Why can't the gear shift be moved from P position?
2 Answers
Automatic transmission P position locks the vehicle's gear shift. Below is relevant information about automatic transmissions: 1. The transmission has evolved from manual operation to automatic shifting: However, automatic transmission gears still have certain timing requirements. Improper operation (such as the automatic gear lever being stuck in P position) and forced gear shifting can easily damage the transmission. Let's look at how the automatic P position works: When the gear lever is in P position, the parking lock mechanism locks the transmission output shaft. In P position, the drive shaft is partially locked inside the transmission, so even without pressing the brake on flat ground, the vehicle still has some braking force. 2. Solution when the automatic gear lever is stuck in P position: To shift to other gears, first start the vehicle and then shift to other gears; or press the brake pedal before switching gears. When parking normally, always ensure the vehicle comes to a complete stop before shifting to P position, otherwise this situation of the gear lever being stuck in P position can easily occur.
I've been driving for over twenty years and have seen this kind of issue many times. The inability to move the gearshift from P is usually caused by a few common reasons. The most frequent one is that you're not pressing the brake pedal, or not pressing it firmly enough, because modern vehicles have a safety lock that only allows gear shifting when the brake is fully engaged. Another reason could be that the car hasn't come to a complete stop, and the transmission is still in operation—forcing the gearshift could damage internal components. Occasionally, it might be due to a brake system malfunction, such as a faulty brake light switch or a stuck solenoid valve. If you've tried pressing the brake harder and still can't move the gearshift, don't force it. Park in a safe location and have a professional mechanic inspect it to prevent further damage. To avoid such issues, make it a habit to come to a complete stop, press the brake firmly, and then shift gears when driving.
