Finally got the 550 to a friends heated barn and drained the fluid out of the tranny the picture shows what fell out of the back baffle. Any thoughts on what it is? I am pulling the top off Maybe as early as Monday but would like to know what you think it is. Looks like a pin and bearing assembly to me. But I am pretty ignorant to what I am going to find when I open it up. 

Thanks for any help or thoughts before the cap comes off.
