Gear Shift Control
WARNING: This page is about a different car, the 2006 Mercury Montego and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
When the shift lever is moved from N to D or from N to R, after the engine is started, a shift control solenoid assembly (SSC, SSD, SSE) is used for the fluid pressure required by C1 clutch or C3 clutch and appropriately regulated fluid pressure is supplied to the clutch, engaging smoothly without shock.
