Got it. Its a detent spring and cap from the manual valve. There are two of them that oppose each other at the forward end of the manual shift valve, the right hand block in figure 74, page 25 of the Ultra service manual. You can see them in schematic in the fluid diagrams.

They are pressurized so that the car becomes harder to move from gear to gear at the selector the faster you go. This is one of my least favorite features.


In any event, you will need to replace the spring and cap and stake it in Place. Otherwise you will have a major governor pressure leak and consequently no upshifts.
