Abstract
An automatic transmission including an electric actuator, a shift operating unit, rotation position detecting means, a locating unit for locating a manual shaft, and a controlling unit for driving and controlling the actuator is constructed of an electric current detecting unit for detecting a driving current of the actuator, a shifting position calculating unit for calculating a shifting position of the manual shaft on the basis of detection by the electric current detecting unit of a change in the driving current of the actuator at the time when a detent pin gets over a convex to be fitted in a predetermined concave in shifting, and a rotation position detection learning unit for learning a relation between the shifting position calculated by the shifting position calculating unit and an output value of the rotation position detecting unit.
