Possible reasons why the automatic transmission jams:
Low level or poor quality gear oil:
*Transmission oil provides lubrication and cooling to the internal components of the transmission.
*Low oil level or using the wrong type of oil can cause increased friction and overheating.
Mechanical faults:
* Worn solenoids, friction plates, or other components may prevent the transmission from operating properly.
*Damage to the housing or internal parts may also cause jamming.
Electrical faults:
* Problems with the wiring, sensors, or transmission control module can disrupt the signals needed for the transmission to operate properly.
* Faulty solenoids or sensors can cause unwanted shifting or jamming.
Software problems:
* Modern automatic transmissions are controlled by complex software.
* Bugs in the software may cause incorrect operation or jamming.
Other possible reasons:
*Overheating due to excessive load or slipping
* Contamination of the transmission oil with foreign substances such as metal shavings or coolant
*Transmission damage due to an accident
Actions to be taken in case of automatic transmission jamming:
* Stop the car in a safe place.
*Consult a qualified mechanic for diagnosis and repair.
* Do not attempt to force shift or tow a vehicle without proper equipment.
* When towing, you must place the vehicle in neutral or use the service mode, if available.
Consequences of a jammed automatic transmission:
* Damage to the internal gearbox mechanism
* Loss of vehicle controllability
* Increased risk of accident
* Significant repair costs
