CVT fluid certainly wears out over time. It should be changed much sooner than automatic or manual transmission oil. CVT fluid has to be in acceptable condition to protect against metal-to-metal contact. It also has to provide the correct frictional properties.
Does CVT transmission fluid need to be changed?
The short answer is Yes. Just like other automatic transmissions, you need to check, maintain and occasionally flush the transmission fluid on a CVT. Check your owner's manual for more details.
When should CVT fluid be changed?
Continuously variable transmissions, or CVTs, are another animal altogether. They are unlike any other type of transmission. Change the fluid according to the manufacturers recommended interval, which should fall somewhere around the 100,000km range.
What happens if I don't change my CVT fluid?
If you don't change your transmission fluid frequently, the dirty fluid will not serve as an effective lubricant and it won't disperse heat well. This will cause wear and tear on the clutches and other parts of your transmission.

How do I know if my CVT fluid is bad?
Muddy Fluid - Muddy fluid or debris filled fluid could be a symptom of bad CVT transmission. If it has a slightly sweet smell and is bright red in colour, then that is working correctly. If the fluid in the transmission starts to look murky, do what you can to get it changed immediately.
How much does it cost to change CVT fluid?
The transmission fluid used on a CVT is expensive and ranges from $15 to $30 a quart. The transmission's capacity is 4 to 5 quarts. The labor to change the fluid can be from $70 to $110. If you add it all up, for between $120 to $260 you can prevent a major problem!
How long does a CVT belt last?
The typical CVT lasts over 100,000 miles. Like any other transmission though, making sure that it's taken care of will help ensure that you get as much life out of your transmission as you can.
Is it bad to change the transmission fluid?
If you drive manual, most manufacturers will recommend changing your transmission fluid every 30,000 to 60,000 miles. If you have automatic, you can typically boost that range up to 60,000 to 100,000 miles. There's no harm in changing your fluid early.
What color is Nissan CVT fluid?
Nissan CVT fluid is golden in color like motor oil. At no time was it ever red. Nissan is very explicit about using only their fluid as it's specifically engineered for their CVT's. The fluid is actually an integral part of the CVT's operation and was a major breakthrough in terms of CVT technology.
Why do Nissan CVT fail?
Nissan has been accused of using an inadequate cooling system for their transmission. As the CVT heats up it can vibrate excessively. And when it overheats it sends the car into fail-safe mode which limits engine RPMs as it tries to prevent damage.
Are all CVT transmissions bad?
CVTs can be expensive to repair or replace when compared to a conventional automatic transmission. Some of the common problems that owners run into include overheating, slipping, and sudden loss of acceleration. They don't last as long as a conventional transmission.
