So I had my EGT serviced at the dealer recently, and they informed me one thing that's recommended for the Dual-Clutch is to have the transmission fluid changed out after 60k-ish miles. Is this really needed? I don't race or track the car (though I would love to some day), but it is my daily and I do drive over 400 miles a week for work, mostly on backroads. What do you guys recommend?
