Function of transmission control
The transmission control unit controls the automatic transmission of a vehicle by processing signals from the engine and the transmission. It uses this data and stored learning values to calculate the optimum gear and the pressure required to change gear, as well as the torque currently being transmitted. In addition, the automatic selector lever allows the driver to select the gear manually.
This selection is signaled to the EGS control unit and implemented. Gearshift paddles complement the manual gearshift lever on manually shiftable automatic transmissions, automated manual transmissions and dual-clutch transmissions. They enable gears to be shifted up and down by pulling the corresponding rocker.
