AUTOMATIC TRANSAXLE [AW6A-EL, AW6AX-EL]
CENTRIFUGAL HYDRAULIC PRESSURE CANCEL CLUTCH OUTLINE [AW6A-EL, AW6AX-EL]
• When the rotation of the clutch rises, centrifugal force operates on the oil inside the clutch, hydraulic pressure
rises, and the clutch is engaged at an earlier timing. Because of this, a difference arises in rotation between the
input shaft and the output shaft, and shift shock may occur. To solve this, an additional chamber has been
provided opposite the piston hydraulic pressure chamber. This causes centrifugal hydraulic pressure to operate
in the opposite direction with the same force as the piston, counteracting that pressure.
