Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high pressures and temperatures.
Automatic transmission solenoid is located inside the transmission. The automatic control solenoid is part of a unit called the solenoid pack that functions like a sensor signaling the engine by adding or alleviating the hydraulic pressure of the system.This allows you to shift between gears smoothly.he transmission is an automotive part located at the back of the engine and allows the vehicle to move based on its ability to shift gears. The shifting of gears is made possible the automatic transmissions solenoid.
Next, is the solenoid pack. The 4R100 uses a housing containing five solenoids and a temperature sensor. Depending on the cause of falure and the miles on the transmission you may or may not replace this part. If you have over 100,000 miles on your transmission it's a good idea to include this.
