Help keep your automatic transmission shifting properly with the Pioneer Automotive Industries Transmission Control Solenoid 771123, an exact-fit replacement for a range of Ford, Mazda and Mercury vehicles. It fits many vehicles, among them the 1997-2001 Ford Explorer, 1997-2011 Ford Ranger and 2006-2010 Mazda B2300. See the Buyer's Guide tab for the full list and engine details.
This automatic transmission control solenoid is an electrically operated valve. The vehicle's control module switches it to direct the flow of transmission fluid inside the transmission, which helps manage shifting.
Signs that a transmission control solenoid may need replacing include harsh, delayed or erratic shifts, a transmission that stays in one gear, and a lit check engine light with stored transmission codes. Other faults can cause the same symptoms, so diagnose the transmission before you replace the solenoid.
