1996-1997 F SUPER DUTY

ISSUE:

Some vehicles may exhibit erratic 4-3 shift hunting while ascending a grade and/or no 3-4 upshift after cresting a grade. This may be due to the Powertrain Control Module (PCM) calibration.

ACTION:

Replace the PCM. The replacement PCM has a revised calibration to reduce the possibility of shift concerns. Refer to Section 03-14 of the appropriate F-Super Duty Powertrain/Drivetrain Service Manual.
