so, dct oil heats up itself, without any influence of exchanger.

i already made some screen shots about dct from rheingold, but it's on my notebook in garage.
Thanks for the info. I had know idea the there is a thermostat. i completely agree, if the thermostat is on the line going to the heat exchanger, then yeah, the dct must be heating up the oil on its own.
