Dodge Coolway suddenly braked, and it seems that the gear can't be lowered.

1, the automatic transmission gear lever locking mechanism itself is faulty.

2. Brake light switch and circuit failure.

3. The throttle position sensor (throttle body assembly) is damaged, resulting in high idle signal voltage of the throttle position sensor. Need to contact the repair shop for repair as soon as possible to avoid accidents. The above is the reason why the sudden braking of Dodge Coolway can't seem to downshift and the solution.
