ABSTRACT:
A planetary overdrive gear mechanism for an automatic transmission utilizing a double-acting one-way clutch with means to immobilize the cage for the one-way clutch with the rollers in an intermediate position whereby the inner and outer races are free to rotate relative to one another and a brake mechanism for the inner race of the clutch which is integral with the sun gear whereby with the brake applied and the one-way clutch neutralized, an overdrive ratio is established through the mechanism, and with the brake released and the cage control released, a two-way direct drive is established through the mechanism.
