1st Gear

GFD625854Courtesy of FORD MOTOR COMPANY
Item  Description 
1 E clutch
2 Input shaft
3 Shell and sun gear No. 4
4 A clutch
5 One-Way Clutch (OWC)
6 Ring gear No. 4
7 Output shaft and planetary carrier No. 4
8 D clutch

The E clutch is applied allowing torque to be transferred from the input shaft to the shell and sun gear No. 4. The A clutch and the One-Way Clutch (OWC) are both applied to hold the ring gear No. 4 stationary on acceleration. The shell and sun gear No. 4 drives the pinions of the output shaft and planetary carrier No. 4 in a 4.69 reduction gear ratio. The D clutch is applied to reduce frictional losses from a released clutch, but does not contribute to powerflow.
