No, it is not recommended to change gears in an automatic transmission (AT) with the engine turned off.
Reasons:
* Transmission damage: When the engine is turned off, the automatic transmission oil pump does not work and transmission fluid does not circulate. As a result, friction between metal components can cause damage.
* Wear of gear shift mechanisms: Gear shift mechanisms are designed to operate with oil pressure, which is absent when the engine is turned off.
*Transmission Lock: On some automatic transmission vehicles, the shift lever may be locked in the park (P) position when the engine is turned off. Forcibly shifting gears under such conditions may damage the locking mechanism.
Exceptions:
* Shifting to Neutral (N): In emergency situations, you can shift to Neutral (N) to move the vehicle with the engine off.
* Towing a vehicle: When towing a vehicle with an automatic transmission, some manufacturers recommend shifting to neutral (N) or towing mode (if equipped). Always follow the manufacturer’s instructions.
