Automatic transmission
At the request of the client, BMW models can be equipped with an automatic transmission. The automatic transmission provides, depending on the design, automatic shifting in four or five forward gear ranges.
The automatic transmission shift points are controlled by an electronic-hydraulic system (so-called "EN"-control). This means that the hydraulic system of the automatic transmission is controlled by an electronic control unit that determines the right transmission shift points depending on the speed and load of the engine. The driver can call up three different programs depending on the condition of the road surface ("Economy", "Sport", and "Winter program").
Information about the temperature of the oil in the box is also supplied to the control unit from a special sensor. When the gearbox and engine are cold, shift torques are increased, resulting in increased shift comfort in the warm-up phase. In addition, increased engine speeds result in faster warm-up, and therefore reduced emissions of harmful substances into the atmosphere.
Another advantage of the control system is fault diagnosis: Faults that occur are recognized and stored in the control unit. Stored faults can be interrogated and rectified in a targeted manner at a BMW workshop. If there are no important information signals at the input, the control unit switches to the emergency program, but at the same time, there are shortcomings in the behavior of the car.
A condition for being able to assess the operation of an automatic transmission and troubleshooting is the presence of sufficient professional experience, therefore, if you suspect an abnormal operation of an automatic transmission, you should immediately contact a service station. In chapter "Maintenance" only a description of simple tests is given.
