Yes, the automatic transmission may seize the engine in the following cases:
* Transmission shaft failure: If the transmission shaft in an automatic transmission breaks, it can jam the engine because the transmission will not be able to disengage.
* Seized transmission pump: If the transmission pump seizes, it can block the flow of transmission fluid, leading to increased friction and potential engine seizure.
* Torque Converter Damage: This can cause the engine to seize if the damage causes the transmission to lock up.
* Overheating of the automatic transmission: Excessive overheating can cause the internal components of the automatic transmission to expand, which can cause friction and engine seizure.
* Mechanical damage: Severe mechanical damage to the automatic transmission, such as broken gears or bearing failure, can lead to engine seizure.
