WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The low/reverse (1, R) clutch holds the rear planetary carrier stationary to the transmission case. The low/reverse (1, R) clutch is applied in PARK, REVERSE, NEUTRAL, manual 1st gear and DRIVE 1st gear, below 8 kph (5 mph). The low OWC is a brake clutch that also holds the rear planetary carrier in one direction and allows it to freewheel in the opposite direction eliminating engine braking in 1st gear when the transmission is in drive. The low OWC is also a pressure plate for the low/reverse (1, R) clutch.
