Compare of used V new DCT Filter

C8 DCT filter with 20,000 miles over what new one looks like

That looks pretty yucky, but then 20k Miles is a lot of miles. Perhaps a shorter mileage between changes is needed.?

Really 7,500 miles less than as GM requires the DCT filter changed by 7,500 miles, that first change is free and done by GM
C8 had 20,000 miles when this second one was taken out

Most of the crap comes from the dual clutches shedding
