Why can't the Chery A3 automatic transmission disengage?
2 Answers
The reasons and solutions for the Chery A3 automatic transmission not being able to disengage are as follows: Gear Lock: It may be due to gear lock, or not fully braking when parking, directly shifting into P gear, causing gear braking instead of brake braking. Solution: If the entire vehicle cannot power on and the automatic transmission is in protection mode, it also won't disengage. You can perform a gear unlock by pressing the black button above the transmission's P gear to unlock it. Precautions for shifting gears in automatic transmission vehicles: Generally, after stopping an automatic transmission vehicle, you should shift to P gear to prevent the vehicle from rolling away in neutral or being unable to remove the key when in drive gear. When you want to continue driving, you need to turn on the ignition and press the brake to shift gears. At this point, it's crucial that when you press the brake, the brake light switch activates, sending a signal to the computer, which then allows gear shifting.
I've encountered similar issues before, usually caused by a faulty or poorly connected brake switch. Since automatic transmission vehicles require the brake pedal to be pressed to shift gears, if the brake lights don't illuminate, it might indicate a switch failure or loose wiring. First, check if the brake lights are functioning properly. If they're not, replacing the switch or tightening the connections should solve the problem. Another possibility could be an issue with the shift lever lock. Many modern cars come with an anti-theft lock, and if the key isn't turned to the proper position or the battery is low, it might cause the gear to get stuck. Try turning the key to the ACC position or disconnecting the battery for a few minutes to reset the system. If the problem persists, the transmission control module might be malfunctioning, in which case you'll need to visit a professional workshop for a diagnostic scan with specialized equipment. Avoid forcing the gear shift during normal driving, as it can wear out components. Safety comes first—it's best to pull over immediately and address the issue. Regular maintenance of transmission fluid can help prevent such troubles; I recommend checking the electrical system every two years.
