Technical C6 governor Question for the auto trans guys

See attached photo. I'm rebuilding a C6 for my 59 f100, originally from a 75 f250 with a 390 and a C6. Thought the trans was untouched, but both primary and secondary valves in the governor have been modified. correct me if I am wrong if the larger valve is not the primary, which is shown. It is missing a spring between the valve and metal cover. Do I need this or is this a shift point mod. I drove the parts truck home, and chose to rebuild the trans due to a 1-2 shift flare. I am not doing any mod s to the 390, it will be a truck engine as is, into a truck

 

I did transmissions for Ford motor company for 40 years and if I’m not mistaken, and I may be because it’s been a while on a C6, I don’t think there’s a spring there. I seem to remember shaking the governor to make sure that valve was free and the other one you had to pick and move it against the spring. Also, if you’re not careful that snap ring can get*****ed when you blow it with air and cause that valve not to move.

 

The spring is missing.Don’t know why someone would remove it other than try and alter the shift points or they lost it.

 

Never seen one that had no spring, factory or altered.
No shift kits that I know of remove the spring all together.
Maybe a backyard trick?

I've known some backyard genius's, the parts truck had some signs that they were not involved. Short of another governor, any thoughts on a spring that can used, meaning the yellow spring from the valve body, as it fits. I'm shooting in the dark here, I know.

 

No, I would think you could get a complete governor from a local trans shop.
If you are not worried about full throttle shift points, most any C6 governor will work ok.
