When shifts turn harsh, late or don't happen at all, a failing solenoid may be the cause. The Pioneer Automotive Industries Transmission Shift Solenoid, part number 771077, is built to replace it. It is a direct-fit replacement for the 1993-1997 Ford Probe, 1993-2002 Mazda 626, 1995-2002 Mazda Millenia and 2000-2001 Mazda MPV. See the Buyer's Guide tab for engine-level details.
A shift solenoid is an electrically operated valve. The vehicle's control module switches it on and off to direct transmission fluid through the valve body, and that is how the automatic transmission selects each gear.
Signs that this automatic transmission shift solenoid may need replacing include harsh or delayed shifts, missed upshifts or downshifts, a transmission that stays in one gear, or a check engine light with a shift-solenoid trouble code. The same symptoms can also come from low or degraded fluid, wiring faults or other internal problems, so diagnose the cause before replacing the solenoid. Consult the vehicle service information for access and installation steps.
