Understanding the Nissan Murano Transmission
The Nissan Murano has undergone significant evolution in its transmission technology since its inception. Each generation has brought advancements that enhance driving performance, fuel efficiency, and overall reliability.
Early Days: 4-Speed Automatic Transmission (2003-2007)
The first-generation Murano was equipped with a 4-speed automatic transmission. This gearbox was robust and reliable, offering smooth shifting that was standard for vehicles of that era. However, it presented limitations in fuel efficiency and responsiveness, particularly when compared to modern transmissions. Owners of this generation appreciated its reliability but often sought improvements, especially in terms of fuel economy.
The Rise of the Xtronic CVT (2008-2014)
With the introduction of the second generation, Nissan revolutionized the Murano’s driving experience by incorporating the Xtronic Continuously Variable Transmission (CVT). This innovative transmission eliminated traditional gear changes, providing a seamless driving experience. By maintaining a constant power flow, the CVT enhanced fuel efficiency and reduced engine noise, making it a significant upgrade over its predecessor.
Evolution of the CVT: Next-Generation Xtronic (2015-Present)
The third generation of the Murano saw further refinement in the CVT design. The next-generation Xtronic CVT offers improved responsiveness and smoother acceleration thanks to advanced software and a revised design. This transmission also includes a simulated gear-changing system that provides a more traditional driving feel when desired, ultimately catering to a broader range of driver preferences.
Common Transmission Problems in Nissan Murano
Despite its advancements, the Nissan Murano’s CVT has been associated with several common problems. Understanding these issues can help owners prevent or address them effectively.
Identifying Transmission Issues
Many Murano drivers report problems such as juddering, shaking, and hesitation during acceleration. These symptoms often stem from design flaws or reliability concerns inherent in the CVT. Regular maintenance and timely fluid changes can help mitigate these issues.
Addressing Transmission Problems
- Transmission Fluid Inspection: Regularly check the transmission fluid level and condition. Low or dirty fluid can lead to shifting issues and overheating.
- Throttle Position Sensors: Misaligned sensors can affect gear shifting. Regular diagnostics can help detect and rectify this issue early.
- Shift Solenoids: Malfunctioning solenoids can cause the transmission not to shift properly. Replacement may be necessary if identified as faulty.
