The invention discloses a gear shifting control method, device and system, a controller and a storage medium, and aims to solve the technical problem of power interruption in the gear shifting process in an existing gear bypassing scheme. The method comprises the steps that when it is detected that a downshift demand of sliding from a current gear to a first gear exists, oil is filled into an odd-number shaft clutch corresponding to a second gear; the input torque of the transmission is converted from an even-numbered shaft to an odd-numbered shaft; the rotating speed of the engine is controlled to be increased from the clutch rotating speed corresponding to the current gear to the clutch rotating speed corresponding to the second gear, and oil unloading is conducted on even clutches; after oil unloading of the even clutch is completed, the first gear is controlled for shifting fork gear engaging; after shifting fork gear engaging is completed at the first gear, the even number of clutches are filled with oil
