Randy's advice about dropping the pan is echoed in a Studebaker Service Bulletin from 1958. Titled "Adjusting Actuator-to-Transmission Control Valve Detent, Push Button Control", you'll find it in the article "Ultramatic Info from Studebaker STBs" archived at this site.

This bulletin further addresses complaints of the loss or delay of high range clutch application in the Ultramatic, which I have expereinced in one of my Patricians, but I have yet to try it.

This information may also have some merit WRT the subject problem as the focus of correction involves lining up the manual valve to the proper detents and indexing to the sector gear.
