    Benefits of CVT Transmission Fluid

    • Transmission lubrication. Unlike a geared transmission, CVT vehicles use a belt drive that helps the engine run efficiently. Modern belt drives are strong and made of steel and composite materials, but in order for them to operate properly they need correct lubrication.
    • More efficiency. The best CVT transmission fluid will ensure that the belt friction is consistent and doesn't shudder. It also protects against wear and corrosion, prevents sludge buildup, and helps sustain viscosity and low-temperature fluidity.
    • Peace of mind. All vehicles require maintenance in order to run properly. Using the proper CVT transmission fluid will ensure that your vehicle drives smoothly, and it's one less thing you have to worry about.

    Types of CVT Transmission Fluid

    Vehicle Specific

    Many automotive manufacturers sell CVT transmission fluid that's specific to certain makes and models. Some brands work for two or three different manufacturers but not others. The reason why is because not all automakers build their own transmissions. For example, JATCO manufactures transmissions for Jeep, Nissan, Infinity, Mitsubishi, and Suzuki. As a result, you may find a transmission fluid that works for a variety of vehicles.

    Universal

    A universal CVT transmission fluid can be used on a variety of vehicles. These are generally good products that may be a little less expensive than vehicle-specific options. Since CVT transmissions are becoming increasingly popular, the number of lubricants available is increasing as well.

    Top Brands

    Valvoline

    Valvoline was founded in 1866 in Binghamton, New York, and is currently based in Lexington, Kentucky. The company has been making lubricants and automotive chemicals such as motor oil, automatic transmission fluid, and antifreeze, for over 150 years. We recommend its Valvoline Continuously Variable Transmission Fluid.

    Castrol

    The British-based Castrol was founded in 1899. Its BP Lubricants is headquartered in Wayne, New Jersey, while Castrol Industrial North America is based in Naperville, Illinois. The company produces a wide variety of automotive and industrial lubricants, such as the Castrol Transmax ATF Black CVT Transmission Fluid.

    Red Line Synthetic Oil

    Red Line was founded in 1979 in Novato, California. The company initially manufactured oils for racing and then started releasing synthetic lubricants for mainstream applications. One of its popular products is the Red Line Non-Slip Continuously Variable Transmission Fluid.

    CVT Transmission Fluid Pricing

    • $15-$20: This is typically what you will pay for a quart of CVT transmission fluid. A manufacturer's "genuine" CVT fluid maybe a little more expensive than a universal brand.
    • $50-$70: Expect to pay this amount for 6 quarts of transmission fluid.  Pay attention to the quantity because some brands sell quarts, while others sell gallons of transmission fluid. European brands favor liters.

    Key Features

    Compatibility

    This is the most important factor to consider when shopping for CVT transmission fluid. It's critical that the lubricant you choose is designed to work with your vehicle's make, model, and year. This confirmation is vital because if you don't pick the right fluid, it can cause a lot of damage, which can be costly.

    Properties

    CVT transmission fluids should perform well in several areas. They should have high steel-on-steel friction and protect against wear, rust, and corrosion. They should minimize sludge and varnish formation and have low-temperature properties so it's easier to shift in cold weather. The fluid should also have foam resistance, good shear stability, and oxidation stability. 

    Other Considerations

    • Cost: As we noted above, the price of CVT transmission fluid is based on the size of the container as well as whether it's a universal product or specific to the type of vehicle you own. It's up to you if you'd rather spend a little more money on an OEM product you know is compatible or save a few dollars on an aftermarket brand. Many universal CVT transmission fluids work just as well as OEM fluids.

    Tips

    • You probably need to replace your transmission fluid if your vehicle suddenly shifts up and down, you hear grinding sounds, your vehicle shifts erratically, or you see a spike in RPMs before shifting.
    • It's critical that your CVT fluid is compatible with your vehicle's make, model, and year. Check the manufacturer's specifications to ensure that it is designed for your particular vehicle.
    • If you put regular automatic transmission fluid into your CVT transmission, it will be extremely damaging and will eventually cause your transmission to die.

    FAQs

    Q: What is the purpose of CVT fluid?

    A: Transmission fluid lubricates the transmission so it can dissipate heat. It also protects against wear and corrosion and helps maintain viscosity and lower-temperature fluidity.

    Q: Is it better to use a vehicle-make specific fluid or one that is universal?

    A: That is a personal preference. Universal CVT fluids tend to be a good alternative to vehicle-make specific brands, and they may also be a little less expensive.

    Q: How often do I need to change my CVT fluid?

    A: That depends on your vehicle. It can be as often as every 30,000 miles to as little as every 100,000 miles. Consult your owner's manual to find out.

    Final Thoughts

    Our pick for the best CVT transmission fluid is the Valvoline Continuously Variable Transmission Fluid. It’s compatible with most makes and models, is less expensive than OEM brands, and does its job well.
