Part throttle kickdown setup.

Oh, that's so weird.
I have to wonder if someone removed it to use on something else, but they would have had to put the plate back on with the shorter screws like a non PT 904 or 727.
The other halve of the valve body has the electrical stand that goes up through the case though?

This is an RE body, but the RH still has this electrical connector (but with only 3 pins)

Yes, it has the two solinoids for o/d and lockup, and the the 3 pin connector that sticks up through the case.
