To keep the new 8 gear box within the same overall size as their previous 6 gear model AW have incorporated two smaller lock-up clutches to replace a single, larger one. I am not an expert but that is what I read. Thus the description as a double clutch transmission does not mean it has lost the basic torque convertor configuration.

Yes you are correct , Volvo have been using the torque converter Lock up clutch since 1982 cant think of any earlier boxes with it though .
