What causes a Ford Focus not to move when shifted into reverse?

[SerenityDella]

Possible reasons include the gear not being fully engaged, the vehicle's handbrake not being released, or the synchronizer in the transmission being stuck. First, check if the gear is fully engaged. If there are no operational issues, it may require professional inspection. Eliminating operational errors: The first step is to check whether the gear is fully engaged. Many vehicles require pressing or lifting to engage reverse gear to avoid accidental shifting. If the gear cannot be engaged, check for any obstructions in the gear slot that may prevent shifting. Gear shifting faults: Fault-related issues could be due to a reverse gear oil leak, reverse and high gear clutch failure, or brake system problems. If encountering such issues, it is advisable to send the vehicle for immediate inspection to minimize transmission damage. Additionally, always ensure the vehicle is completely stopped before shifting into reverse to avoid vibrations after engaging reverse gear.
