What are the reasons for difficulty in engaging first gear in Jetta?

[DiRuby]

Jetta difficulty in engaging first gear may be caused by the following reasons: 1. Loose or severely worn shift fork, or even deformation: Loose screws fixing the shift fork can result in incomplete gear engagement. When the shift fork is severely worn, it cannot move the gear, causing difficulty in shifting. In this case, the damaged shift fork should be repaired or replaced, and the fixing screws should be tightened. 2. Wear of the positioning groove and positioning pin: The surface becomes irregular, sometimes jamming during gear shifting, preventing the positioning pin from sliding out of the groove, resulting in difficulty in engaging gears or shifting. This should be repaired. 3. Deformation of the shift shaft: This makes it difficult for the sliding gear to move. In this case, the shift shaft should be repaired or replaced. 4. Incomplete clutch disengagement: Even slipping may occur, causing the gears in the transmission to continue rotating during shifting, making it difficult to shift. In this case, the clutch should be adjusted.
