What are the signs of a failing CVT transmission?
A continuously variable transmission (CVT) is an automatic transmission that can provide an infinite number of gear ratios, offering a smooth and efficient driving experience. However, like any complex mechanical system, a CVT can experience issues over time. Here are the key signs that a CVT transmission may be failing and in need of attention.
Slipping or Jerking Sensation
One of the most common signs of a failing CVT is a slipping or jerking sensation when accelerating. This can happen when the transmission is unable to maintain the proper gear ratio, causing the engine to rev up without a corresponding increase in speed. This is often an early indicator of internal wear or damage within the CVT.
Delayed or Sluggish Acceleration
Another sign of CVT trouble is delayed or sluggish acceleration. If the transmission is slow to respond when you press the gas pedal, it could mean the CVT is having difficulty adjusting the gear ratio as needed. This can be caused by issues with the transmission fluid, worn components, or a problem with the CVT's electronic control system.
Unusual Noises
Unusual noises coming from the transmission, such as whining, grinding, or humming, can also signal a problem with the CVT. These noises may indicate worn bearings, gears, or other internal components that require inspection and repair.
Transmission Overheating
If the CVT transmission is running hotter than normal, it could be a sign of an impending failure. Overheating can be caused by low fluid levels, a problem with the cooling system, or excessive wear and tear on the internal components.
Transmission Fluid Leaks
Visible leaks of the transmission fluid, which is essential for proper CVT operation, can also indicate a problem. Leaks may be caused by worn seals, gaskets, or other transmission components and should be addressed promptly to prevent further damage.
Conclusion
If you experience any of these signs of a failing CVT transmission, it's important to have your vehicle inspected by a qualified mechanic as soon as possible. Ignoring these issues can lead to more extensive and costly repairs down the line. By being proactive and addressing CVT problems early, you can help ensure your vehicle continues to provide a smooth and reliable driving experience.

What ruins a CVT transmission?
Overheating: CVTs are sensitive to heat. Excessive heat can degrade the transmission fluid, leading to reduced lubrication and increased friction. This can cause component wear, clutch slippage, and ultimately transmission failure.
What year CVT transmission is bad?
Nissan CVT Problems Overview
Owners of Nissan vehicles, model years between 2013 and 2020, have filed complaints with the National Highway Traffic Safety Administration (NHTSA) claiming that their vehicles have been affected by CVT transmission defects.
Can you fix a CVT transmission without replacing it?
Yes, CVT Transmissions can be repaired, but the most effective way to avoid having to repair them is to make sure that you replace the fluid at Nissan's (or your own manufacturers) recommended Intervals and avoid putting unapproved load or stress on your CVT vehicle (towing or trailering).
How do I tell if my CVT transmission is bad?
CVT Common Problems
- Transmission 'jerking', slipping, grinding or jumping during acceleration when the car is shifting gears.
- Noisy while driving – some customers have issues with a 'whining', 'clanging' or 'rattling' sound while driving especially with Nissan CVT's.
- Contaminated or low transmission fluid.
- Overheating.
Can I drive with a bad CVT transmission?
Continuous driving with a bad transmission causes excessive wear and tear on the engine and drivetrain, potentially leading to failure and expensive repairs. Transmission issues can also cause vehicle computer system malfunctions, affecting overall performance and reliability.
How often should Nissan CVT transmission fluid be changed?
Optimal Fluid Change Intervals
Most manufacturers recommend changing the CVT transmission fluid every 30,000 to 60,000 miles. This interval is designed to ensure that the fluid is in good condition and prevents potential transmission damage.
What does a failing CVT sound like?
In a CVT transmission, whining is one of the most common signs that the transmission is beginning to have internal issues. Rather than using a traditional gear system, a CVT transmission will often use pulleys and a belt to allow constant ratio changes.
How much does it cost to replace a CVT transmission?
$3,000 to $8,000
On average, the cost of a new CVT transmission can range from $3,000 to $8,000, including parts and labor. If your vehicle experiences transmission issues while under warranty, the cost of a new transmission should be included.
What happens when a CVT transmission goes out?
When this happens the car loses power and seems to rev higher like it can't into lower gears. It feels like it is slipping or not fully engaging. You would notice that you can't get past a certain speed below the highway speed limit. After the transmission cools in a few hours it's back to normal.
