WARNING:
THIS MODIFICATION IS AUTHORIZED ONLY FOR THE LISTED ENGINE. PERFORMING THIS MODIFICATION ON OTHER ENGINE
CALIBRATIONS IS UNAUTHORIZED AND COULD CREATE LIABILITY UNDER APPLICABLE FEDERAL OR LOCAL LAWS.
ISSUE:
Hesitation/surge may be present on some vehicles at speeds of 56-72 km/h (35-45 mph) in all ambient temperatures. A delayed cold transmission
engagement from reverse to drive may also occur. This may be due to the Exhaust Gas Recirculation (EGR) calibration.
ACTION:
Reprogram the Powertrain Control Module (PCM). The new calibration should reduce the possibility of hesitation/surge and delayed engagement. Refer
to the following PCM Application Chart for correct PCM calibrations.
Obtain an Authorized Modification Decal (FPS 8262 - obtainable through DOES II, 25/pkg) and list the date, dealer number, and summary of
modifications performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized
Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
