If the automatic transmission is locked, here’s what you need to do:
1. Check the transmission fluid level:
*Low fluid levels can cause the transmission to slip and lock up.
* Check the fluid level on the dipstick (if equipped) and add fluid if necessary.
2. Disconnect the battery:
*This will reset the transmission’s electronic control unit (ECU), which may resolve some locking problems.
* Disconnect the negative terminal of the battery for a few minutes.
3. Move the gear shift lever to Park (P):
* This ensures that the transmission shaft is in neutral position.
4. Start the engine:
*Wait a few seconds while the engine is idling.
5. Connect the battery:
* Reconnect the negative terminal of the battery.
6. Try to move the gearbox:
* Slowly move the gear lever out of P and try shifting into other gears.
7. Check fault codes:
*If the transmission is still locked, connect the diagnostic tool and check for trouble codes. This may indicate the root cause of the problem.
8. Seek qualified help:
*If you cannot unlock the transmission yourself, please contact your auto repair shop for professional assistance.
Tips for preventing automatic transmission blocking:
* Change the transmission fluid and filter regularly.
* Avoid abrupt gear changes and forcing the gearbox.
*Check the fluid level every few months.
*Have the vehicle towed to a repair shop if there are any problems with shifting.
