Abstract:
A transmission controller permits a 2-1 shift, in which a gear position of a subtransmission mechanism is changed from a second speed to a first speed, when an accelerator pedal has been depressed to or above a predetermined opening. The gear position of the subtransmission mechanism is changed from the second speed to the first speed when an actual through speed ratio passes a mode switch line from a High side to a Low side while the 2-1 shift is permitted in the subtransmission mechanism.
