illumination on vehicles equipped with a 948TE 9 speed automatic transmission (sales
code DFH or DFJ). Upon further investigation, a technician may find Diagnostic Trouble
Code (DTC) P1DAD - Input Shaft-Output Shaft Direction Correlation stored in the TCM
memory.**
In addition to addressing the above DTC, this TCM calibration update is being released to
enable the new wiTECH based “Transmission Quick Learn” procedure to be performed
anytime the transmission adaptation memory cells are cleared or when addressing
customer concerns of poor shift quality. It is also being released to improve transmission
downshift response time during normal driving.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all vehicle systems are functioning as designed. If DTCs or
symptom conditions, other than the ones listed above are present, record the issues on the
repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes the symptom/condition listed above or if the technician finds the
DTC, perform the Repair Procedure.
REPAIR PROCEDURE:
CAUTION: The Powertrain Control Module must be updated to the latest available
software to allow the quick learn procedure to function. Refer to all
applicable published service bulletins for detailed repair procedures and
labor times regarding updating the PCM software.
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2
volts. Do not allow the charging voltage to climb above 13.5 volts during the
flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
1. Reprogram the TCM with the latest available software. Detailed instructions for
flashing control modules using the wiTECH Diagnostic Application are available by
selecting the “HELP” tab on the upper portion of the wiTECH window, then “HELP
CONTENTS.” This will open the Welcome to wiTECH Help screen where help topics
can be selected.
2. Using wiTECH, Perform the TCM “VIN Verification” routine Located in the TCM “Misc
Functions” menu and follow the on-screen prompts.
3. Using wiTECH, perform a “PROXI Configuration Alignment” routine located in the
“Vehicle Preparations” tab on the main vehicle view screen .
4. Turn the ignition off and disconnect wiTECH for 1 minute.
5. Turn the ignition back on and reconnect wiTECH.
6. From the vehicle view screen, select “PROXI Configuration Alignment” routine again in
the “Vehicle Preparations” tab and verify all modules are properly aligned.
7. Clear all DTCs that may have been set in any module due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow them
to be cleared.. Proceed to Step #8.

CAUTION: The Powertrain Control Module must be updated to the latest available
software to allow the quick learn procedure to function. Refer to all
applicable published service bulletins for detailed repair procedures and
labor times regarding updating the PCM software.
NOTE: This flash will clear the transmission adaptive values which requires the
“Transmission Quick Learn” procedure to be performed.
8. Start the engine and monitor the transmission temperature on the Electronic Vehicle
Information Center (EVIC).
9. With the vehicle located in a suitable area, allow the transmission to warm up to
minimum of 60°C (140°F) by performing the following steps:
a. Apply the service brake.
b. Shift Transmission from Park to Reverse.
c. Shift Transmission from Reverse to Drive.
d. Accelerate the vehicle to minimum of 45 mph to allow the transmission to cycle
through each gear.
e. Continue to drive the vehicle until the transmission temperature reaches 60°C
(140°F).
NOTE: If the vehicle is equipped with the start/stop feature (sales code XBU) it must
be disabled prior to performing this procedure. To disable, press the on/off
switch located on the center switch bank near the HVAC controls.
10. Connect wiTECH diagnostic scan too to the vehicle.
11. Check for active TCM DTCs. Do not perform the Quick Learn procedure if TCM DTCs
are present. Repair transmission as required.
12. Select the TCM module in wiTECH.
13. Select the “Misc Functions” tab.
NOTE: If the “Quick Learn” option does not appear on wiTECH and both the TCM
and PCM were just updated, restart the wiTECH application which should
now be populated with the “Quick Learn” option.
14. Select the “Quick Learn” procedure, and follow the on-screen instructions to reset and
learn the clutch adaptive values.
15. Shift the transmission into Park and shut off the engine. The procedure is now
complete.
