Internal diagram for transmission on 98 ford expedition

We need to find out where a part came from that fell out when my husband was changing the transmission fluid. It looks like a plug of some sort. It is beige in color with a black rubber band around it and a stick sticking out of it that is about an inch or so long. If you know where we can find a diagram of the internal part of the transmission then maybe he can figure out where the part goes.

The original problem was going into passing gear it would just lose power and you would have to let it shift back down then try and give it gas again.

    Thank you so much!!! That is the part. Although I have to admit that I am a little mad that the transmission fluid may have never have been changed in this. I just bought it in March last year.

    We will check in to the electronic module if after the work we do to it right now doesn't fix the problem. It is actually something we were thinking it might be.

    Thank you again so much!!! Now he can rest tonight and not worry. lol.....

Actually its a plug that's placed in the dipstick hole during manufacture. when they insert the dipstick tube the plug just stays harmlessly in the pan until the first fluid change. It's nothing you need.

If you are still having performance issues, it may be electrically related as this transmission is controlled by the electronic module.
