Does anybody have any idea what this is and why it was floating in the transmission pan? The vehicle is a 2004 F150. Was changing fluid on it and went to pour the fluid out of the pan and this was rolling around in there. I have no idea how long it has been in there. The last trans fluid change was 60k ago and was done before I worked here, it was taken somewhere for that service. I guess it could have fallen since then, or if they just sucked the fluid out and didn't remove the pan, it could have been in there from the factory. I could not find any place that seemed like it would go into. The truck ran fine and had no transmission issues with this in the pan.
