2011 Cruze LT(1.4L, 6t40 trans)
At about 50k miles I did a transmission fluid change. That's about the same time I got the car. Upon draining the fluid I found that the fluid was black as oil with a reddish tint in the light. The fluid did not smell burnt. Smelt like regular old ATF. I ran my magnet through the drain pan in search of shavings. Nothing stuck so I didn't think too much of it and filled the car back up and went through the procedure to do so. When I pulled the check plug I noticed the fluid was still black so I knew I had better get a flush. After talking to the dealership they told me it wasn't covered under warranty and that if have to pay $200 to get it done. Naturally I did it myself and saved $100. I started by draining and refilling into an oil pan. Then I flushed the transmission through the cooler line and let it stream out until it turned into a bright red color in a separate pan. Ran my magnet through both pans and nothing stuck so I thought I was good. Let the car get up to temp and drained out any excess fluid. After buttoning her up and cleaning up my mess I drained the fluids and upon inspection of the drain pan I had used to initially drain it (not the flushing container) I saw some metal shavings. They were small and fine but there was a decent amount of shavings. It also looked like there might have been some small rocks in the pan. That's the first time I've ever seen rocks in a pan. What I'm wondering is if the metal didn't stick to the magnet what component could it be and should I be worried about a transmission rebuild in the next 15k miles? The metal was silver in color. What could appear like small rocks from inside the transmission? Thanks for your input on this topic.
