The 1999 Dodge Ram 1500 doesn't have a governor in the traditional sense like older vehicles. The shift points and transmission operation are controlled electronically by the
Transmission Control Module (TCM). The TCM receives input from various sensors (speed sensor, throttle position sensor, etc.) and uses this information to determine the appropriate shift points.
Therefore, there's no single physical component you can point to and call a "governor." The function is integrated into the electronic control system.
