takes for the gear ratio to change following a shift request, the TCM can determine the volume of fluid used to apply or release a friction element.
The volume of transmission fluid needed to apply the friction elements are continuously updated for adaptive controls. As friction material wears, the
volume of fluid need to apply the element increases.
Certain mechanical problems within the input clutch assembly can cause inadequate or out-of-range element volumes. Also, defective Input/Output
Speed Sensors and wiring can cause these conditions. The following charts identifies the appropriate clutch volumes and when they are
monitored/updated:
42RLE
545RFE
SHIFT SCHEDULES
As mentioned earlier, the TCM has programming that allows 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 level
As driving conditions change, the TCM appropriately adjusts the shift schedule. Refer to the following chart to determine the appropriate operation
expected, depending on driving conditions.
