1. A transmission controller configured to control a transmission, the transmission being configured to transmit power between a primary shaft and a secondary shaft while changing a gear ratio between the primary shaft and the secondary shaft, the transmission controller comprising:
at least one processor; and
at least one memory coupled to the at least one processor,
the at least one processor being configured to perform processing including:
performing first control for upshifting the transmission when a target rotational speed of the primary shaft reaches or exceeds a first threshold; and
performing second control for upshifting the transmission when an engine speed reaches or exceeds a second threshold,
wherein the second control is executed when the target rotational speed is higher than or equal to a set value set for each gear of the transmission, and is not executed when the target rotational speed is lower than the set value.
