Abstract
An assembly for an automatic transmission includes a casing, a carrier of a planetary gear set, a hydraulically actuated brake that driveably connects the carrier and the casing mutually when the brake is engaged in reverse drive and disconnects the carrier from the casing when the brake is disengaged in forward drive, and an overrunning clutch including an outer race driveably connected to the casing, an inner race driveably connected to the carrier, and multiple rockers carried on the inner race that pivot toward engagement with the cam surfaces, contact of the clutch with the casing providing a reaction to a force tending to engage the brake.

An assembly for an automatic transmission comprising:
- a casing;
- a carrier of a planetary gearset;
- a friction brake for opening and closing a connection between the carrier and the casing;
- an overrunning brake including an outer race connected to the casing, an inner race, rockers on the inner race that engage and disengage the outer race, a spline engaged by the friction brake, and a second spline engaged by the carrier.
An assembly for an automatic transmission comprising:
- a casing;
- a carrier of a planetary gearset;
- a friction brake for opening and closing a connection between the carrier and the casing, including alternating discs and plates;
- an overrunning brake including an outer race connected to the casing, an inner race, rockers on the inner race that engage and disengage the outer race, a spline engaged by the discs, and a second spline engaged by the carrier.
