Keep your automatic transmission shifting the way the factory intended with the Standard Ignition Automatic Transmission Control Solenoid TCS31. This transmission control solenoid drops in for a wide range of 1995-1997 Ford, Lincoln and Mercury applications — including the Ford Crown Victoria, F-150, F-250, Mustang and Thunderbird, the 1997 Ford Expedition, the Lincoln Mark VIII and Town Car, and the Mercury Cougar and Grand Marquis (see the Buyer's Guide tab for the full list). A control solenoid regulates the flow of transmission fluid within the valve body to command gear changes; if a failed solenoid is the cause of harsh shifts, slipping, or a solenoid trouble code, this replaces it.

  • Industrial-grade materials: built from metal and plastic with professional construction for reliable service.
  • Direct bolt-on: mounts with a single mounting hole and includes gasket(s); no wiring harness, mounting bracket, or hardware included.
  • Ready-to-wire connector: one rectangular female connector with two male blade terminals.
  • Made in the United States.

Diagnose the cause of the shifting concern before replacing, as other components can produce similar symptoms.
