Abstract
Provided is an automatic transmission capable of smoothly switching a switching mechanism. A control part ECU of a transmission recognizes an input torque and a friction torque when an instruction to switch a two-way clutch from a fixed state to a reverse rotation prevention state is received while a first clutch, a second clutch and a third clutch are in an open state, and switches the two-way clutch from the fixed state to the reverse rotation prevention state when the input torque is equal to or greater than the friction torque.
