Clutch: Description and Operation

CLUTCH-FORWARD
The forward clutch couples the input shaft to the forward sun gear in first, second and third gears.





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. It is applied in reverse range only.





CLUTCH-INTERMEDIATE
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-INTERMEDIATE ONE-WAY
The intermediate one-way clutch is a roller clutch that works with the intermediate friction clutch to hold the reverse sun gear stationary in second gear during acceleration. This one-way clutch freewheels in third gear and during coasting in second gear, OD and D ranges.





CLUTCH-PLANETARY (LOW) ONE-WAY
The planetary (low) one-way clutch is a roller clutch that holds the pinion carrier stationary in first gear, (OD and D ranges). During automatic coasting downshifts into first gear (OD and D ranges), it freewheels so that there is no engine braking.
