OVERDRIVE ONE-WAY CLUTCH
The overdrive one-way clutch prevents the overdrive sun gear and planetary carrier from rotating counter-clockwise.
The outer race is the overdrive carrier; the inner race is the overdrive sun gear.
When the overdrive sun gear is driven by the applied overdrive clutch, the sprags connect the overdrive sun gear and overdrive carrier. This supplies
direct drive from the turbine to the forward clutch input shaft.
In overdrive, the overdrive clutch is released and the overdrive brake is applied. This holds the overdrive clutch housing and the overdrive sun gear.
The driving force of the engine is then transferred through the carrier (which rotates around the sun gear). The clockwise rotation of the carrier
overruns the sprag. This allows free movement of the carrier, permitting overdrive.
ONE-WAY CLUTCH NO. 1
One-way clutch No. 1 prevents the sun gear from rotating counter-clockwise. This occurs only when the second brake is applied in 2nd, 3rd and
overdrive.
The outer race of one-way clutch No. 1 is actually the second brake hub; the inner race is the sun gear.
When the second brake is not applied, the sun gear rotates counter-clockwise as in 1st and reverse. The sprags are overrun.
However, when the second brake is applied, the outer race (second brake hub) is held. The sun gear attempts to continue turning counter-clockwise as
in 1st gear, but the sprags bind the second brake and the sun gear, preventing counter-clockwise rotation.
ONE-WAY CLUTCH NO. 2
One-way clutch No. 2 prevents the front planetary carrier from turning counter-clockwise. It is used in 1st gear, primarily for breakaway.
The outer race is the front planetary carrier; the inner race is the Low and Reverse Brake reaction plate.
When the vehicle starts to move, the forward clutch drives the rear planetary ring gear. This makes the sun gear rotate counter-clockwise. The front
planetary carrier then attempts to turn counter-clockwise also. The sprags bind and prevent this. Therefore, the driving force is transferred to the
output shaft via the front planetary ring gear.
