Low One-Way Clutch
WARNING: This page is about a different car, the 2002 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
The low one-way clutch is engaged in first gear, with the exception of manual low. In manual low, the low one-way clutch is locked out by the application of the low/reverse clutch. The low one-way clutch prevents the front planet from rotating counter-clockwise. The low one-way clutch overruns during deceleration in first gear, with the exception of manual low.
