For clarification: I've heard of folks using a lever mounted behind the transmission to control the shift rail lever on the transmission. The original installation in my 1951 Mercury had the cable control mounted on the underside of the dash. Pull out on the cable for direct drive and push in for overdrive. The rail control lever on the transmission it set so it is aimed down toward the ground. It's not hard to figure that pulling the cable moves the lever forward and pushing it in moves it aft. This lever can be removed from the OD unit and installed with the lever pointing up. When this is done, the operation of the lever is in reverse of the normal position. I've seen them placed this way so that a lever and rod linkage could be used to control it for preference of the operator related to the position of the lever behind the transmission.

A person can run into all sorts of modifications on these old cars.
