General Information and Procedures

Perform road test following sequence given by Tech 1 or other scan tool. MPH shift points will vary with actual throttle position and driver habits.

Shift speed charts have been updated to reference throttle angle or (TPS) data to make measurements more uniform and accurate. A scan tool is necessary to monitor throttle angle.




Refer to band range application chart as an aid in diagnosing driveability problems.
