Why can't an automatic transmission car shift gears?
1 Answers
An automatic transmission car may fail to shift gears due to reasons such as low vehicle temperature. Below are the reasons and solutions for an automatic transmission car failing to shift gears: 1. Reasons: Low vehicle temperature, the transmission oil is not fully lubricated. Difficulty shifting into first gear while moving is due to a mismatch between vehicle speed and gear. First gear and reverse gear lack a synchronizer. 2. Solutions: Try shifting into reverse gear while the vehicle is stationary. If the transmission makes a "clicking" gear collision sound during the process, it indicates that the vehicle's clutch is not fully disengaged. After repairing the clutch, the issue can be resolved. If reverse gear engages smoothly but first gear is difficult to shift into, it is recommended to visit a specialized repair shop to replace the transmission oil, and the issue can also be resolved.
