2006 Ford Fusion Shift Solenoid. A single shift solenoid’s replacement cost is between $100 and $350 and a shift solenoid pack costs between $400 and $700, including transmission fluid, filter, parts, and labor work. Dirty fluids sometimes cause a shift solenoid to become stuck in the open or closed position.

Most of the key trapped. Shift solenoid valve 'e' is turned on or off by the transmission control module (tcm) in response to signals sent from the park/neutral position (pnp) switch, vehicle speed and engine control module ( ecm) (throttle opening). If the solenoid is stuck, fluid can’t enter the transmission valve body and pressurize the appropriate gear.
