition of these products is silicates, due to which a protective ceramic film is formed on the surface of the parts. Its task is to prevent further destruction and wear of gearbox elements and eliminate minor defects on the surface of parts. According to reviews, using these additives you can solve a number of issues with:
- restoration of the geometry of the surfaces of gears;
- noise and vibration reduction;
- an increase in the resource of parts;
- easier and more precise gear shifting.
The manufacturer recommends the use of additives in the gearbox on a regular basis, as this increases the operating time of the transmission and prevents malfunctions, even if the ride is aggressive and with high loads.
LIQUI MOLY
The auto chemical goods of the German manufacturer Liqui Moly is in high demand. It contains molybdenum disulfide, which forms a protective film on the surface of the parts, which minimizes friction between the components. And the lack of direct contact between the elements of the gearbox increases its resource. The Liqui Moly gearbox additive contains zinc and copper, which settle on the surface of a mechanical gearbox and eliminate microscopic cracks and small cavities.
Of course, the manufacturer does not promise that the parts will return to their original shape, but with the help of Liqui Moly tools you can improve the performance of the gearbox, making the shift smoother and lowering the operating temperature. It is necessary to fill the additive with oil when it is refilled or after a mileage of 100,000 km. The additive can only be used with a worn gearbox when signs of prolonged use appear.
This additive in the gearbox receives good reviews, which is explained by the duration of work in the automotive market and the quality of all products. All drivers note that the effect is instantaneous, while there are no side effects.
SUPROTEC
Significant mileage affects the reduction in engine performance. Suprotek company offers to evaluate intelligent lubricants that have passed all tests and certifications. As the manufacturers themselves note, these are not even additives, but modern materials with a complex combination of components. The additive in the gearbox created by the Suprotec brand received good reviews, and users mostly highlight the M100 additive. It can be used in robotic and mechanical gearboxes. The additive combines various substances that form a polymer film on the surface. Its only minus is fragility. It is important that using additives, you can double the service life of the gearbox .
Suprotek is an additive in the gearbox, which forms a new structure of the friction surface. According to the manufacturer, when using these compositions, you can increase the oil change interval. The additive reduces the oxidation rate, but if foreign substances get into the oil, an increase in the interval will not be most noticeable. That is, we can conclude that the additive helps to reduce noise during the operation of the gearbox, but only for a certain time. However, one does not have to hope that the internal parts of the checkpoint will be restored.
XADO (XADO)
The additive in the XADO gearbox was created by a company from Kharkov and has established itself well. The manufacturer focuses on the fact that the compositions contribute to the restoration of the original shape of the parts of the gearbox. And this distinguishes the additives of this brand. XADO gels form a ceramic-metal coating on the surface of parts. Thanks to its special chemical formula, all microcracks are filled with the composition, and the roughness is smoothed out. Even if the car has been used for a long time, and the details of its gearbox have lost their shape, XADO additives will help restore them.
According to reviews, the gels of this Ukrainian brand are ideal for use on worn gears. But, motorists say, ceramic spraying is formed on the engine, which is subsequently difficult to process. Among the additional benefits, users note:
- elimination of potholes, scratches on the working surfaces of the transmission;
- noise reduction;
- optimal operation of synchronizers;
- reduced fuel consumption on all-wheel drive vehicles.
XADO revitalizants should be poured into the same hole into which the transmission oil is poured. The volume of the gulf depends on the volume of the entire oil system.
1Stage
1Stage manual gearbox additives are suitable for worn-out vehicles whose gearboxes require repair. This composition has its own characteristics:
- a cermet film is formed on the surface, which reliably protects it;
- the noise level becomes lower when the gearbox is running;
