Overdrive (O/D) (4, 5, 6) Clutch
WARNING: This page is about a different car, the 2010 Mercury Milan and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The O/D clutch is a drive clutch that transfers power from the direct/O/D clutch hub assembly to the rear planetary carrier. The O/D clutch is applied in 4th, 5th and 6th gears.
Hydraulic pressure from the regulator valve in the valve body pushes the O/D clutch piston against the O/D clutch pack to apply the clutch. The input shaft and direct/O/D clutch hub assembly transfers torque to the rear planetary carrier as a result of the clutch being applied.
