What are the repair methods for the old Jetta not engaging reverse gear?

[Brown]

Repair methods for not engaging reverse gear are as follows: 1. Adjust the free travel and total travel of the clutch pedal; Bleed the hydraulic control system; adjust the hydraulic control system, repair the clutch; 2. Adjust the external shift mechanism of the transmission: Eliminate jamming, remove foreign objects, and ensure the shift lever operates accurately; 3. Inspect and repair the transmission's control mechanism: Replace or repair damaged shift forks and shift fork guides. Reasons for not engaging reverse gear are as follows: 1. Clutch: If you find it difficult to engage reverse gear, it might be because the clutch is not fully depressed. In this case, simply press the clutch again. 2. Gear Position: If the clutch is fully depressed and reverse gear still cannot be engaged, it might be due to the gear teeth being misaligned. Since many car models do not have synchronizers for reverse gear, there is a chance that the gear teeth are misaligned when you try to engage reverse, preventing it from engaging. The solution is simple: shift into 1st, 2nd, or 3rd gear to rotate the gears slightly, then try engaging reverse again.
