Mystery part for DeWalt DC970 reassembly

Hey

So I opened up the case on my DeWalt DC970 18V drill and of course, wasn't careful enough and stuff spilled out when I separated the two halves. I caught the motor assembly in time, but I could hear at least a couple parts hit the ground, never to be found again. One of these days I'll retain what I learn....

Anyways, I'm trying to reassemble and I'm stuck on a mystery part

Based on the next image, I'm thinking it's a part of the speed shifter. You can see the bend of something metal holding up the shifter with the motor out that looks very close to the mystery part. Unfortunately though, any image I can find of the shifter online is a picture of just the top of the shifter, nothing of the bottom. Every parts diagram I can find does the same thing; it's sold as a single part.

In the image above, it looks like the part attaches to the motor assembly farther down than the shifter does. But I can't find anywhere for it to attach to anything.

The hole in the center of the part does fit snuggly into the shifter bottom, but of course I don't know which direction it's supposed to go.

Am I missing another part that helps this attach to the motor?

Is this mystery part just a random doohickey I found on my floor and has nothing to do with the drill?

Answers and advice greatly appreciated.
