I went and got oil changed at valvoline and they pulled the trans dipstick and there was something on it. first thought was metal shavings so I brought it up to the dealer and they checked it. I had 100 miles before warrenty goes away. They checked it and said it is dirt. That it needs to be flushed and both filters changed. It has a grey look to it. I now have no warrenty and Im getting it flushed. What can I do if it is metal shavings???
