A torque converter consists of the hydrodynamic clutch device and the lock-up clutch device. The lock-up clutch connects directly between an engine and an automatic transmission for the high efficiency and the low fuel consumption. Recently, lock-up clutch is changed slip control instead of on-off control. The slip control of lock-up clutch is necessary for the better fuel economy. But slip control of lock-up clutch system has high thermal resistance and durability problem. The lock-up capacity and cooling flux are very important for solution of high temperature and durability. This test evaluates noise characteristics by the cooling hole of the slip controlled torque converter.
