Solenoids are electro-hydraulic valves that control the flow of transmission fluid needed to change gears, opening and closing in response to the electrical signals they receive from your vehicle’s engine or transmission control unit, which pulls its data from a series of speed sensors in the engine. It is the flow of transmission fluid, which is controlled by the solenoid valves, that pressurizes your transmission’s clutches and bands, facilitating gear changes.
In automatic transmissions, transmission fluid is directed through the valve body by several types of solenoids, including:
Manual transmissions do not typically have shift solenoids. Instead, they use the manual clutch to control how and when gears shift.
The solenoid body itself is generally constructed from steel and designed in a cylindrical shape, with a valve and return spring. The solenoid coil consists of a wire wound around a conductive component that acts as an electromagnet. Though they vary in design, most transmission solenoids comprise the following nine parts:
If any of these parts fail, your solenoids stop working, and your transmission stops performing.
Common causes of transmission solenoid failure include:
If you suspect that one or more transmission solenoids have gone bad, get in touch with a Mister Transmission near you, and we will help you pinpoint and repair the problem, fast.
Plenty of transmission shifting problems can be traced back to a malfunctioning shift solenoid, including:
Depending on the make, model, and year of your vehicle, transmission solenoid replacement costs can vary. In general, a single faulty transmission solenoid replacement costs approximately $250. Replacing the entire solenoid pack can cost around $400.
As you can see, replacements are often costly, so you want to make sure that you do not replace a functional shift solenoid. To that end, we offer 100% free road tests and multi-check inspections to help you get to the root of the problem, maintain your vehicle’s performance for longer, and pay only for the services you need.
