How to distinguish between Nissan CVT7 and CVT8?
4 Answers
Nissan CVT7 and CVT8 can be distinguished by their transmissions. 1. Technical features of CVT7 transmission: Utilizes a sub-transmission. The most notable feature of Nissan's CVT7 transmission, which entered mass production in 2009, is that it was the first in the world to adopt sub-transmission technology. 2. Technical features of CVT8 transmission: CVT7 is mainly used in models with engine displacements below 2.0L, while CVT8, currently equipped in the new-generation Teana, is primarily used in models with engine displacements ranging from 2.0L to 3.5L. It is also Nissan's latest generation of CVT product. Relevant information about transmissions is as follows: 1. Introduction: A device that changes the speed ratio and direction of motion. It is used to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a housing and several pairs of gears. 2. Function: During vehicle operation, to adapt to different working conditions, the driving force and speed of the car need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the need for a transmission.
To distinguish between Nissan's CVT7 and CVT8 transmissions, I think we can start with the technical details. The CVT7 is typically used in older models like the Tiida or Qashqai, with transmission numbers usually starting with CVT007. It has a simpler appearance and a smaller housing size. The CVT8 is used in newer models such as the Sylphy or X-Trail, with numbers beginning with CVT008, and features upgraded internal pulley designs for smoother shifting. To identify them, you need to open the hood and locate the transmission label near the right front wheel, where a metal plate displays the model number. Alternatively, check the VIN code—the seventh digit corresponds to the year: models before 2015 mostly use CVT7, while those after 2017 generally use CVT8. This is crucial for maintenance, as CVT8 requires different fluid types, and using the wrong one can shorten its lifespan. I've seen many owners make mistakes and waste money.
Having driven Nissan cars for ten years, I can tell the difference just by the driving feel. The CVT7 has a bit of jerkiness when starting at low speeds, like a slight lurch when stepping on the accelerator; the CVT8 is much smoother, especially in stop-and-go traffic. The difference in fuel consumption is noticeable—the CVT7 can reach 9L/100km in city driving, while the CVT8 drops to around 7L. My new Altima, for example, has the CVT8, and I feel the engine responds faster with less humming noise. To confirm, I usually take it to a repair shop and scan it with a diagnostic tool to read the data. This gives me peace of mind in daily use, as the upgraded transmission improvements enhance the overall experience.
To check the model list, CVT7 is commonly found in older models like the 2014-2016 Qashqai, while CVT8 is used in post-2018 facelifted models such as the new Sylphy or T-Roc. When distinguishing, I first look at the model year and name—Nissan's official website or manual specifies which transmission is equipped. VIN code analysis is another method: specific positions in the code can reveal details, such as the ninth digit indicating the transmission version. Identifying this helps avoid buying the wrong parts, as CVT7 and CVT8 components differ, affecting maintenance plans. This is often useful when selecting used cars—I've helped friends check several times, and it's straightforward and practical.
