Clutch: Description and Operation
Clutches - Driving
CLUTCHES - DRIVING
DESCRIPTION
Three hydraulically applied input clutches are used to drive planetary components. The underdrive (2), overdrive (3), and reverse (4) clutches are
considered input/driving clutches and are contained within the input clutch assembly. The input clutch assembly also contains:
^
Input shaft.
^
Input hub.
^
Clutch retainer.
^
Underdrive piston.
^
Overdrive/reverse piston.
^
Overdrive hub.
^
Underdrive hub.
OPERATION
The three input clutches are responsible for driving different components of the planetary geartrain.
NOTE: Refer to ELECTRICAL DIAGNOSTICS [42RLE]/DIAGNOSIS AND TESTING for a collective view of which clutch elements are applied
at each position of the selector lever.
UNDERDRIVE CLUTCH
The underdrive clutch is hydraulically applied in first, second, and third (direct) gears by pressurized fluid against the underdrive piston. When the
underdrive clutch is applied, the underdrive hub drives the rear sun gear.
OVERDRIVE CLUTCH
The overdrive clutch is hydraulically applied in third (direct) and overdrive gears by pressurized fluid against the overdrive/reverse piston. When the
overdrive clutch is applied, the overdrive hub drives the front planet carrier.
REVERSE CLUTCH
The reverse clutch is hydraulically applied in reverse gear only by pressurized fluid against the overdrive/reverse piston. When the reverse clutch is
applied, the front sun gear assembly is driven.
