It's part of the Engine Control Module.
A vital component of any diesel engine system is the governor, which limits the speed of the engine by controlling the rate of fuel delivery.*Diesel engine speed is controlled solely by the amount of fuel injected into the engine by the injectors. Because a diesel engine is not self-speed-limiting, it requires not only a means of changing engine speed (throttle control) but also a means of maintaining the desired speed. The governor provides the engine with the feedback mechanism to change speed as needed and to maintain a speed once reached. A governor is essentially a speed-sensitive device, designed to maintain a constant engine speed regardless of load variation. Since all governors used on diesel engines control engine speed through the regulation of the quantity of fuel delivered to the cylinders, these governors may be classified as speed-regulating governors. As with the engines themselves there are many types and variations of governors. In this module, only the common mechanical-hydraulic type governor will be reviewed. The major function of the governor is determined by the application of the engine. In an engine that is required to come up and run at only a single speed regardless of load, the governor is called a constant-speed type governor. If the engine is manually controlled, or controlled by an outside device with engine speed being controlled over a range, the governor is called a variable- speed type governor. If the engine governor is designed to keep the engine speed above a minimum and below a maximum, then the governor is a speed-limiting type. The last category of governor is the load limiting type. This type of governor limits fuel to ensure that the engine is not loaded above a specified limit. Note that many governors act to perform several of these functions simultaneously.
No, you need the actual software to do this (e.g., Insite for Cummins, Davie for PACCAR, DDEC for Detroit Diesel, etc).
Duramax is a diesel motor. Most diesels have a built in governor to keep the engine speed from going too high. I suspect that the engine is hitting the top speed and the governor is kicking in just before you shift.
A variable speed governor is an engine part that works with the engine to govern speeds required within the engine. It serves to keep the engine at a steady speed as set by the operator of the vehicle.

A governor is a mechanical device in the injection pump on older diesels. The accelerator pedal does not control the amount of fuel into the engine - it commands the engine to run at a certain speed. The governor controls the position of the fuel rack in the pump to control the volume of fuel injected in each cylinder. Newer diesels do the same thing in software. No mechanical governor exists. The pedal is connected to a position sensor; the injectors are computer controlled. The engine and vehicle speed limiters are in software also.
By reprogramming the engine ECM.
Speed is computer controlled and there is no governor that you can remove.
The engine computer does act as a speed limiter.
Add a governor to limit the speed of the engine or vehicle.
