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 1st, 3rd, drive 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-Direct
The direct one-way clutch is a spray-type one-way clutch that is pressed into the center shaft.
The direct one-way clutch is driven by the ring gear of the overdrive planetary carrier.
The direct one-way clutch holds and drives the outer splines of the center shaft in 1st, 3rd, 4th and reverse gears.
The direct one-way clutch overruns during all coast operations and at all times in 2nd and 5th gear.
One-Way Clutch-Low/Reverse
The low/reverse one-way clutch is a spray-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.
