I just changed my 6 speed oil at 10,000 miles. There was the silver/grey sheen of metal particles in the oil. This is normal for break-in of a new transmission. It IS NOT something you should leave in for the life of the transmission unless you want that life to be shorter than it should be. Don't believe the dealier/factory steer manure advice that the oil in the 6 speed is "lifetime"
