Keep your automatic transmission shifting on command with the Standard Ignition Automatic Transmission Control Solenoid (MPN TCS31). This electro-hydraulic solenoid controls the flow of transmission fluid within the valve body, translating signals from the powertrain control module into the pressure and shift actions the transmission needs. It installs as a direct-fit replacement for the 1995-1997 Ford F-150, F-250, Mustang, Crown Victoria and E-150 Econoline; the 1997 Ford E-150 Econoline Club Wagon, E-250 Econoline and Expedition; the 1995-1997 Ford Thunderbird; the 1995-1997 Lincoln Mark VIII and Town Car; and the 1995-1997 Mercury Cougar and Grand Marquis, plus the 1997 Mercury Mountaineer. See the Buyer's Guide tab for engine-level fitment details.
