Apply Components
Band-OverdriveDuring 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 position, 1st position 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 position, 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.
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-Intermediate
The Intermediate One-Way Clutch is a spray 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 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.
