A transmission solenoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed.ransmission solenoids are usually installed in a transmission valve body, transmission control unit or transmission control module.
Transmission Solenoid: Function & Common Problems. While manual transmissions make use of the clutch to change gears, automatic transmissions rely on a complicated hydraulic system for shifting, and the transmission solenoid is especially important for this process.f the transmission solenoid is energized, the plunger opens and allows fluid to pass while a solenoid that is not receiving power is closed in its normal position. So while the various engine sensors determine when the gears should shift, it is the job of the transmission solenoid to act out the actual shifting.
