One-Way Clutch Operation

ONE-WAY CLUTCH OPERATION

One-Way Clutch No.1
^ The one-way clutch outer race (front internal gear) rotates clockwise (seen from the torque converter side) freely, but the sprags rise to lock the rotation when the outer race tries to rotate counterclockwise.
^ The one-way clutch No.1 locks the counterclockwise rotation of the front internal gear, and also locks the counterclockwise revolution of the rear planetary gear via the rear planetary carrier.

Note: All direction of rotation are viewed from the torque converter.





One-Way Clutch No.2
^ The one-way clutch outer race (direct clutch) rotates counterclockwise (view from torque converter) freely, however, the roller moves to the right (view from torque converter) and locks the rotation when it tries to rotate clockwise.
^ One-way clutch No.2 locks the clockwise rotation of the direct clutch, and also locks the clockwise rotation of the secondary sun gear via the direct clutch.
