The hesitation issue with the Dongfeng Nissan X-Trail's CVT may stem from the desynchronization between engine RPM and clutch disc RPM.
This situation arises when the transmission speed fails to increase promptly, causing the upshift speed to lag behind the driver’s acceleration request, thus resulting in a momentary hesitation during gear shifts.
When the driver releases the throttle or applies the brake, the energy recovery system engages immediately, prompting the generator to catch up with the engine. This operation can impose additional strain on the engine, further affecting the synchronization between engine RPM and clutch disc RPM, exacerbating the hesitation sensation.
Many owners experience this phenomenon at low speeds, particularly when frequently shifting between first and second gears, where the clutch’s engagement and disengagement cannot effectively transmit power, leading to common low-speed hesitation. For owners, it is advisable to consider whether this sensation falls within the normal range.
Generally, if the hesitation persists, it may be deemed normal; however, if a sudden change occurs, it should be taken seriously. Additionally, owners should check the transmission temperature to ensure normal operation. If abnormalities are detected, the cooling system should be examined for issues. Other viable solutions include reprogramming the gear box computer system, regularly changing the transmission fluid (recommended every two years or every 40,000 kilometers), and inspecting the valve body for damage.
