What is an automatic transmission solenoid??

May 19th, 2009

An automatic transmission solenoid is simply a solenoid. A solenoid is an electrical device that opens and closes by getting a command from the computer in your car. Of course the computer gets many signals from other inputs all over the car, in order to make a decision.

What then is a solenoid?? Here is cool demo using water:

Solenoids are somewhat more complicated than that and operate many sophisticated devices on your car. They also are inside your transmission. Solenoids come in multiples and sometimes they are a ‘solenoid block’ assembly pack. These assemblies carry as many as 8 solenoids on certain transmissions. The solenoids bath in automatic transmission fluid.

It is easy to see how a fully operational electrical system is imperative in how a fully computerized car performs. System is the key word here. The electrical system is so sensitive that a loose or worn gas cap can cause serious driveability problems. The computer detects a vacuum leak at the gas cap, it therefore sends a false signal to the engine that it is starving for gas, which causes a loss of performance and gas mileage.

Every remanufactured transmission GotTransmissions.com sells had new OEM solenoids.
