The efficiency of the car's gearbox is in second place after the engine. Without a properly functioning transmission unit, the continued operation of the vehicle becomes extremely dangerous. Therefore, the task of each car owner is to maintain the optimal state of the gearbox, regardless of its type. The problem of transmission wear can be solved in several ways, one of the most common among which is the use of special additives. However, not all drivers know which additive is better to pour into the gearbox and which additive to give preference. To answer this question, we have prepared for you a rating of the best tools for in-place repair. But remember that additives can not be perceived as a panacea for all diseases. With a critical degree of wear, even the most expensive and effective additives will be useless. Therefore, learn how to correctly apply and use them only as needed.

Ways to reduce noise in CAT

Extraneous sounds always irritate the driver and cause anxiety. If something is noisy, then somewhere there is an obvious problem that must be solved. Do not forget that with a properly working gearbox, no extra sounds should arise. If you notice that there is noise when driving or shifting gears, you need not pull and ask for help. Diagnostics will make it clear what is wrong with the checkpoint and what measures are appropriate to eliminate the problem. Practice shows that box noise is caused by several main reasons:

• increases the gap between the details of the transmission;
• Gearbox teeth wear out;
• Transmission oil viscosity is impaired.

And here arises the logical question of how to get rid of noise. To solve this problem, there are several solutions.

1. Ignore extraneous noise. Despite the absurdity of such a decision, it is chosen by many car owners. It doesn't end well. Sounds gradually amplified, the box ceases to function normally. It all ends up with an expensive repair, and sometimes a complete replacement of the gearbox.
2. Disassemble the box, find the problem and fix it. A good way to take time and money from you. Dismantling some gearboxes takes a lot of effort and requires significant investment. The repair is not always worth it, since an elementary problem is found that can be fixed without dismantling.
3. Use additives. They are intended for partial repair of minor faults. Experts advise to use them not after the appearance of extraneous noise, but for prophylaxis in order to prevent the appearance of these same sounds. Protecting from premature wear, the additives are effective for a long period of time. But when wear makes up more than 50 - 60% of the PPC resource, no additives will help. You need to disassemble the box, change worn components, drain the old oil and reassemble the assembly.

As you can see, the additives do not save from serious problems. But with their help, you can fix some problems, extend the service life of the gearbox and avoid costly repair of the transmission. Not all additives are equally effective and beneficial. Plus there are two separate categories of supplements that are designed for:

• manual transmissions;
• automatic transmissions.

And pour additives for automatic transmission in the mechanics is not recommended, and vice versa. Carefully approach the issue of choice, and try to use only the most high-quality and effective mixture. Only they will be able to justify the financial costs and ensure the result. A number of additives turn out to be empty and do not affect the operation of the gearbox. Sometimes it happens that the use of additives leads to even more serious consequences and failure of the transmission.

When to use

Depending on the composition and properties of the transmission additives, they can perform various tasks:

• protect against oil oxidation processes;
• slow down the aging of the lubricant;
• provide a tighter enveloping of box parts;
• to resist rust and corrosion;
• increase the service life of the automatic transmission and manual transmission components;
• thicken the oil when its temperature rises;
• provide washing and dispersing effect, resisting the formation of deposits;
• increase the stability of the lubricant to low temperatures;
• prevent the formation of foam in the oil.

Some additives should be used on an ongoing basis in order to maintain the performance of transmission parts. Others are suitable for emergency use to quickly cope with the problem. It is not always worth waiting for an instant effect from the additive There are many additives that react and manifest themselves after a certain number of kilometers traveled. Their action is tied to the physico-chemical processes.

These tools are designed specifically to improve the quality of the box, depending on what problem it pursues. Therefore, their action is reduced to:

• increase the operational life of the checkpoint;
• noise reduction;
• the elimination of vibrations;
• restoration of damaged transmission surfaces;
• ensure smooth gear shifting.

If you want to choose and use supplements yourself, you should be extremely careful. Many of them are incompatible with each other, because their combination can lead to sad consequences. Also, each supplement has its own nuances of application. It is impossible to apply different additives according to the same scheme. Be based on official manufacturer instructions. Now we suggest studying the rating of the best transmission additives used in automatic transmissions and manual transmissions. Segment leaders were determined based on the opinions of car owners, expert opinion and tests carried out in the framework of various tests. This allows you to determine the leaders as objectively as possible and to be confident in the effectiveness and efficiency of these additives.

Manual gearbox

Mechanical boxes, due to their simpler design, are considered sufficiently resistant to wear. Problems with them arise much less when compared with automatic transmissions. But if the manual transmission is regularly used in difficult conditions, the service life will be significantly reduced. To protect the box from premature wear, eliminate noise, and restore normal friction between surfaces, high-quality additives are required. And to choose better proven firms, in the effectiveness and efficiency of which there is no doubt. Therefore it is not surprising that these manufacturers were included in the rating. They produce the best additives for manual transmission.

Take or not take

A number of drivers do not even doubt the usefulness and effectiveness of automotive additives for the engine and gearboxes. But there are ardent opponents of auto-chemistry, who consider additives as simple marketing tricks, from which there is no real sense. But numerous tests and tests have proven that additives can bring significant benefits to vehicles. But only if they are properly applied. You can not mindlessly pour into the gearbox the first available additives just because the manufacturer promises you an amazing effect or instant recovery of the transmission. This can not be.

Before buying transmission additives, be sure to review the composition, application features and compliance of the additive with the oil used, which is filled in the manual transmission or automatic transmission. If you use auto chemical goods correctly and in a timely manner, it will improve the quality of transmission work, really increase its resource and help prevent a number of problems. Additives have many pitfalls and pitfalls. If you do not know about them and do not take into account in the process of use, you will do more harm than good to your vehicle.

Do not forget about the existence of universal and special additives. Some are directed, rather, to the prevention and simple maintenance of the box. Special additives are designed to solve specific problems. If you are not aware of the current state of the transmission, do not know its problems and weaknesses, the use of incorrect chemistry will only aggravate the situation.

It is impossible to consider different liquids and sprays for manual transmission and automatic transmission solution of all problems. These are often temporary measures and tools to deal with minor faults. More serious damage is solved only by a full repair of the gearbox. And for this you need to diagnose, disassemble the checkpoint, identify the problem and fix it. Already then, in order to prevent and prevent the recurrence of a similar problem, a suitable additive can be added to the assembled box.
