What causes the inability to shift gears in the Changan BenBen IMT automatic transmission?

[JanelleLynn]

Sensor malfunction. Below are the detailed explanations: 1. Lack of maintenance over the years: The vehicle does not move when shifting gears, the dashboard can display normally when shifting to D or R gear, and the computer diagnostic tool shows a clutch malfunction. After removing the air filter box and repeating the usual ignition steps, it is observed that the electric clutch can only extend but not retract. Such malfunctions often occur in older vehicles with high mileage, which is a problem of prolonged lack of maintenance and premature clutch wear. It is necessary to replace the transmission clutch kit and the three plastic gears inside the clutch. 2. Electronic clutch: The vehicle does not move when shifting gears, the dashboard cannot display normally when shifting to D or R gear, which could be due to a short circuit, sensor malfunction, damaged gear lever, or electronic clutch failure. First, check whether the gear lever, transmission, actuator circuit, and fuse are functioning properly.
