the torque converter and oil cooler (65) into the transmission (converter lockup clutch depressurized). In its
regulating position (slipping, torque converter lockup clutch pressurized), a reduced volume of lubricating oil
(p-Sm) flows through the annular passage (27a) bypassing the torque converter and passing direct through the
oil cooler (65) into the transmission. The other part of the lubricating oil (p-Sm) is led via the restrictor (a) into
the torque converter for cooling the converter lockup clutch (KUB).
