Keep automatic transmission problems at bay with a new transmission shift solenoid from AutoZone. A bad solenoid cannot effectively control the flow of transmission fluid, causing delays and unexpected friction or disconnection between the shift gears. AutoZone sells transmission solenoids from brands you can depend on, like ACDelco, Dacco, Dorman, and Duralast. Buy the parts you need to keep your vehicle shifting smoothly and get free next day delivery or same day in-store pick pick up.

The shift solenoid is responsible for controlling the flow of transmission fluid. Responding to electrical signals sent by the Engine Control Unit (ECU), or the Transmission Control Unit (TCM), the solenoid pack opens and closes valves, allowing the fluid to flow into the transmission valve body. The fluid pressurizes the clutches and bands so your vehicle can switch gears.

The signals sent to the solenoid pack are based on information collected by engine and vehicle speed sensors to maximize your engine’s efficiency. This data is analyzed by either the ECU or TCM, depending on what your vehicle is equipped with. The ECU uses the ground circuit to control the solenoid’s plunger, while the TCU can directly control the solenoid pack with a 12v signal.

If your check engine light is on and your vehicle won’t shift as smoothly as it used to, it’s likely time for a new solenoid pack. Put an end to shifting delays with our lineup of transmission solenoids that were specially engineered to meet or exceed OE performance for your vehicle.
