| NO TRANSMISSION DOWNSHIFT IN TOW/HAUL MODE – BUILT ON OR BEFORE 6/20/2016 | |
| Publication Date: August 15, 2016 | |
ISSUE:
Some 2016-2017 F-53 Motorhome Chassis and F-59 Commercial Stripped Chassis vehicles equipped with a 6.8L engine and built on or before 6/20/2016 may exhibit a no transmission downshift when descending a grade in Tow/Haul mode.
ACTION:
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
- Check the vehicle build date. Was the vehicle built on or before 6/20/2016 and the fourth position of the vehicle identification number (VIN) a numeric 4 or 5? Refer to Workshop Manual (WSM), Section 100-01.
- Yes – reprogram the powertrain control module (PCM) to the latest calibration using IDS release 101.03 or higher. Make sure you are connected to the internet when entering module programming to obtain the latest updates. Calibration files may also be obtained at www.motorcraftservice.com.
- No – this article does not apply. Refer to WSM, Section 307-01 for normal diagnostics.
NOTE: 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.

Service Information & Reprogramming
Software necessary to program electronic modules to the latest calibration level, perform module initialization (PATS), and set Programmable Parameters on Ford
, Lincoln and Mercury vehicles.
Ford Module Programming (FMP) is a software application that allows subscribers to program electronic modules on Ford, Lincoln and Mercury vehicles. It can be used for:
- Reprogramming emission-related (OBDII) modules on some vehicles manufactured in 1995 and all vehicles manufactured from 1996 to the present
- Reprogramming or reconfiguring non-emission-related modules on many vehicles (UBP and MS-CAN not supported)
In addition, module initialization (PATS) functions such as Keycode Erase/Reprogram and PCM Parameter Reset can be done using this application.
J2534 Device 
using Ford Module Programming (FMP) can Reprogram and Configure most Modules.
