  • Strange noises or vibrations from the transmission
  • Slipping or jerking during acceleration
  • Loss of power or difficulty in maintaining speed
  • Irregular shifting or failure to shift

If you experience any of these symptoms, it is essential to consult a professional mechanic or perform a diagnostic scan to identify the specific issue. They will use specialized tools and computer software to retrieve error codes and diagnose the problem accurately.

Once the problem is recognized, it’s time to delve into the repair process. Here are some common CVT transmission problems and their potential solutions:

1. Overheating Issues

One common problem with Nissan CVT transmissions is overheating, which can cause extensive damage if not addressed promptly. Overheating usually occurs due to low or leaking transmission fluid, restricted fluid flow, or a malfunctioning cooling system. To repair this issue, follow these steps:

  • Check the transmission fluid level and condition. If it is low or contaminated, replace it with the recommended fluid type.
  • Inspect the transmission cooler and cooling lines for any leaks or blockages. Repair or replace any damaged components.
  • Clean the transmission cooler and cooling lines to ensure proper fluid flow.
  • Verify that the radiator fan is functioning correctly to prevent excessive heat buildup.

By addressing the overheating issue and maintaining proper fluid levels and cooling system functionality, you can extend the lifespan of your Nissan CVT transmission.

2. Fluid Contamination

Contaminated transmission fluid can lead to various issues, including slipping, jerking, and decreased performance. Here’s how to address fluid contamination:

  • Perform a thorough flush and fluid replacement using the recommended CVT fluid.
  • Inspect the transmission pan and filter for any signs of debris or metal particles. Replace the filter if necessary.
  • Check for any leaks in the transmission system and repair them promptly.
  • Regularly monitor the fluid level and condition to ensure it remains clean and at the correct level.

By maintaining clean and uncontaminated transmission fluid, you can prevent potential damage and ensure optimal performance.

3. Belt and Pulley Issues

The Nissan CVT transmission utilizes a system of belts and pulleys to provide smooth gear ratios. Over time, these components may wear out or become misaligned, leading to transmission problems. Here’s how to address belt and pulley issues:

  • Inspect the belts for signs of fraying, wear, or stretching. Replace any worn belts with the appropriate replacements.
  • Check the pulleys for misalignment or damage. Properly align or replace any defective pulleys.
  • Ensure the tensioner is functioning correctly to maintain proper belt tension.
  • Regularly lubricate the pulleys and belts with recommended lubricants to minimize friction and wear.

By addressing belt and pulley issues proactively and performing regular maintenance, you can prevent major transmission failures.

4. Software Updates and Reprogramming

Nissan periodically releases software updates and reprogramming fixes for their CVT transmissions. These updates address known issues and improve transmission performance. Here’s how to update and reprogram the Nissan CVT transmission:

  • Visit a certified Nissan dealership or a reputable mechanic equipped with the necessary software update tools.
  • Have them check for any available updates and reprogram the transmission control module (TCM) if needed.
  • Ensure all updates and reprogramming are performed according to Nissan’s guidelines.

Regular software updates and reprogramming can resolve many common CVT transmission issues and improve overall performance.


Repairing a Nissan CVT transmission requires a combination of diagnostic expertise and mechanical skills. By accurately diagnosing the problem, addressing common issues like overheating, fluid contamination, belt and pulley problems, and staying vigilant with software updates, you can extend the lifespan of your CVT transmission. However, it is always recommended to consult with a professional mechanic or a certified Nissan dealership for complex repairs or if you’re unsure about any step in the repair process. Preventive maintenance and regular servicing are crucial for the long-term health and performance of your Nissan CVT transmission.
