The 1998 Dodge Ram 1500 doesn't have a traditional, externally adjustable transmission governor in the way older vehicles did. The shift points and transmission operation are controlled electronically by the
Transmission Control Module (TCM). This module receives inputs from various sensors (speed sensor, throttle position sensor, etc.) and uses that information to manage the transmission's behavior. The TCM itself is typically located under the dashboard or in the engine compartment, but its exact location varies slightly depending on the specific trim level and options of the truck.
You won't find a physical governor to adjust. Any changes to shift points or transmission behavior would be done through a computer scan tool capable of accessing and modifying the TCM's parameters.
