hi, i took the pan off of my 4r70w and this part was sitting in the pan. does anybody know what it is and where it goes? thanks
A plug used in the assembly of the trans at the factory. Simply gets pushed in the pan when the dipstick get installed. Nothing important at all.
It's the all-important "discombobulator" put it back into the pan immediately. It'll never shift right without it. :Handshake
