What Should I Know Before Buying Transmission Additives?
The transmission system in your vehicle experiences friction daily due to the moving parts in the gearbox. The motion of these parts means that they need to be lubricated well for them to function at optimal levels. If this is not done, the components will gradually wear out, breaking down into smaller debris that will get mixed with the transmission fluid.
The transmission fluid will then get discolored and broken down. The fluid will lose its lubricating ability with time, leading to more friction and heat generation in the transmission system. This will cause the fluid to break down even more and wear out transmission components. The leading cause of these problems is the accumulated debris in the transmission fluid.
Transmission additives fix this issue in many ways depending on the type of transmission you use and the type of additive you are getting. Some additives coat the surface of the transmission system, which reduces friction-related wear and increases the lubrication of the system. Other additives perform this task by breaking down the debris or cleansing the fluid and transmission.
Here are the various factors you will need to consider before purchasing transmission additives for your vehicle:
Read more: What Does Transmission Fluid Smell Like?
The type of transmission additive you get has to be compatible with your type of transmission system. We are talking about manual or automatic transmission. Automatic transmission fluids and additives can be used in manual transmission systems, but you will first need to check, or the original equipment manufacturer recommends it. This information is usually on the owner’s manual.
Automatic transmissions are more advanced and complex when compared to manual transmissions. Manual transmissions require the driver to operate the clutch and choose when to shift gears. On the other hand, automatic transmissions automatically choose what gears to select concerning the engine speeds and conditions on the road.
With that said, you can tell manual transmissions will have more friction and generate more heat due to the manual operation of the gears. Therefore, manual transmission fluids and additives are made to counter these effects by having high viscosity, heat resistance, and the ability to withstand huge pressures. Automatic transmission fluids and additives prioritize anti-foaming characteristics and low viscosity.
Additive composition regards the ingredients used to make the transmission additive. You want to get an additive with a great set of ingredients since it will be more effective and increase the transmission performance by a huge margin.
Company reputation is a huge deal when it comes to buying transmission additives. Popular brands are more reliable and provide better quality products that will be worth your money. Premium products from reputable brands like Prolong will give you the best transmission treatment.
Another factor to consider for the best quality is the price. Cheap transmission additives will not provide you the best protection and may end up causing more problems down the line as they fail to perform their tasks effectively.
Get a bigger-sized transmission additive if you plan to treat your transmission more than once. It would be great to know the amount you need for a single treatment lest you find the one you purchased isn’t enough. The size will also affect how much you spend on the additives per year. A high-capacity additive bottle is a way to go if you want to spend less.
On top of the additive composition, you also need to consider the additive formulation that gives each different blend special features. Some of the remarkable benefits of additives include oxidation prevention and noise reduction.
The most suitable transmission additive for your vehicle is one that your vehicle manufacturer recommends. It would be best to avoid using additives that are not suitable for your vehicle since they will cause more issues and void your warranty in some situations.
Vehicle manufacturers, as well as transmission additive producers, indicate which additives are suitable for specific vehicles. Make sure to pick only the ones recommended for your car.
Transmission additives and fluids are not added regularly like engine oils. You will not need to use the transmission additives unless your transmission starts to face a few issues like seal leaks, slippage, and rough shifting. The first step is to take the vehicle to the repair shop to ensure the problem isn’t bigger than simple additive/fluid issues.
We recommend you get the Prolong Super Lubricant Transmission treatment if you have a new vehicle. The unique metal surface coating compound will extend the lifespan of your new car by reducing leaks, slippage, and friction-related issues.
