How to Choose The Best Racing Transmission Fluid

When it comes to choosing the best racing transmission fluid, there are several options available from multiple brands and manufacturers. While this is a tough decision to make, there are quite a few factors that make the decision easier for you. Let us take a look at the factors you must take into account to choose the right transmission fluid for racing vehicles.

Type Of Fluid

To choose the right transmission fluid for your racing vehicle, the first factor that you have to take into account is the type of fluid. In the automobile industry, there are usually two types of transmission fluids available: synthetic and conventional.

Each of these types has a specific formulation and additive packages present and provides a slightly different performance. The type of fluid you choose will depend on the transmission you have and the requirements of your vehicle.

Between these two types, conventional fluids are the oldest and work with a wide variety of cars and bikes, including the older models. On the other hand, synthetic fluids are a recent formulation and ensure a better and long-lasting performance.

Transmission Requirements

In the automobile industry, there is a wide range of different transmissions available, depending on the make and model of the vehicle. While the main purpose of each and every transmission is the same, the requirements slightly vary on quite a few factors.

While purchasing a transmission fluid, you will have to consider the requirements of the transmission and make sure that the liquid matches all the standards to ensure proper and accurate service.


Even though it is not an independent decision factor for transmission fluid, taking the manufacturing brand into account tells a lot about the product and its qualities. While there are more than a hundred brands available in the market, not all of them sell quality transmission fluids.

Each brand has a slightly different formulation and this formulation plays a major role in the service provided by the fluid. Make sure that you take the formulation and the reputation of the brand into consideration properly.

Additives And Agents

Each and every transmission fluid have a different set of additives and agents included in the formulation to enhance the overall performance and protect the transmission. The most common agents used in a liquid are cleaning, cooling, anti-friction, anti-rusting, and many more.

All of these additives play a specific and significant role when it comes to improving the durability or performance of the transmission oil. Before making a final decision, make sure that you are aware of the friction modifiers additives required by the transmission of your vehicle and whether the transmission fluid includes all of the necessary agents or not.


Last but not least, I’ll have to take the pricing of the transmission fluid into account. Vehicle maintenance is undoubtedly expensive and you need a decent amount to ensure that your transmissions are running smoothly.

In cases like these, it is essential to stick to a budget so that it does not put a dent in our wallets. The cost of transmission fluid varies depending on several factors, including price, availability, durability, and so on.

There are options available in the market that start from as low as $20 per quart and go as high as $50 or more. Conduct proper research before purchasing a transmission oil and make sure that it fits your budget.

As discussed earlier, there are typically two types of transmission fluid available in the market: synthetic and conventional. While both of these types ensure proper performance, there are slight differences between the two due to formulation.

When it comes to racing cars, both of these types of transmission fluids are suitable depending on the transmission requirements. However, experts and enthusiasts typically prefer the use of synthetic transmission fluids as it provides improved performance and durability compared to conventional fluids.

How And When to Change Racing Cars Transmission Fluid

There is no proper or accurate time for replacing the transmission fluid in a racing car. Experts or racing car drivers usually change the transmission fluid by conducting a fluid check before the race.

Not only that, but a regular checking schedule will also indicate whether the fluid of your racing car requires replacing or not.

When it comes to changing the transmission fluid in a racing car, you typically have two options available. You can either change the transmission fluid on your own for your car, or you can get the replacement done by experts.

I typically recommend the help of experts to replace the fluid in case you do not have complete knowledge about the vehicle, otherwise, this can significantly damage the transmission.
