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 fluid is directed throughout the valve body by various transmission solenoidsâ such as the transmission shift solenoid, lockup solenoid, or transmission control solenoid (thereâs also a torque converter clutch solenoid) âthat either open or close hydraulic valves to regulate fluid flow.he transmission solenoid is responsible for opening or closing valves in the valve body to allow transmission fluid to enter, at which point the fluid can do its thing and pressurize the clutches and bands.
