Abstract
A control apparatus for a vehicle transmission that includes: transmission gears disposed on a shaft; a switching mechanism which is to be switched between a connecting state in which one of the transmission gears is rotatable integrally with the shaft and a disconnecting state in which the one of the transmission gears is rotatable relative to the shaft; a shift fork for axially moving the switching mechanism; and a shift barrel to be rotated to position the shift fork. The switching mechanism includes first and second rings and an elastic member which is disposed between the first and second rings in the axial direction and connects the first and second rings. The control apparatus determines that a failure occurs in the vehicle transmission, when a value related to a reaction force that acts on the shift barrel during rotation of the shift barrel is deviated from a predetermined range.
