Abstract
An automatic transmission includes an oil temperature detecting unit configured to detect an oil temperature of the hydraulic oil, and a controller configured to perform the control of the speed ratio on a basis of the oil temperature obtained from the oil temperature detecting unit. The controller is configured such that if the controller has failed to obtain the oil temperature from the oil temperature detecting unit, the controller outputs a command to restrict an output from the driving force source, and such that if the controller has obtained the oil temperature from the oil temperature detecting unit again, the controller gradually cancels the command to restrict the output from the driving force source.
