A TCU generallyuses sensors from the vehicle as well as data provided by the engine controlunit (ECU) to calculate how and when to change gears in the vehicle for optimumperformance, fuel economy and shift quality.   Electronic automatic transmissions havebeen changing in design from purely hydromechanical controls to electroniccontrols since the late 1980s. Since then, development has been iterative andtoday designs exist from several stages of electronic automatic transmissioncontrol development. Transmission solenoids are a key component to thesecontrol units.   The evolution of the modern automatictransmission and the integration of electronic controls have allowed greatprogress in recent years. The modern automatic transmission is now able toachieve better fuel economy, reduced engine emissions, greater shift systemreliability, improved shift feel, improved shift speed and improved vehicle handling.The immense range of programmability offered by a TCU allows the modernautomatic transmission to be used with appropriate transmission characteristicsfor each
