Governor Pressure Curves
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, 1°C (30°F). A second curve is used when fluid temperature is
at, or above, 100°C (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.
