How Often to Change CVT Transmission Fluid?

You must hear of continuously variable transmission fluid. Many people asked questions about how often to change CVT transmission fluid? Gearbox maintenance is very significant. This gears are like a secret weapon for keeping your car running at its best. The only thing stopping them from performing their full potential is the transmission oil.

This liquid in your car has to deal with the constant changes it undergoes. For example, when you are moving, your engine heats the lubricant to work more efficiently as it moves throughout the gears. After you have stopped, the heat from the engine has a chance to escape and consequently cools down the oil. Many wears and tear can happen quickly during those cycles, so it is vital to change your gear fluid regularly to keep everything functioning correctly. Follow the below guide to get your answer:

How often to change CVT transmission fluid?

Your car will decide how long you may drive between CVT fluid changes. This may depend significantly on how much you drive. If you drive a lot, you should change it every 30,000 miles.

Nissan suggests changing the oil per 25,000 miles. The majority of manufacturers have a range of 30,000 to 50,000 miles for their vehicles. Knowing your car and its suggested service intervals is excellent advice, as it will help you get the most out of your vehicle’s lifespan.

It’s worth remembering that transmission fluid change periods vary greatly. It ranges between 30,000 and 100,000 miles for some cars and trucks. Gears in certain new vehicles, notably those with automatic gearboxes, include liquid that is supposed to last the vehicle’s whole life.

Different Cars CVT Fluid Change Interval data-

Different Cars gear oil change intervals based on Varies. Below we will discuss some well-known models most recommended change interval data.

Nissan recommends changing the CVT transmissions liquid in every 25,000 miles. According to Toyota, automatic cars demand a transmission oil replacement every 50,000 to 100,000 kilometers. Oil changes are required every 35,000 to 70,000 kilometers for manual transmissions.

Hyundai Kona gearbox filter replacement is recommended every 30,000 or 50,000 miles. On the other hand, The BMW transmission filter will require replacement every 30,000 or 50,000 miles. In general, it depends upon the manufacturer’s vehicle lineup.

If you intend to keep your CVT-equipped vehicles, you should replace the gearbox lubricant almost any 60,000 miles. Alternatively, you can replace the oil if the degeneration data appears to exceed 210000. If transporting a vehicle or driving on rough or swampy roadways, the CVT fluid needs to replace almost 30,000 miles.

How to change CVT fluid?

CVT fluid is a particular kind of transmission oil. Drivers and Mechanic should know CVT fluid change process time as it is not a normal procedure. CVT change The vehicle’s manufacturer specifications followed to perform the changing procedure. Here is a step-by-step guideline-

Step 1:

Start by driving the car for 10 minutes to warm it up. You can park the car, go through all the gears and then turn off the engine. When you take the dipstick out of the engine, wipe it down, and then put it back in the machine again. Rotate 180° and push down. Take it out again and verify the level.

Note: The second notch is where you will refill the liquid. Here is where you’ll add the gear lubes.

Step 2:

Move the front end of your vehicle some way. You can drive up to them if you have small ramps for an oil change. Turn off the car.

Step 3:

Now, take out the dipstick. Place a collection tray underneath the drain plug for the gearbox. The hex screwdriver/tool is used to unscrew the drain plug. It is easy to do, and it won’t take too much force. Allow the liquid to drain. I left mine to drain for around 15 minutes.

Step 4:

Replace and adjust the drain plug. To fix the drain plug, you can change its O-ring.

Step 5:

Use your container marked at 1 Qt to measure how much fluid you have drained. You can add the exact amount you used to drain the CVT oil back into the transmission via the recharging line (where you took the dipstick out).

Step 6:

Lower the vehicle. Confirm the liquid level and run it through all the gears once more. As required, adjust the fluid.

CVT transmission services-

Some of the services offered by a CVT service include oil exchange, flush, automatic transmission repair, and filter change. CVT fluid exchange interval depends upon many factors.

The fluid exchange service involves the replacement of the CVT transmissions oil with the recommended type of CVT liquid. The transmission is generally serviced after the lube exchange service. Check the CVT oil color before changing.

The vehicle’s recommended CVT fluid, which is silicone-based, also helps to improve gas mileage and comfort by enhancing the shifting ability to cope with rapid changes in torque and changes in engine speed.

The recommended one is called “Silent CVT Transmission Lubricant,” It has the same viscosity as the original product. The liquid exchange service is usually required when an automatic transmission replaces a manual one. The automatic transmission fluid in the new gears  should change with the recommended one.

A CVT’s liquid cost is between $15 and $30 per quart. The transmission can hold 4 to 5 quarts—labor fees to change the liquid range from $70 to $110. You can avoid significant problems by adding it up for around $120 to $260.

3. Should I change CVT fluid after 100,000 miles?

Yes, after 100,000 miles, it is necessary to change the gear lube. Service intervals can exceed 100,000 miles for new vehicles before you need to do this.

4. Why Never Flush Transmission Fluid?

Transmission liquid, which is high in detergent, can strip the varnish from the clutches and cause them to slip. Pressure flushing could cause ageing seals. If it leaks for more than one quart, it can cause it to burn.


continuously variable transmissions fluid is an essential part of your car’s engine. It keeps the gearboxes in good working condition and helps keep it from getting stuck in one gear or another. It also prevents damage to the transmission by absorbing vibrations, heat, and other harmful factors. When changing the oil, you should pay attention to the recommended intervals. Hope now you understand how often to change CVT transmission fluid.
