    2003 GM Transmission fluid and filter change. What is this part ? pic attached

    2003 Grand Marque .. While changing transmission fluid and filter I partially drained the pan (fluid dripping down my arms) reached up and pulled the filter off and when I dropped the pan enough to look inside it this part was sitting in the bottom. Does anyone know what it is and where it should go ? Is it important ? Click image for larger version

    Oh man! If that thing fell out the trans will never shift again!!! J\k it is a plug used in the manufacturing process (dip stick insertion?). That just means that the pan has never been dropped before. It is no longer needed.

          same here. Then I found out what it was, and I was even more concerned. The car I was working on had 120k miles and 18 years on original fluid based on the little bobber. Trans worked fine until I caught the car on fire and killed it.

              note that most quick service places that do flushes, don't actually drop the pan... they just cycle the fluid through. Even my volvo dealership does a straight flush, through the trans cooler lines, and never drops the pan.
              So finding that does not mean that the fluid was never changed, per se.
