What are the reasons for the jerking sensation in the Nissan X-Trail?

[PiperFitz]

During high-speed coasting deceleration, there is a noticeable occurrence and disappearance of engine braking, with the braking speed range maintained between 20~90 km/h. After the occurrence, there will be a subsequent jerk, and even after disappearance, there will still be some jerk. Absence of a one-way clutch leads to: Without discussing the durability of this transmission, even after upgrading the steel belt, it can still last over a hundred thousand kilometers, which is generally the mileage for most household vehicles. The key point is that the CVT lacks a one-way clutch, resulting in noticeable engine braking appearing and disappearing during high-speed coasting deceleration. Poor reliability and average durability: The CVT transmission is merely a simplified version of automatic transmissions designed to cut costs. Van Doorne's invention of this machine once had a hint of "corner-cutting," but in the European market, it was essentially a dead end from the start. This type of transmission, with its poor reliability, average durability, and compatibility only with low-torque engines, failed to gain acceptance among Europeans. It was later picked up by Japanese automakers, who were resource-constrained at the time.
