5 Best CVT Transmission Fluid Reviews and Complete Guide 2021

CVT stands for Continuously Variable Transmission. It is also known as shiftless transmission. It works like an automatic shifter used for seamless shifting in a range of gear ratios. To keep the CVT at its best performance and more durable, you need to use a CVT fluid for lubrication. You might be thinking that you can use any lubricant on your CVT but that is wrong. CVT fluids are more model-specific and are different from lubricants used in other automatic transmissions. With the many choices in the market today, we shall guide you on the best CVT transmission fluid to use.

CVT vs. Automatic Pros and Cons

Transmissions are of three types. There are automatic, manual, and CVT transmissions. CVT is the most recent transmission type found in modern vehicles. Each of them has its cons and pros. CVT and automatic transmissions are somehow similar since they do not need any driver input to change the gears but they also have their differences. So what is the difference between CVT vs. Automatic transmissions?

Best CVT Transmission Fluid

Continuously Variable Transmissions (CVT)

CVT unlike automatic transmissions uses two cone-shaped pulleys. One of these pulleys is connected to the engine while the other one joins through the transmission. The width of the pulleys varies depending on the power inputs and that’s why it is called Continuously Variable transmissions. The pulleys work in tandem allowing CVT to accelerate in strength and smoothness.

As the speed of the engine changes, the CVT enables you to change the gear ratio. This means that the engine performance is always at the optimum. The number of gear ratios in CVT is infinite. The flexibility and seamlessness help CVT to pull optimum horsepower from small engines which gives the drivers quicker and smoother acceleration compared to automatic transmissions.

CVT produces fewer emissions and works more effectively due to its ability to control engine speed range. They are lighter in weight compared to automatic transmissions and they have better fuel efficiency.

Pros

  • Increased fuel efficiency
  • CVTs are smaller sized and lightweight
  • Less complicated and easier to assemble
  • Offers Velvety performance

Cons

  • Not designed for power
  • Needs high routine maintenance

Automatic Transmissions

These transmissions are comprised of a complex series of clutches, brakes, gears, and principal devices. Normal automatics have a finite number of gears known as speed. For instance, a 6-speed automatic means that the transmission is equipped with 6 gears. The gears are set to reach the car’s speed only when the driver goes on accelerating.

As the driver accelerates, the transmission shifts up through the gears starting from the first one. Modern automatic transmissions contain up to 11 gears. The ratio helps the vehicle delivering responsive performance or maximizing fuel efficiency depending on the application.

Unlike CVT vehicles that need special parts, transmission fluid, and oil, automatic transmissions are much easy to maintain. The automatic transmission does not need as regular maintenance and repairs as the CVT. When the repairs and maintenance are done they are not as expensive as those of CVT vehicles.

Pros

  • More engaging driver experience
  • Less costly to maintain
  • The more connected sensation between the speed and engine
  • The driver is in more control with downshifting and upshifting

Cons

  • Less fuel-efficient compared to CVT
  • Produce more emissions

CVT transmission Fluid Buying Tips

It is easy to get confused about the CVT fluid to buy with the many brands in the market. Transmission fluids are made for specific CVTs and vehicle models. It is therefore important to learn the things to check to buy the right CVT fluid for your vehicle. Here are some of the buying tips:

Type of CVT Fluid

The first thing to check when buying a CVT lubricant is its type. Transmission fluids are available either vehicle-specific or universal. Vehicle-specific transmissions are specifically made for specific vehicles. In this case, you need to be very sure that the fluid you are buying has been made for your vehicle model.

Universal CVT fluids can be used on a wide range of vehicles. These fluids tend to be less expensive compared to vehicle specific. As the CVT transmissions are increasing, the numbers of lubricants are increasing as well. It is crucial to contact the car manual and see the recommended CVT fluid to avoid voiding the vehicle’s warranty.

Properties

It is crucial to check what the CVT fluid you are purchasing is made of. The best CVT transmission fluid should protect the system from corrosion, rust, and wear and tear. It should also feature high steel-to-steel protection. The fluid should also have cold temperature properties which will enable it to function easily in cold weather. Other properties to look for are oxidation stability, good shear stability, and foam resistance.

Compatibility

The best CVT transmission fluid is the one that is compatible with your vehicle. Make sure that you get a transmission fluid that is compatible with your vehicle’s model, make, and year. Using the wrong CVT on your vehicle may result to also of damage which ends up being quite costly.

Price

The price of the CVT fluid mainly depends on the container’s size or whether the fluid is universal or vehicle-specific. It is more advisable to spend some more money buying an OEM fluid which you are sure is compatible with the vehicle and it may save you in the long run. Do not compromise the quality of the fluid because of the price.

Frequently Asked Questions (FAQs)

Best CVT Transmission Fluid

Q: Can You Put Regular Transmission Fluid in a CVT Transmission?

 You should never use regular transmission fluids in a CVT since it will lead to damage to the transmission. In case you have put the wrong fluid in the CTV, the most advisable thing to do is to have it drained. In case there was a little CVT fluid and you happened to add an ATF fluid then it will work for a little while but later cause permanent damage.

Therefore, if you realize that you have used the wrong fluid in the CVT, remove it as soon as possible and it will save you from replacing the much expensive transmission. Some of the warning signs that you have used the wrong fluid for CVT are clutch locking up, gears slipping, rough shifting, gears refuse to shift, stalling after changing gears, and strange engine sounds.

Q: What Is the Purpose of CVT Fluid?

CVT fluid works as a lubricant for CVT transmission. It is made with friction modifiers which enables the belts in the transmission to grip on the pulleys. It offers engineered anti-shudder performance leading to a smooth transfer of power. The fluid also provides anti-wear and anti-oxidation protection for sophisticated CVT transmission.

Q: Does CVT Transmission Fluid Need to be changed?

Yes, the CVT fluids need to be inspected and change once in a while. It is advisable to read the vehicle manual to see after how long your vehicle manufacturer advises you to change the CVT fluid. Changing the CVT fluids as recommended offers you optimal vehicle performance and also increases the life of the transmission. CVT fluids produce more fiction since it runs a pulley system that runs by belts. The fiction is therefore needed to prevent the belts from slipping from the pulley.

Q: Is CVT Fluid the Same as Transmission Fluid?

No, CVT fluid is not the same as transmission fluid. Transmission fluids are designed to be used on automatic transmissions while CVT is specifically formulated to be used in CVT transmissions. Transmission fluids should never be used on CVT transmissions and vice versa is true.

Q: How Often Should CVT Transmission Fluid Be Changed?

How often you should change CVT fluid depends on the type you are using and how often you use your vehicle. Most of the CVT fluids made by renowned automakers last up to 5 years which is around 100,000 miles. However, the CVT transmission fluid change period will also vary with the build quality and owner’s maintenance.

Final Words:

The best CVT transmission fluid helps in dissipating heat in the transmission. On top of this, the fluid protects the surfaces from wear and corrosion and also provides consistent belt friction. A good CVT fluid should be able to maintain low-temperature fluidity and viscosity. Make sure you choose a transmission fluid that is compatible with your vehicle model. The above-discussed CVT fluids are some of the best from reputable companies and they will not disappoint you.
