A differential having an overrunning clutch provided. The differential includes an inertial compensation assembly that is configured to counteract movement of a roller cage relative to a clutch cam housing to prevent unintended roller cage and clutch cam housing engagements. Unintended roller cage and clutch cam housing engagements may occur when the differential is subject to rotational accelerations caused, for example by, vehicle acceleration/deceleration, sudden braking, sudden changes in traction, road irregularities, bumps, jumps, u-joint phasing, etc.

An overrunning clutch (ORC) differential is provided that includes a locking mechanism that is configured to lock rotation of a clutch cam housing to a roller cage to retain a centering of each roller in an associated cam roller feature to prevent torque from being communicated between the clutch cam housing and first and second hubs when the locking mechanism is activated.

Provided is an automatic transmission with which a large impact is hardly applied to the component of the switching mechanism or the switching control circuit when the drive source is re-driven. When a drive source ENG is determined to be in the stopped state, if the position of a slider HC1 does not correspond to the position the control part

ECU instructed before the drive source ENG is determined to be in the stopped state, the control part ECU of the automatic transmission TM transmits a signal for switching a two-way clutch TW to a state corresponding to the state of a slider HC1.
