2010 tundra 4x4 actuator

I was having trouble with my transfer case switching to 4 low. Was getting the flashing 4 lo so I took it in to a transmission place.
They came back to me and told me the same thing the dealership said they just replace the transfer case.
So after looking into it I decided to check the 4x4 actuator. I carefully removed the cover on the actuator.
To my amazement the little cam/ gear switch (looks like a gray lever) was missing. Wonder where it went? It actuator looked cleaned so they must of been opened it. . It's 2010 Toyota. Any ideas out there?

 

Photos would surely help.

There is a small switch gray with two dots on top in picture.
It contacts the cam.
The little lever that protrudes from switch.
That's what is missing.
That lever wasn't there just the black cilp to hold it in place.
Since this tundra has actually two actuators in one, one for 4 hi the other for 4 low They look like the same kind of switch.
Need one of these.
