Abstract

　低油温時の車両停車時に気泡がトルクコンバータ内に滞留、蓄積し、発進時に十分な伝達トルクが得られずに車両の駆動性能が損なわれることを改善する。 　エンジン３０の始動初期等の低油温時においてＤレンジ等の駆動レンジでの車両停車時に、エア混じりの作動油が第２油路１３２からトルクコンバータ３２内に供給されることがある。この場合、第２油路１３２からロックアップクラッチ２８に第２ライン油圧ＰＬ２が供給されるロックアップクラッチ解放時には、第３油路１３４が遮断（閉塞）されて作動油の排出が禁止される。そのため、低粘性による大きな管路抵抗に拘らずトルクコンバータ３２内の作動油が確実に第１油路１３０からクーラー油路１４０を通ってオイルクーラー１４２へ排出される。こうして、作動油の排出に伴ってトルクコンバータ３２内の気泡が低減される。
