While working on my sons 2000 v6. (Had the e ginger and trans out of the car) I pulled the trans pan off to change the gasket and filter..... to my surprise there was a little yellow plastic plunger looking thing just laying there in the bottom of the pan. Does anyone know what the heck it is and where it goes? I looked in the fill hole on an 03 auto parts car and saw the same thing floating in the fliud....... I'm so confused
