The automatic transmission’s primary responsibility is to allow the engine to operate in a narrow speed range while providing a wide spectrum of output speeds. Basically, your transmission is in charge of shifting from gear to gear. Today, automatic transmissions are electronically controlled. They operate by using an extensive system of switches, solenoids and sensors. A properly functioning transmission will relay data between the computer and the transmission system.
Generally, symptoms of a failing transmission system can include: fluid leaks, warning lights, irregular noises when changing gears, lack of movement and odd smells. Keep in mind that these symptoms are not inclusive, there could be other signs that indicate a transmission in need of repair. If you suspect your transmission might be failing, it is important to get it diagnosed as soon as possible.
