The automatic transmission solenoid helps maintain the flow of transmission fluid and operates with the engine sensor to switch gear speeds. It kind of functions similar to the clutch in a manual transmission.
Automatic transmission solenoid functionThe vehicle's transmission functions by small valves also known as solenoids. These valves regulate the flow of the transmission fluid inside the transmission system by opening and closing when the signal is sent electrically. The signal can be transmitted by the engine, sensors, or the transmission control unit. Solenoids are crucial to automatic transmission systems because they make sure that the automation of gear shifting is quick and precise.
Common issues with a bad automatic transmission solenoid functionA bad automatic transmission solenoid may not shift out of neutral, the shifts can be rough, and the ride quality will be poor.
