If you turn off the engine with the automatic transmission engaged, the following consequences may occur:
* Damage to the automatic transmission: The rotating engine flywheel provides the automatic transmission oil pressure necessary to shift gears and lubricate components. When the engine shuts down, pressure drops, which can damage gears, bearings and other parts.
* Increased transmission load: Without a running engine, the automatic transmission can no longer absorb vibrations and shocks from the transmission and differential, which can lead to premature wear and damage to these components.
* Slipping or hard shifting: When restarting the engine, slipping or hard shifting may occur as the automatic transmission attempts to restore oil pressure and engage the gears correctly.
* Overheating: If the engine is turned off for an extended period of time, the automatic transmission may overheat, especially in hot conditions. This can damage seals and friction elements.
Using the neutral function:
To avoid these problems, it is recommended to place the automatic transmission shift lever in the neutral (N) position before turning off the engine. This disconnects the transmission from the engine, allowing oil to continue to circulate and protecting critical components.
