Main Components and Functions
Apply ComponentsThere are eight apply components used to drive or hold the planetary gearset components.
Band-Overdrive
The overdrive band holds the reverse clutch drum stationary in fourth gear and manual 2. This action causes the reverse sun gear to be held in these ranges.
Band-Low and Reverse
The low and reverse band holds the pinion carrier in reverse. The reverse band also applies in manual 1 position to provide engine braking.
Clutch-intermediate
Intermediate Clutch Disassembled View
The intermediate clutch works with the intermediate one-way clutch to hold the reverse sun gear stationary in second gear. The intermediate clutch remains applied in third and fourth gears, but does not transmit power,
Clutch-Forward
The forward clutch couples the forward clutch cylinder and input shaft to the forward sun gear in first, second, and third gears. The forward clutch is not applied in fourth gear.
Clutch-Direct
The direct clutch couples the input shaft to the planet carrier through the stub shaft in third and fourth gears.
Clutch-Reverse
The reverse clutch couples the input shaft to the reverse sun gear, applied in reverse range only.
One-Way Clutch-Planetary (Low)
The planetary (low) one-way clutch is a roller clutch that holds the planetary gearset in first gear (D) and D ranges. During automatic coasting downshifts into first gear (D) and D ranges), the planetary one-way clutch freewheels so there is no engine braking.
One-Way Clutch-4ntermediate
The intermediate one-way clutch works with the intermediate friction clutch to hold the reverse clutch drum and reverse sun gear stationary in second gear during acceleration. The intermediate one-way clutch freewheels in third gear and during coasting in second gear, (D) and D ranges.
