Band - Overdrive (O/D)

During 2nd and 5th gear operation, hydraulic pressure is applied to the (O/D) servo.

^ This pressure causes the piston to move and apply force to the band.
^ This action causes the (O/D) band to hold the (O/D) drum.
^ This causes the (O/D) sun gear to be held stationary through the adapter plate and the (O/D) drum.

Band - Low/Reverse

During 2nd gear, 1st gear and REVERSE operation, 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 (O/D) drum.
^ The coast clutch is applied when in manual 1st and 3rd, 4th with (D) cancelled and REVERSE positions.
^ When applied, the coast clutch locks the (O/D) sun gear to the (O/D) planetary carrier, thus preventing the One-Way Clutch (OWC) 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 (OWC) Direct

The direct OWC is a sprag-type OWC that is pressed into the center shaft.

^ The direct OWC is driven by the ring gear of thehe
