Common transmission repairs and problems with solenoids.

A solenoid in an automobile’s automatic transmission is a hydraulic valve powered electronically and regulates how much fluid flows throughout the automatic transmission. This is an integral part the hydraulic system that performs shift functions. In an automatic transmission bands and clutches do the shifting applied by fluid pressure.

A solenoid is basically a plunger that is spring loaded and wrapped with a coil of wire. The engine sensors evaluate the information provided by the movement of the vehicle and the ECU (Engine Control Unit) or TCM (Transmission Control Unit) makes the shifting up or down by signaling the several solenoids to perform their function.

When your solenoid malfunctions, here are the symptoms you may discover.

• Malfunctioning Shifting - The transmission will miss a gear, get stuck in gear or shift erratically.
• Transmission Won’t Shift - If the solenoid gets stuck you will not be able to shift.
• Transmission Disengaged - Lack of proper current to the solenoid or if you have old fluid it will cause the solenoid will get stuck causing it to take a while to engage.
