| 13 | Power input from torque converter |
| 14 | Power output to output shaft |
Engine torque is transferred, via operation of single or combinations of clutches to the four planetary gear trains. All gear trains are controlled by reactionary inputs from brake clutches to produce the eight forward gears and the reverse gear.
The ratios are as follows:
| GEAR | 1ST | 2ND | 3RD | 4TH | 5TH | 6TH | 7TH | 8TH | REVERSE |
|---|---|---|---|---|---|---|---|---|---|
| Ratio | 4.714 | 3.143 | 2.106 | 1.667 | 1.285 | 1.000 | 0.839 | 0.667 | -3.295 |
