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.
