What is the reason for the Chery Karry K50 disengaging in fifth gear while driving?

Chery K50 transmission disengaging in fifth gear, it is recommended to check the vehicle's transmission shift cable. Inadequate transmission calibration: If the fifth gear of the transmission is not properly calibrated, and the meshing position of the driving gear and driven gear is incorrect, it can cause severe deformation of the driving and driven gears. This changes the meshing angle of the gears, leading to separation of the driving and driven gears during vehicle acceleration! This results in the disengagement phenomenon. Poor quality of transmission components: If the materials used for transmission components and the quenching treatment quality are poor, and the quenching process for transmission shafts, driving gears, driven gears, and bearings does not meet standards, it can accelerate wear on the gears and bearings. Even if the quenching process for these components meets standards, substandard materials will not be durable.
Recently, I've repaired quite a few Chery Karry K50s, and the fifth gear popping out is quite a headache. I reckon it's mainly due to the synchronizer aging – over time, it wears thin and can't grip the gear teeth properly, causing the gear to jump out while driving at high speeds. The shift fork is another issue; if it's bent or stuck, it won't hold the fifth gear securely. Gear wear shouldn't be ignored either – if the gear teeth tips are worn down, they're prone to disengaging. Driving habits also play a role; if the clutch isn't fully depressed when shifting, forcing it in a semi-engaged state will definitely cause the gear to pop out. Last time I worked on a car, even a loose shift lever assembly ball joint caused this problem. Delaying repairs could damage the entire gear set. If you encounter this issue, get the synchronizer clearance and shift fork linkage checked immediately – trying to save a little now might cost you big later.
