APPLY COMPONENTS
There are eight apply components used to drive or hold the planetary gearset components.
Scheme 157
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.
Scheme 158
The low and reverse band holds the pinion carrier in reverse. The reverse band also applies in manual 1 position to provide engine braking.
Scheme 159
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.
Scheme 160
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.
Scheme 161
The direct clutch couples the input shaft to the planet carrier through the stub shaft in third and fourth gears.
Scheme 162
The reverse clutch couples the input shaft to the reverse sun gear, applied in reverse range only.
Scheme 163
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.
Scheme 164
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.
Scheme 165
Scheme 166
The transmission uses a gerotor-type design front pump support and gear. The pump provides the volume of fluid needed to charge the torque converter, main control assembly, cooling system and lube system. Pump pressure is regulated by the main regulator valve. The pump has an internal boost circuit which is more efficient at lower engine speeds.
