Additive in automatic transmission against kicks: features and rating of the best manufacturers

Additives are added every 10-20 thousand kilometers. But you can not use them more than three times on one ATF fluid. Cleaning compositions must be filled with each filter change.

To improve the performance of automatic transmissions, motorists buy special additives - substances that reduce the level of wear and noise during operation. There are several types of such liquids in stores, each with its own purpose.

What are additives in automatic transmission

This is a liquid that is poured into the box to extend the life of internal parts, reduce noise, and eliminate shocks when shifting gears. Some additives clean the working mechanisms of the box.

These are useful properties, but autochemistry is not a panacea, and therefore there are restrictions on use.

It is useless to pour liquid into an old box that has been malfunctioning for a long time - only a major overhaul will help.

Also, manufacturers often embellish the capabilities of additives for the sake of a marketing ploy. Therefore, in the store you need to look not for a specific brand, but to study the reviews of real owners in advance in order to understand whether chemistry is suitable for solving specific problems.

Composition

Manufacturers do not publish exact data on the components of products, but their analysis shows that additives contain additives from high molecular weight polymers. Thanks to them, a protective film is created on the surfaces of the parts, which prevents dry friction.

And in order to restore a small layer of worn parts of automatic transmissions, revitalizants are used - tiny particles of metals. They settle on parts, penetrate cracks and reduce gaps. Additionally, a ceramic-metal layer is created that can withstand loads.

The best additives form a reliable coating up to half a millimeter.

The purpose of additives in automatic transmission

Autochemistry was created to solve several problems. The main goal is to reduce wear on the rubbing parts of the box.

Wear of automatic transmission parts

Manufacturers point to the lack of effectiveness of standard gear oils. Over time, they lose their original properties, oxidize and become contaminated. And the oil filter of an automatic transmission does not always work properly. Therefore, additional additives are needed to preserve the properties of gear oils.

Noise and vibration reduction automatic transmission

If the box is badly worn, a characteristic noise will appear during operation. Additives help get rid of scoring and create a layer to protect against friction.

Some formulations contain molybdenum. It is an effective friction modifier that reduces loads and temperatures at the points of contact. Thanks to this component, the box is less noisy, the vibration level is noticeably reduced.

Oil pressure recovery

The integrity of the system plays an important role here. If there are gaps between the metal and the gasket, the pressure will decrease. Molybdenum also plays an important role in the additive for system recovery. It returns the elasticity of plastic and rubber, and therefore the gear oil stops leaking out of the box. The pressure is back to normal.

Oil leaks from the gearbox

Some compounds increase the viscosity of the ATF, as a result, gear shifting becomes smooth.

Types of additives in automatic transmission

Manufacturers produce narrow-profile types of chemistry. Therefore, they are conditionally divided into the following types:

• increasing the durability of parts;
• reducing noise;
• restoring wear;
• preventing oil leakage;
• eliminating jerks.

Experts do not recommend buying universal formulations. As a result, they will not be able to cover all problems at once.

How to use additives in automatic transmission

The main rule is to read the instructions before starting work, because each composition has its own characteristics.

General recommendations:

• fill only after the machine has warmed up;
• the engine must run at idle;
• after pouring, you can’t accelerate sharply - everything is done smoothly with a gradual switching of all stages of the box;
• cleaning additives are required when buying a car from hand;
• to feel the difference in work, you need to drive about 1000 km.

Additive application

Do not exceed the allowed amount of liquid. From this, the work of the additive will not accelerate.

What is the best automatic transmission additive

There is no perfect additive that solves all problems. The choice depends on the faults of the particular machine. And it is important to understand that serious damage cannot be fixed with auto chemicals. Manufacturers are trying to convince motorists that their automatic transmission additive is the best, but this is just a publicity stunt.

Rating of additives in automatic transmission

If there is no opportunity or desire to study the characteristics of different types of chemistry, you can narrow your search to a list of trusted brands.

Liquid Moly ATF Additive

The additive in the automatic box is compatible with ATF Dexron II / III fluids.

Liquid Moly ATF Additive

Suitable for improving the elasticity of rubber seals and cleaning the channels of the transmission system.

Tribotechnical composition "Suprotek"

Russian-made composition for the restoration of worn gearbox mechanisms. Differs in an optimum ratio of the price and quality. The effect is achieved due to the balanced composition of the crushed minerals of the group of layered silicates. When mixed with oil, it does not change its properties.

XADO Revitalizing EX120

The additive in the automatic transmission reduces the level of vibration and noise. Also used for restoring parts.

XADO Revitalizing EX120

The store has different subtypes of composition. Used on diesel and petrol engines.

Hi Gear

American-made additive to keep the new automatic transmission in working order. With regular use, the service life will increase by 2 times due to a decrease in gearbox overheating. The composition is suitable for motorists who are accustomed to abruptly move off and slow down.

Frontier

The Japanese composition is produced in two packages. The first is to clean the box, the second is to increase the resistance of parts to friction. With preventive use, you can get rid of shocks in the CP.

Wynn's

Serves to reduce wear of mechanisms and improve gear shifting. Also, the Belgian additive makes rubber gaskets elastic.

According to reviews, this is one of the best fluids for the box, which effectively eliminates extraneous noise.

How often to use

Additives are added every 10-20 thousand kilometers. But you can not use them more than three times on one ATF fluid. Cleaning compositions must be filled with each filter change.

How to choose an additive in automatic transmission

Before buying, you need to decide on the problem of the car. Based on this information, it will be possible to find the correct additive by studying its purpose. Motorists also pay attention to the ratio of price and volume in the package, interaction with already filled oil and feedback from people who have used additives.

Safety Precautions

It is allowed to work with chemicals only in protective gloves and goggles - to avoid burns to the skin and mucous membranes.

In order not to worsen the condition of the box, additives should be bought only from an official representative - it is strictly forbidden to pour various homemade products or liquids without packaging into the car.

Reviews car owners

Drivers are satisfied with additives, but they believe that they are most effective with proper car care - timely replacement of consumables and filters. After filling, motorists note a smoother gear shift and an increase in the life of the automatic transmission.

But, according to reviews, there is also a minus - some additives are incompatible with the oil that the owner is used to pouring into the car. This information can be found by reading the label on the package.
