Caravan AWD V6-201 3.3L (1991)
Clutch: Description and Operation
Overdrive and Reverse Clutch
The Overdrive/Reverse (OD/REV) piston is between the input hub and the clutch retainer. This piston is unique in design for the following reasons:
-
It operates two separate clutches
-
It is located on the outside of the clutch retainer that houses the two clutches it operates
The overdrive clutch is splined to the overdrive hub assembly, and the overdrive hub is splined to the front carrier assembly. When the overdrive clutch
is applied hydraulically, the front carrier assembly is an input to the planetary gear-set in third (direct) and fourth (overdrive) gear ranges. The reverse
clutch is splined to the front sun gear assembly. When the reverse clutch is applied hydraulically, it drives the front sun gear which is the input to the
planetary gear-set in reverse gear range.
