Transmission jump gear is the car in the driving speed shift lever automatically jump back to the neutral position, this phenomenon occurs in the high-speed, sudden changes in load or car by severe vibration, and most of the gear shift in the high gear. So what is the reason for the gearshift? How to eliminate this failure?

Cause of transmission shift failure:

L, variable speed gears, gears or synchronizers Cone wheel wear teeth, along the tooth length to form a prototype, when engaged in an axial thrust, in the work by shaking, speed changes in inertia, forced meshing gear In the axial direction.

2, North Ben v3 accessories variable speed bending deformation, excessive wear, loose screw or variable speed bar deformation, so that the gear can not be properly engaged.

3, self-locking device wear loose, spring elasticity or break, resulting in insufficient locking force, so that the fork can not be reliable positioning.

4, shaft and bearing wear serious, axial clearance is too large, or the first and second axis and the intermediate shaft is not parallel, so that the gear can not normally engage and swing up and down.

5, the shaft of the spline teeth and sliding gear spline groove wear excessive.

6, the second axis spline distortion or key tooth wear too much, lock the nut loose caused by shaft or gear before and after the movement.

7, North Ben v3 accessories synchronizer lock pin loose, synchronizer stuck or joint tooth length direction has been serious wear and tear.

8, North Ben v3 accessories transmission fixed is not strong.
