What Causes Difficulty in Shifting Gears in a Transmission?

[DiJack]

The reasons for difficulty in shifting gears in a transmission are as follows: 1. It may be caused by poor performance of the synchronizer, and it is also necessary to check the clutch plate and clutch travel. 2. The shift fork is loose or severely worn or even deformed. The screw fixing the shift fork is loose, resulting in incomplete gear engagement. After severe wear of the shift fork, it cannot move the gear, causing difficulty in shifting. 3. Wear of the positioning groove and positioning pin. The surface presents irregular steps, sometimes getting stuck during gear shifting, and the positioning pin cannot slide out of the groove, resulting in failure to engage the gear or difficulty in shifting. 4. Deformation of the shift shaft makes it difficult for the sliding gear to move.
