channels line pressure to the solenoid valve through the governor body. It also channels governor pressure from the solenoid valve to the governor
circuit. It is the solenoid valve that develops the necessary governor pressure.
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, 10° 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.
