Overdrive Clutch
The overdrive clutch is a drive clutch that transfers power from the direct/overdrive hub and shaft assembly to the rear planetary carrier. The overdrive clutch is applied in 4th, 5th and 6th gear.
Hydraulic pressure from the regulator valve in the valve body pushes the overdrive clutch piston against the overdrive clutch pack to apply the clutch. The input shaft transfers torque to the rear planetary sun gear as a result of the clutch being applied.
