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 exhibit a harsh 1-2 upshift during light throttle. This may be caused by the high capacity of the intermediate clutch.
ACTION:
Install new intermediate clutch friction plates and accumulator body and reprogram the Powertrain Control Module (PCM). The new friction plates change the friction coefficient and, combined with the revised PCM calibration, should result in an improved 1-2 upshift. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1. Perform normal diagnostics as outlined in the 1997 Econoline Workshop Manual and service as required.
2. If the concern is still present and the vehicle was built before 8/16/97, install new intermediate clutch Friction Plates (F75Z-7B1 64-BA) and Accumulator Body (F75Z-7G422-AA) and reprogram the PCM. Refer to the PCM Application Chart for correct PCM and calibration usage.
NOTE:
REGIONAL APPROVAL MUST BE OBTAINED WHEN IT IS NECESSARY TO REPLACE THE PCM. EMERGENCY ORDERS ONLY WILL BE FILLED BECAUSE SHELF STOCK OF PCMs ARE LIMITED.
3. Follow all normal service procedures as outlined in the Workshop Manual for transmission disassembly and reassembly.
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.
