^ Temporarily insert the overdrive planetary gear carrier assembly into the one-way clutch rollers for verification of the one-way clutch.
^ The planetary gear must rotate counterclockwise and hold when rotated clockwise.
^ Remove the planetary gear carrier assembly.
^ Inspect for cracks in the roller cage and wear on the roller clutch, and the press fit of the one-way clutch to the center shaft.

NOTE: Inspect the overdrive planetary.
^ Inspect the pinion gears for damaged or excessively worn teeth, and for free rotation.
^ Check the pins and shafts in the planetary assemblies for loose fit and/or complete disengagement.
^ Inspect the overdrive one-way clutch inner race, and the inner and outer races for scored or damaged surface areas where the rollers contact the races.
^ Inspect the sun gear for damaged or worn teeth.
^ Inspect the No. 2 bearing for damage.
