Common transmission repairs and problems with solenoids.

A solenoid in a vehicle's automatic transmission is a hydraulic valve powered electronically and regulates how much fluid flows throughout an automatic transmission. This is an integral part the hydraulic system that performs shift functions in an automatic transmission unlike a manual transmission which uses a clutch to shift gears. 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 speed and engine sensors evaluate the information provided by the movement of the car and the ECU (Engine Control Unti) 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 will discover as the operator of the vehicle.

• Malfunctioning Shifting - You will notice your car or truck will miss a gear, get stuck in gear or shift erratically.
• Transmission Will Not Shift - If the solenoids get stuck in position 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 the solenoid will get stuck and shifting will not function causing it to take awhile to shift or not engage.
