What is the reason for the noticeable gearshift jerkiness in the Volvo XC60?

Volvo XC60 gearshift jerkiness is caused by the characteristics of the dual-clutch transmission. The specific reasons and the hazards of the jerkiness are as follows: Specific reasons: Because the Volvo XC60 is equipped with a dual-clutch transmission, the characteristic of a dual-clutch transmission is that the gearshift jerkiness is more noticeable at low speeds. Moreover, prolonged low-speed driving can easily cause the transmission to overheat, and once the transmission overheats, it is prone to shaking. Hazards of jerkiness: Transmission jerkiness is the impact sensation generated by the inertia of the moving parts inside the engine. During the process of the engine speed being either increased or decreased, if not handled properly, causing sudden changes in engine speed during gear shifts, the inertia of the moving parts inside the engine will react against the vehicle body.
My Volvo XC60 also experienced transmission jerking a while ago, especially during low-speed gear shifts where it felt like it was stuttering. The main reason might be due to aging transmission fluid or insufficient fluid level, as deteriorated fluid can affect lubrication, leading to rough gear shifts. If the fluid hasn't been changed for too long—typically, it should be replaced every 60,000 kilometers—the buildup of contaminants can worsen the issue. Sometimes, the control module's software also needs updates, as system bugs can cause inaccurate shift timing. On the hardware side, clutch wear or sensor failures can also trigger jerking. I’ve found that a thorough inspection during regular maintenance can prevent such problems, like having the shop check the fluid condition. Aggressive acceleration while driving can exacerbate the symptoms, so trying a smoother driving habit might help.
