When gear is engaged, the gear cannot be entered smoothly.

There maybe some reasons: (1) The pressure of the pressure valve is too low; (2) The hydraulic pump works poorly and the seal is not good; (3) The hydraulic pipeline is blocked; (4) The clutch sealing ring is damaged or leaked; (5) The gear lever is not in the right place. When the gearbox is automatically out of gear or in disorder. You need to check the positioning device of the shift control valve. The main reason for the failure is the serious wear of the positioning steel ball or the failure of the spring; (2) Due to long-term use of the shifting joystick, the position and length of the lever have changed, and the ratio of the levers is not accurate, causing deviations in the operating position and causing misalignment.
