Since no one answered yet the governor is what sets the shifts points. There
are two weights on centrifugally operated. One does the 1-2 upshift and the
other the 2-3. It is connected to the pinion shaft so it speed is directly
related to vehicle speed. The only failure I have seen in this part is
debris in one of the ports but that is usually not a temperature related
problem.

Not being able to upshift is usually in indication of the pressure problem.
The pump inlet screen may be restricted or one of the seals/pistons inside
the transmission is leaking internally until things warm up. Sometimes the
problem could be in the valve body. Most likely though you are looking at an
overhaul. If planning to have yours repaired the longer you wait the more it
may cost. If you wait until it starts to slip then you will start burning
things up. There is a pressure port and the Bentley does give some
troubleshooting information.

Can someone explain what this does.  I see it in Bentley but can't figure
out its function as part of the AT.  I'm wondering if it could be the
culprit in my tranny issue where it won't upshift to 3rd until warmed up.
