assembly, etc.) can cause inadequate or out-of-range clutch volumes. Also, defective Input/Output Speed Sensors and wiring can cause these conditions.
The following chart identifies the appropriate clutch volumes and when they are monitored/updated:
TRANSMISSION SHIFT SCHEDULES
The PCM is programmed to allow it to select a variety of shift schedules. Shift schedule selection is dependent on the following:
-
Shift lever position
-
Throttle position
-
Engine load
-
Fluid temperature
-
Software calibration level
As driving conditions change, the PCM appropriately adjusts the shift schedule. Refer to the following chart to determine the appropriate operation
expected, depending on driving conditions.
5 Volt Supply - PCM Output
5 VOLT SUPPLY - PCM OUTPUT
The PCM supplies two regulated 5 volts supplies - a 5V primary and a 5V secondary (auxiliary) to the following sensors:
-
Camshaft Position Sensor (5V secondary)
-
Crankshaft Position Sensor (5V primary)
-
EGR Position feedback sensor (5V secondary) (if equipped)
-
Engine coolant temperature sensor (connected to 5V internal via a pullup resistor)
-
Inlet Air Temperature Sensor (connected to 5V internal via a pullup resistor)
