Standard Ignition Automatic Transmission Kickdown Solenoid Switch P/N:SZ-1
Keep your automatic shifting the way it should with the Standard Ignition Overdrive Kick-Down Switch DS-3126 (also written DS3126). This electrical switch signals the transmission to kick down — commanding a downshift for passing and acceleration and managing the overdrive kickdown circuit. It drops in as a direct-fit replacement across a wide range of Ford and Lincoln trucks and vans, including the 1992-2001 Ford F-150, 1992-1996 Ford Bronco, 1997-2001 Ford Expedition, 1995-1998 Ford Windstar, 1992-2002 Ford E-250 Econoline, 2000-2001 and 2003-2005 Ford Excursion, and 1998-2001 Lincoln Navigator. See the Buyer's Guide tab for the full list of 33 applications.
Signs the original switch may need replacing include missed or erratic kickdown downshifts and no forced downshift when you press the pedal. Because those symptoms can have other causes, diagnose the circuit first; if a failed kick-down switch is the cause, this DS-3126 replaces it.
