What is the reason why the Baojun 730 suddenly cannot shift gears while running?

[DelMaggie]

Here are the specific reasons why the Baojun 730 cannot shift gears: 1. Failure of the P-gear locking solenoid valve. For safety reasons, to prevent the vehicle from accidentally shifting into other gears when starting, there is a P-gear solenoid valve that needs to receive the signal from the brake pedal to release. These two components are related, and if either one fails, it will prevent the gear lever from being pushed out of the P-gear and shifting into other gears. 2. Internal failure of the gear lever assembly. The internal gears of the gear lever are worn out, causing the gear lever to get stuck and making it difficult to pull forward or backward, resulting in the inability to shift gears or difficulty in shifting. 3. Incomplete clutch disengagement. This may be caused by failure of the clutch disc and clutch pressure plate, requiring replacement of the clutch three-piece set: friction disc, pressure plate, and release bearing. 4. Debris in the transmission oil affecting the gear shifting of manual transmission cars.
