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.
