構造。 When the engine is running at high speed, the oil from the oil pump bypasses the torque converter and oil cooler and is directly connected to the lubrication path that leads the oil discharged from the oil pump of the automatic transmission to the lubrication section via the torque converter and oil cooler. a first position that provides a bypass passage for supplying the lubricating oil and closes the bypass passage to communicate a lubricating oil passage from the oil cooler with a passage leading to the lubricating section;
An automatic transmission characterized in that a switching means is provided that controls switching between a second position in which the bypass passage communicates with the passage portion and a lubricating oil passage from the oil cooler directly communicates with the inside of the oil pan. Lubricated structure.
