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:
Some vehicles may experience a harsh 1-2 shift while driving under light throttle conditions. This may be caused by the Powertrain Control Module (PCM) calibration.
ACTION:
Reprogram the PCM. The revised calibration should reduce engine torque during the 1-2 shift to help improve the 1-2 shift feel. Refer to the Recalibration Cross Reference Chart for correct PCM calibration usage.
NOTE:
1997 ECONOLINE BUILT BEFORE 8/16/97 AND EQUIPPED WITH 5.4L ENGINE: ALSO INSTALL NEW INTERMEDIATE CLUTCH FRICTION PLATES (F75Z-7B164-SA) AND ACCUMULATOR (F6TZ-7G422-B) AND REPROGRAM THE PCM.
Perform normal diagnostics as outlined in the 1998 Econoline Workshop Manual and service as required. If the vehicle build date is before 1/12/98, and the concern is still present, reprogram the PCM.
NOTE:
PCM REPLACEMENT IS NOT AUTHORIZED BY THIS TSB. REFER TO THE POWERTRAIN CONTROL/EMISSIONS DIAGNOSIS (PC/ED) SERVICE MANUAL FOR APPROPRIATE DIAGNOSTIC PROCEDURES IF PCM HARDWARE CONCERNS EXIST.
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.
