To Solve The Problem Of Random Blocking, Do The Following 4 Points

①When the driver manipulates the shift lever, he should follow the normal requirements. If the lever is deformed, it should be updated, corrected or even replaced in time.

②If two gears can be engaged at the same time, it means that the interlock mechanism is invalid and should be repaired or replaced in time.

③ If the gear cannot be changed in the gear position, or if the range of the joystick position changes is slightly smaller, a gear will be hung, which means that the groove or the groove of the shift fork that the steel ball at the lower end of the joystick matches with is seriously worn. The defective parts should be replaced in time.

④ The key and gear of the fixed gear should be replaced in time, the positioning spring should be replaced, and the interlocking device should be used to correct the problem of simultaneously engaging two gears and automatically engaging the gear.
