Apply Components

Band - Overdrive
During 2nd and 5th gear operation, hydraulic pressure is applied to the overdrive servo.
^ This pressure causes the piston to move and apply force to the band.
^ This action causes the overdrive band to hold the overdrive drum.
^ This causes the overdrive sun gear to be held stationary through the adapter plate and the overdrive drum.

Band - Low/Reverse
During 2nd gear operation, 1st gear operation and REVERSE, hydraulic pressure is applied to the low/reverse servo.
^ This pressure causes the servo to move and apply force to the low/reverse band.
^ This action causes the low/reverse brake drum to be held.
^ This action causes the low/reverse planetary assembly to be held stationary.

Band - Intermediate
During 3rd gear operation, hydraulic pressure is applied to the intermediate servo.
^ This pressure causes the servo to move and apply force to the intermediate band.
^ This action causes the direct clutch drum to be held.
^ The intermediate band holds the intermediate brake and direct clutch drum to the case in 3rd gear.
^ This causes the input shell and forward sun gear to be held stationary.

Clutches - Direct
The direct clutch is a multi-disc clutch made up of steel and friction plates.
^ The direct clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
^ It is housed in the direct clutch drum.
^ During 4th, 5th and REVERSE gear application, the direct clutch is applied transferring torque from the forward clutch cylinder to the direct clutch drum.
^ This action causes the forward sun gear to drive the pinions of the low/reverse planetary carrier.

Clutches - Forward
The forward clutch is a multi-disc clutch made up of steel and friction plates.
^ The forward clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
^ The forward clutch is applied in all forward gears.
^ When applied, the forward clutch provides a direct mechanical coupling between the center shaft and the forward ring gear and hub.

Clutches - Coast
The coast clutch is a multi-disc clutch made up of steel and friction plates.
^ The coast clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
^ The coast clutch is housed in the overdrive drum.
^ The coast clutch is applied when in manual 1st and 3rd, 4th with OD cancelled, and REVERSE positions.
^ When applied, the coast clutch locks the overdrive sun gear to the overdrive planetary carrier, thus preventing the one-way clutch from overrunning when the vehicle is coasting.
^ This allows the use of engine compression to help slow the vehicle and provide engine braking.

One-Way Clutch - Low/Reverse
The low/reverse one-way clutch is a sprag-type one-way clutch.
^ The low/reverse one-way clutch holds the low/reverse drum and low/reverse planetary assembly to the case in 1st and 2nd gear.
^ In all other gears the low/reverse one-way clutch overruns.

One-Way Clutch - Overdrive
The overdrive one-way clutch is a sprag-type one-way clutch that connects the input shaft to the center shaft during drive operation.

The overdrive one-way clutch transmits torque in REVERSE, 1st, 3rd, and 4th gears, as well as in manual 1st, manual 3rd, and manual 4th gears.
^ The input shaft connects through the overdrive planetary carrier to the inner race.
^ The outer race is part of the center shaft.
^ The inner race contacts the assembly of sprags, and wedges them between the inner and outer races.
^ The wedging action causes the input shaft and center shaft to be connected.
