HIGH CLUTCH
AUTOMATIC TRANSMISSION
3. High Clutch
When the 3rd or 4th gear is selected, hydraulic pressures are applied to the high clutch from the
shift valve and pressure regulator valve. The clutch's drive and driven plates are pressed together,
thus transmitting the engine power from the input shaft to the front planetary carrier through the high
clutch hub.
A cover is placed inside the piston, and the space between the piston and the cover is filled with
ATF. When the high clutch is not in engagement, the centrifugal force generated in the ATF inside
the cover cancels out the centrifugal force generated in the ATF remaining behind the high clutch
piston, thus preventing incomplete disengagement of the clutch.
When the high clutch is engaged, the pressure pushing the clutch piston is much larger than the
counteracting force of the ATF in the cover, so the clutch remains engaged.
