Ford made a protractor tool that was installed down next to the throttle lever on the transmission. There was also a tool to set the Z-bar linkage (another word for the throttle bellcrank behind the carburetor).

The protractor was also used to perform an operational pressure check to make sure the pressures were correct for idle and in the different gear selections. Most transmission shops just made due with what ever they had at hand but some may have purchased the tools. There were a couple of tools to adjust the bands too but there were other tools available at the time that would work on a lot of different transmissions. The 1935 to 53 Motors Manual has a lot of info in it about adjustments. The 1953 Merc-O-Matic Transmission Repair and Adjustment Manual is also a good one to have. It has a dark green cover with a light green back. I've seen them on flea-pay a time or two.
