Governor Pressure Curves
WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
There are four governor pressure curves programmed into the transmission control module. The different curves allow the control module to adjust governor pressure for varying conditions. One curve is used for operation when fluid temperature is at, or below 30°F. A second curve is used when fluid temperature is at, or above 50°F during normal city or highway driving. A third curve is used during wide open throttle operation. The fourth curve is used when driving with the transfer case in low range.
