What Causes an Automatic Transmission to Fail to Engage Gear?

[LincolnAnn]

Automatic transmission failing to engage gear can be caused by: gear lock engaged, car battery drained, or onboard computer malfunction. Gear lock engaged: Some automatic vehicles are equipped with a gear lock switch, primarily used to force gear shifting when the car has no power or to prevent rolling. It's possible the driver accidentally activated this switch, locking the gear. Solution: Locate the "shiftlock" button near the gear lever to unlock. Car battery drained: A depleted car battery can also prevent gear engagement. Check if the vehicle's lights and dashboard are functioning normally. If not, it indicates the battery is drained. Solution: Simply recharge the battery. Onboard computer malfunction: Temporary disruption in the onboard computer may occur. Try restarting the vehicle to see if gear shifting resumes. A broken gear cable can also prevent gear shifting. Solution: Replace the gear cable.
