<jats:title>Abstract</jats:title>
<jats:p>The evaluation index of loader shift quality was analysed, and the model of the evaluation index was established. The main causes of the shift impact of the transmission were analysed, and it was concluded that the disturbance caused by the torque of the transmission output shaft had a direct relationship with the oil filling and discharging rule in the clutch and the change in oil pressure. Based on theoretical analysis, an accurate control strategy of a proportional solenoid valve to realize electro-hydraulic proportional closed-loop buffering control was proposed. The buffer control of the transmission shift is performed by using this method. The effectiveness of the control strategy was verified by the experiment of the shift oil pressure. The shift impact of the transmission was reduced, and the loader shift quality was improved.</jats:p>
