Transmission solenoids are one of your automatic transmissions many critical components. A transmission solenoid is an electro-mechanical component valve used to control the flow of transmission fluid in the transmission, and they open and close as per the electrical signals they receive from your vehicles engine or transmission control unit, which pulls its data from a series of speed sensors in the engine.. Modern automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the cars computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. If one of these electro-mechanical valves fail, then all sorts of transmission problems can ensue..
