Zusammenfassung:	To provide a control device of a transmission which can effectively shorten a lag at changeover when setting a traveling mode (or a gear change stage) by switching an engagement state and a release state of an engagement mechanism.SOLUTION: An engagement force of a first engagement mechanism is lowered when switching a traveling mode to a second traveling mode from a first traveling mode, release thrust for releasing the first engagement mechanism is generated when the engagement force is lowered to a threshold or lower, and the release thrust is imparted by prescribed release thrust before a start of the release of the first engagement mechanism (step S5), and gradually increased up until the release of the first engagement mechanism is finished (step S8).SELECTED DRAWING: Figure 14 【課題】係合機構の係合状態と解放状態とを切り替えて走行モード（あるいは変速段）を設定する際に、その切り替えにおけるラグを効果的に短縮することが可能な変速機の制御装置を提供する。【解決手段】第１走行モードから第２走行モードに切り替える際に、第１係合機構の係合力を低下させ、かつ前記係合力が閾値以下に低下した際に第１係合機構を解放させる解放推力を発生させ、その解放推力は、第１係合機構の解放開始前に所定の解放推力で付与され（ステップＳ５）、かつ第１係合機構の解放完了まで漸次的に増大されるように構成されている（ステップＳ８）。【選択図】図１４
