Shift Schedules

WARNING: This page is about a different car, the 2004 Dodge Pickup and 2004 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

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 SHIFT SCHEDULES CHART  to determine the appropriate operation expected, depending on driving conditions.
