Important: Shift speed points are affected by many different vehicle and transmission operating conditions. The table above represents shift speed points calibrated at specific throttle angles during normal operating conditions and a temperature range between 0-130°C (32-266°F). These shift speed points are also based on an effective final drive ratio of 2.77, and assume a production-intent tire size.

To assist in monitoring the different variables, the respective scan tool data parameter is also listed.
