御装置。 The first shift valve includes a first multi-disc clutch connected by a first oil passage, and the second shift valve includes a second multi-disc clutch connected by a second oil passage, and the shift valve operates to change the speed. In an automatic transmission in which one multi-disc clutch is sometimes released and the other multi-disc clutch is engaged, the oil in the multi-disc clutch on the side that is released among the first and second multi-disc clutches is 1. A clutch hydraulic control device for an automatic transmission, characterized in that a clutch hydraulic control device for an automatic transmission is provided with a low engagement pressure residual means for causing a low engagement pressure to remain for a predetermined period of time during gear shifting.
