What are the reasons for the 2016 Changan Eado automatic transmission not being able to shift gears?

[ElizabethMarie]

Here are the reasons why the 2016 Changan Eado automatic transmission cannot shift gears: 1. When parking on a slope, the shift lever was not correctly placed in the P position: A torque lock phenomenon may occur. The P position torque lock phenomenon is a normal occurrence. When the vehicle's weight exerts excessive force on the transmission and parking pawl, the parking pawl and parking gear generate greater friction, making it difficult to move out of the P position and accompanied by a certain impact force. 2. The shift mechanism's P position lock cannot execute the unlocking due to a system failure: Common reasons include damage to the shift mechanism, failure of the brake light switch, or issues with the wiring or controller. In this case, direct shifting is not possible, and only emergency methods can be used.
