The transmission has six hydraulically activated clutches that provide six speeds FORWARD and three speeds REVERSE.
A speed clutch and a direction clutch must be engaged in that sequence in order to send power through the transmission. Table 1 provides the combination of clutches that need to be engaged for each forward and reverse speeds.
| SPEED | ENGAGED CLUTCH |
| Neutral | 4 |
| First Speed Forward | 2 and 6 |
| Second Speed Forward | 3 and 6 |
| Third Speed Forward | 2 and 5 |
| Fourth Speed Forward | 3 and 5 |
| Fifth Speed Forward | 2 and 4 |
| Sixth Speed Forward | 3 and 4 |
| First Speed Reverse | 1 and 6 |
| Second Speed Reverse | 1 and 5 |
| Third Speed Reverse | 1 and 4 |
The No. 1 clutch, No. 2 clutch and No. 3 clutch are closest to the input end of the transmission. These three clutches are the direction clutches. The No. 1 clutch is the reverse direction clutch. The No. 2 clutch is the forward LOW direction clutch and the No. 3 clutch is the forward HI direction clutch. The No. 4 clutch, No. 5 clutch, and No. 6 clutch are the speed clutches.
