The one component of the entire system that’s critical to all of these parts working properly together is the Automatic Transmission Fluid, or ATF. Finally, the Mechatronics is the “brain” of the transmission, a complex system of ports, valves and electronics that control all transmission functions. It uses two turbines which spin independently, but which are fluid coupled allowing the engine to idle while the engine is stopped and produce smoother acceleration as it shifts through the gears. The Torque Converter connects the transmission to the engine and multiplies the torque during initial acceleration. Clutches or “clutch packs” engage and disengage the gear sets. The planetary gear sets provide the chosen gear ratios for the vehicle. The pump supplies pressurized transmission fluid for many uses throughout the unit. There are several main components that make up the step-type transmission. The Dual Clutch Transmission (or DCT), the Continuously Variable Transmission (or CVT) and the step-type transmission which is the most common, especially here in the US. There are 3 basic types of automatic transmissions found throughout the world. The automatic transmission combines electrical & mechanical systems, hydraulics and computer processors to smoothly shift through the gears and transfer engine power to the drive wheels. In fact, the automatic transmission is perhaps the most complicated mechanical component in an automobile. Automatic transmissions are now more complex than ever, placing ever-greater demands on auto transmission fluids.
