What's the reason why the Changan CS35 can't shift gears?

Introduction to the reasons why the Changan CS35 can't shift gears: 1. Clutch cable failure: Some manual transmission cars still use cables to control the clutch. The outer skin of the cable is prone to cracking, resulting in difficulty shifting gears without the clutch. Simply replace the cable. 2. Excessive gear self-locking force on the clutch side: This makes it difficult to engage and disengage gears. In this case, it is recommended to go to a repair shop to adjust the clutch cable and gear stop lock. 3. Clutch master cylinder failure: The clutch hydraulic master cylinder may experience pressure loss or oil leakage during use, causing difficulty in shifting gears when pressing the clutch. It is necessary to go to a repair station to replace the clutch master cylinder, and after replacement, an air bleeding operation must be performed. 4. Transmission failure: For example, insufficient transmission fluid, stuck transmission shift mechanism, or failure of a certain gear or shift fork, all of which may cause difficulty in shifting gears or inability to engage gears. For transmission problems, it is necessary to go to a professional repair shop for a detailed inspection.
