Band - Overdrive (O/D)
For component location, refer to Transmission Transmission Assembly in the Assembly.
During 2nd and 5th gear operation, hydraulic pressure is applied to the Overdrive (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
For component location, refer to Transmission Transmission Assembly in the Assembly.
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
For component location, refer to Transmission Transmission Assembly in the Assembly.
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
For component location, refer to Transmission Transmission Assembly in the Assembly.
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
For component location, refer to Transmission Transmission Assembly in the Assembly.
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
For component location, refer to Transmission Transmission Assembly in the Assembly.
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 O/D drum.
- The coast clutch is applied when in manual 1st and 3rd, 4th with O/D canceled, and REVERSE positions.
- When applied, the coast clutch locks the O/D 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 (OWC) - Low/Reverse
For component location, refer to Transmission Transmission Assembly.
The low/reverse One-Way Clutch (OWC) is a sprag-type OWC.
- The low/reverse OWC 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 OWC overruns.
OWC - O/D
For component location, refer to Transmission Disassembly.
The O/D OWC is a sprag-type OWC that connects the input shaft to the center shaft during drive operation.
The O/D OWC 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 O/D 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.
