Abstract
In a transmission control device, a controller determines failure of a rotation sensor. A hydraulic control circuit and the controller variably control a speed ratio of a variator, and in a case where the failure is determined, execute first control of restricting a shift range of the variator. The hydraulic control circuit and the controller variably control a gear position of a sub-transmission mechanism, and in a case where the failure is determined, execute second control of fixing the gear position of the sub-transmission mechanism to first speed. The hydraulic control circuit and the controller execute the second control at a different timing from the first control in a case where the gear position of the sub-transmission mechanism upon a determination of the failure is second speed.
