One-Way Clutch - Planetary (Low)

WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For component location, refer to Transmission .

The planetary (low) OWC is a roller clutch that holds the planetary gearset in 1st gear, Overdrive (Circle D) and D ranges. During automatic coasting downshifts into 1st gear (Overdrive (Circle D) and D ranges), the planetary OWC freewheels so there is no engine braking.
