When I got the current V70 D5 AWD (2005) I contacted Volvo with caravan MPLM or whatever it's called and scope of operation, i.e. Europe, all seasons, and I have an e-mail from them saying no additional cooler was needed for the auto box.
Maybe with lock-up on auto-boxes now they do not get so hot as they did when torque convertor was always in slip?
