Forward One-Way Clutch (OWC)
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The forward one-way clutch (OWC) is either a sprag or mechanical diode type, one-way clutch. The forward OWC combines with the forward clutch to connect the turbine shaft assembly to the low/intermediate sun gear assembly in 1st, 2nd and 3rd gears. The forward OWC overruns during all coasting operations and is always overrunning in 4th gear.
