What is a Transmission Solenoid? An automobile’s transmission is made up of a lot of complicated parts and one of those parts that play a key role in your car’s transmission is transmission solenoids. A transmission solenoid, also called a cylinoid, is an electrohydraulic valve that controls fluid flow in an automatic transmission. Transmission solenoids are usually installed in a transmission control unit, transmission value body or transmission control module. Solenoid valves control the flow of transmission fluid that pressurizes your car’s transmission bands and clutches. Solenoids are generally made from steel having a cylindrical shape with a value and return spring. Most transmission solenoids consist of several parts and if any of these parts fail, your transmission stops performing.

Types of Transmission Solenoids:

The average car has 4 types of solenoid valves. The Transmission Control Solenoid, The Transmission Shift Solenoid, The Torque Converter Clutch Solenoid and The Lock Up Solenoid.

Parts of Transmission Solenoids:

Most transmission solenoids are constructed with nine parts. These parts are Valve Body, Coil Winding, Lead Wires, Spring, Orifice, Piston, Inlet Port, Outlet Port, Solenoid Coil Body, and Orifice.

Causes of Transmission Solenoid Failure:


Electrical Issues-

Electrical issues can cause a transmission solenoid to fail. This could be caused by faulty wiring or shorts in your vehicle’s electrical system.

Dirty Fluid-

Transmission fluid can get dirty over time and is one of the leading causes of a bad shift solenoid. Dirty fluid may cause the solenoid to stay open or close.

Wear and Tear-

Like any component, solenoids simply wear out over time. Sand, dirt, and dust frequently work their way into solenoids and valves which increases the amount of wear and tear that occurs within the moving parts.
