Among the many complex moving parts involved in the shifting process of an automatic transmission are solenoids. Essentially, solenoids are electro-hydraulic valves that help facilitate gear changes in automatic transmissions. To gain a better understanding of the function and importance of transmission shift solenoids, consult this helpful guide.
The Function of Transmission Shift Solenoids
Solenoids control one or more gears in a transmission. The number of gears that a transmission shift solenoid controls will vary widely depending on the build of the car and the model of the transmission. When shifting gears, solenoids act as electro-hydraulic valves, which effectively control the flow of transmission fluid throughout the transmission.
Depending on the electric signals that they receive from the vehicle’s speed sensors and transmission control unit, the solenoids will open or close to direct the transmission fluid’s movement. As the solenoids open and close, the fluid pressure inside of the transmission will change, which facilitates gear shift.
The Importance of Transmission Shift Solenoids
As previously stated, transmission solenoids play an essential role in the process of shifting gears in an automatic transmission. If transmission solenoids become damaged, worn, or begin to fail, the vehicle will likely experience numerous shifting problems or lose the ability to shift gears altogether. Some of the most common issues associated with faulty shift solenoids include delayed shifting and an inability to downshift.
In addition, ineffective solenoids may prevent your transmission from shifting into the correct gear or may cause the transmission to shift erratically. Because such shifting issues could cause significant damage to your transmission and create highly dangerous driving conditions, it’s extremely important to contact a professional mechanic if you notice any symptoms of bad transmission solenoids.
If your transmission shift solenoids are damaged or worn beyond repair, don’t despair.
