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, D4, 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.

Clutches-Intermediate
The intermediate clutch is a multi-disc stationary clutch made up of steel and friction plates, which are in a module assembly that includes the cylinder and frictions.
^ Applied with hydraulic pressure.
^ Disengaged by a return spring and releasing of hydraulic pressure.
^ Hydraulic pressure is feed through a feed tube in the case worm trail.
^ Uses a bonded piston in an aluminum housing.
^ Applied in during a 2-3 shift event.
^ Transfers torque from the sun gear to the planetary carrier.
^ Torque transfer causes the one way clutch to engage and holds the sun gear from turning, delivering 3rd gear.

One-Way Clutch-Direct
The direct one-way clutch is a sprag-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-Intermediate
The Intermediate One-Way Clutch is a sprag type one-way clutch.
^ The Intermediate One-Way Clutch connects the intermediate assembly to the input shell and sun gear assembly in third gear.

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.
