ABSTRACT:
A multiple-ratio automatic transmission having plural torque delivery paths that are established and disestablished by a roller clutch and brake system. The clutch and brake system establishes and disestablishes torque flow paths while preventing simultaneous clutch or brake engagement. The clutch and brake system is capable of accommodating instantaneous torque reversals during ratio changes. Simplified clutch and brake system actuators trigger the application and release of the clutches and brakes during ratio changes.
