Item  Description 
1 C clutch
2 D clutch
3 E clutch
4 Planetary gearset No. 2
5 Planetary gearset No. 3
6 Sun gear No. 1

11 Ring gear No. 4
12 Output shaft and planetary carrier No. 4

The C clutch, D clutch, and the E clutch are applied to provide multiple inputs at the same speed to the 2nd and 3rd planetary gearsets. These inputs effectively lock the 2nd and 3rd planetary gearsets and cause sun gear No. 1 and the shell and sun gear No. 4 to rotate at a 1:1 ratio with the input shaft. The A clutch is holding the ring gear No. 1 stationary causing the planetary carrier No. 1 and the ring gear No. 4 to rotate at a 3.11 reduction ratio. The 2 inputs to the 4th planetary gearset cause the output shaft and planetary carrier No. 4 to rotate at a 2.15 ratio.
