BAND - INTERMEDIATE
The intermediate band locks the rear sun gear and drum to the transmission case. The intermediate band encircles the rear sun gear and drum and operates during different conditions depending on the engine application. One end of the intermediate band is secured to the servo band lever, the other end to the intermediate band servo retainer.

BAND - INTERMEDIATE, SERVO
When hydraulic pressure is applied between the intermediate band servo retainer and the servo band piston, the servo band piston overcomes the spring force and causes the intermediate band to lock the rear sun gear and drum.

When hydraulic pressure is applied between the servo band and the transmission case, the servo band piston is pressed toward the servo retainer side. This allows the intermediate band to expand by its own spring force and release the rear sun gear and drum.

When hydraulic pressure is applied simultaneously between the servo band piston and intermediate band piston retainer and the servo band piston and the transmission case, the servo band piston is pressed toward the servo retainer side due to the difference in surface area. The rear sun gear and drum is released and rotates freely.





CLUTCHES - FORWARD
When hydraulic pressure acts upon the forward clutch piston, the forward clutch disc pack is pressed tightly together, and the rotation of the turbine shaft is transmitted through the reverse clutch drum and one-way clutch to the primary sun gear.

CLUTCHES - COAST
When hydraulic pressure acts on the coasting clutch piston, the coasting clutch disc pack is pressed tightly together, and the rotation of the turbine shaft is transmitted through the reverse clutch drum, the coasting clutch drum, and one-way clutch inner race, to the primary sun gear. With the coasting clutch engaged, the forward clutch is engaged, resulting in the one-way clutch becoming locked. Without the coasting clutch engaged, the one-way clutch will overrun during deceleration.

The return spring is common for the forward clutch and the coasting clutch.

CLUTCHES - DIRECT
When hydraulic pressure acts on the direct clutch piston, the direct clutch disc pack is pressed tightly together, and the rotation of the turbine shaft is transmitted through the direct clutch cylinder and carrier hub to the front planet. The direct clutch operates during third and fourth gear operation.

CLUTCHES - REVERSE
When hydraulic pressure acts on the reverse clutch piston, the reverse clutch disc pack is pressed tightly together, and the rotation of the turbine shaft is transmitted through the reverse clutch drum to the rear sun gear and drum. The reverse clutch operates during reverse movement of the vehicle.





BAND - INTERMEDIATE, SERVO
When hydraulic pressure is applied between the servo retainer and the servo piston (intermediate band engagement side), the servo piston overcomes the spring force and acts on the intermediate band, locking the rear sun gear and drum. When hydraulic pressure is applied between the servo piston and transmission case (intermediate band disengagement side), the servo piston is pressed toward the servo retainer side. The intermediate band expands by its own spring force, releasing the rear sun gear and drum.

When hydraulic pressure is applied simultaneously between the servo retainer and the servo piston and between the servo piston and transmission case, the servo piston is pressed to the servo retainer side as a result of the difference of the surface area between the two, releasing the rear sun gear and drum. The intermediate band operates during second gear and fourth gear.

CLUTCHES - LOW/REVERSE
When hydraulic pressure acts on the low/reverse clutch piston, the low/reverse clutches are pressed tightly together, and the transmission case and the low/reverse clutch inner race are connected. The rotation of the front planet stops when the low/reverse clutch is applied. This brake operates during manual low (first gear) and reverse.








ONE-WAY CLUTCHES
The forward one-way clutch on the front planet is a roller-type clutch. The one-way clutch allows rotation in one direction only. If the clutch tries to rotate in the opposite direction, the rollers are forced into the smaller slots of the gauge and the outer race is secured to the inner race. The low one-way clutch on the primary sun gear is a sprag-type clutch. If the clutch tries to rotate in the opposite direction, the sprags become wedged between the inner and outer races and rotation is stopped.
