SYMPTOM/CONDITION:

The following 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 other

conditions are present, record them on the repair order and repair as necessary before

proceeding further with this bulletin.

If a customer’s VIN is listed in VIP or your RRT VIN list, perform the repair. For all other

customers that describe the symptom/condition or if the technician finds the listed 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. Using wiTECH, check the TCM calibration and see if it is up to date. Does the TCM

software need to be updated?

a. Yes>>> Proceed to Step #2.

b. No>>> This TSB does not apply. Use labor op 18-19-05-T9 to close out the RRT

portion of this service bulletin.

2. Reprogram the TCM with the latest 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.

NOTE: After reprogramming, the following must be performed.

3. Using wiTECH, Perform the TCM “VIN Verification” routine Located in the TCM “Misc

Functions” menu and follow the on-screen prompts.

8. Clear any DTCs that may have been set in any modules due to reprogramming. The

wiTECH application will automatically present all DTCs after the flash and allow the

tech to clear them. Proceed to Step #9.

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.

9. Start the engine and monitor the transmission temperature on the Electronic Vehicle

Information Center (EVIC).

10. 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.

11. Connect wiTECH diagnostic scan too to the vehicle.

12. Check for active TCM DTCs (Diagnostic Trouble Codes). Do not perform the Quick

Learn procedure if TCM DTCs are present. Repair transmission as required.

13. Select the TCM module in wiTECH.

14. 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.

15. Select the “Quick Learn” procedure, and follow the on-screen instructions to reset and

learn the clutch adaptive values.

16. Shift the transmission into Park and shut off the engine. The procedure is now
