BMW 730 transmission temperature too high reasons are as follows: Engine and water temperature too high: Prolonged or overloaded engine operation can increase the coolant temperature, thereby affecting the transmission's heat dissipation; additionally, insufficient coolant in the radiator reduces the cooling system's effectiveness, leading to transmission overheating; Transmission clutch slipping: Clutch slipping generates additional heat, raising the transmission temperature and degrading the transmission oil quality, which in turn increases transmission wear; Thermostat stuck: If the transmission's thermostat is stuck, the oil inside the transmission cannot enter the cooling system, preventing the heat generated by the transmission from being cooled.

What does it mean when a car displays an icon of a car with a lock?

When a car displays an icon of a car with a lock, this symbol generally indicates that the anti-theft system is activated. The car anti-theft system is designed to prevent the theft of the vehicle itself or items inside the car. The car anti-theft system consists of an electronically controlled remote or key, an electronic control circuit, an alarm device, and an actuator. When the engine is in anti-theft mode, the car will not start. It is recommended that the owner take the car to a local dealer or repair shop to have the anti-theft system checked. To enhance anti-theft effectiveness, some cars are also equipped with a steering lock, which is used to lock the car's steering shaft. The steering lock is integrated with the ignition lock and is installed under the steering wheel, controlled by the key. That is, after the ignition lock cuts off the ignition circuit to stop the engine, turning the ignition key to the extreme left position will cause the lock tongue to extend and engage with the steering shaft groove, mechanically locking the car's steering shaft.
