I recently did a transfer case flush on my new to me 1997 GMC Sierra with 75,000 miles on it. Today I rechecked the fliud to make sure it was still 100% full and it was. When I opened the fill hole a little leaked out and I dabbed it up with my finger and I could see little tiny metal flakes in it. The fluid was nice and red though. Is this normal or do I have a problem? I never noticed this before on my other trucks. All seem well with the truck.
Also I flushed the front and rear diff's and the rear looks clean but the front still looks a little dirty but much better then before. Should I flush it again or is it ok? Thanks!!!
