Second test drive ...tuner detatched/running stock settings....temp steady at 175 to 185...stopped checked cooling lines...bottom line hot top line warm...trans hot like bottom line. I wonder if my troubles are over. I'll know tomorrow on long trip. Is it possible that the upper tube lower temp is actually cooled oil returning to the trans? Is it possible my DSG tuner caused the problem? I know it has an anti-slip feature to it.
