What to Do When an Automatic Transmission Vehicle Suddenly Stops Moving While Reversing?

[StAutumn]

Automatic transmission vehicles may stop moving while reversing due to the following reasons: Accidental Press of the Auto Hold Button: Enabling this function enhances safety when waiting at traffic lights or crossing pedestrian crossings by preventing the vehicle from moving without throttle input. Releasing the auto hold function allows the vehicle to move forward or reverse upon brake release. Electronic Parking Brake Not Released or Improper Gear Engagement: If the electronic parking brake is not released or the gear is not properly engaged, the reverse gear may not function. Releasing the electronic parking brake and adjusting the gear engagement method can resolve this issue. Transmission Issues: Internal transmission malfunctions may occur. First, check if the transmission fluid level is too low and whether the main oil pressure and gear oil pressure are normal. Then, verify if the gear position switch signal is normal, if the wiring from the transmission computer to the shift solenoid valve is intact, and if the gear solenoid valve is functioning properly. If no issues are found, it indicates a problem with the internal control system of the transmission, requiring disassembly to inspect internal components.
