ISSUE:

Some F-Super Duty F-250-450 pickup truck vehicles equipped with a 6.7L diesel engine and built on or before 5/16/2012 may experience an engine shudder with or without turbo flutter noise around 900-1400 RPM with steady throttle. The issue may be more noticeable at high elevation, high ambient temperature and/or when driving up a slight incline. The concern is not present during regeneration or while using cruise control. Some vehicles that exhibit the concern may set diagnostic trouble code (DTC) P0299.

ACTION:

Follow the Service Procedure to diagnose this concern.

SERVICE PROCEDURE

Check all continuous memory diagnostic trouble codes (CMDTCs). Are any DTCs present other than the P0299?
1. Yes - This article does not apply, refer to Powertrain Control/Emission Diagnostic (PC/ED) Manual and continue with normal diagnostics.
2. No - Proceed to Step 2.

Reprogram the powertrain control module (PCM) to the latest calibration using IDS release 83.01 and higher. Calibration files may also be obtained at www.motorcraft.com.

NOTE: SOME LIGHT SURGE CONDITIONS (I.E. ENGINE LUGGING) MAY STILL BE PRESENT UNDER CERTAIN ENGINE LOAD AND DRIVING CONDITIONS AFTER PCM RECALIBRATION. THIS IS A NORMAL CHARACTERISTIC DUE TO CUSTOMER DRIVING HABITS AND INCREASED THROTTLE INPUT MAY BE REQUIRED IN THESE SITUATIONS.

NOTE: PLEASE ADVISE THE CUSTOMER THAT THIS VEHICLE IS EQUIPPED WITH AN ADAPTIVE TRANSMISSION SHIFT STRATEGY WHICH ALLOWS THE VEHICLE'S COMPUTER TO LEARN THE TRANSMISSION'S UNIQUE PARAMETERS AND IMPROVE SHIFT QUALITY. WHEN THE ADAPTIVE STRATEGY IS RESET, THE COMPUTER WILL BEGIN A RE-LEARNING PROCESS. THIS RE-LEARNING PROCESS MAY RESULT IN FIRMER THAN NORMAL UPSHIFTS AND DOWNSHIFTS FOR SEVERAL DAYS.
