Transmission not shifted into P gear means that the transmission was not shifted into P gear when the car was parked last time. Now, to start the car, the transmission must be shifted into P gear to start the engine. If the transmission is not shifted into P gear, the engine cannot be started. This is a safety feature set by automatic transmission cars to protect the driver's safety. The P gear is the parking gear, which has an internal locking mechanism. Only when the gear is shifted to P gear can the car key be pulled out, which is equivalent to forcing the driver to ensure that the vehicle is parked stably before leaving with the key. This design is to ensure safety. The P gear is a gear specially used for parking and long-term stopping in automatic transmission cars. Its nature is equivalent to neutral gear. It is a special neutral gear that mechanically locks the output shaft of the transmission to achieve the purpose of fixing the vehicle. Its function is to brake after parking to prevent the vehicle from moving.
