Early mechanical/hydraulic transmission controls use inputs from the throttle linkage and a mechanical governor mounted on the transmission output shaft to automatically select gear ratios. To illustrate the basic concept, hydraulic pressure from the governor pushes the 1-2 shift valve from 1st gear to the 2nd gear ratio as vehicle speed increases.
