Service Update for Inventory and Customer Vehicles-Improved Transmission Control Calibrations-Expires with Base Warranty

THIS BULLETIN IS BEING REVISED TO CORRECT THE SATURN CLAIM INFORMATION CASE TYPE. SATURN U.S. RETAILERS SHOULD USE A "VC" CASE TYPE WHEN SUBMITTING A CLAIM. PLEASE DISCARD ALL COPIES OF 07058, ISSUED MARCH 2007.

THIS SERVICE UPDATE INCLUDES VEHICLES IN DEALER/RETAILER INVENTORY AND CUSTOMER VEHICLES THAT RETURN FOR ANY TYPE OF SERVICE, AND WILL EXPIRE AT THE END OF THE INVOLVED VEHICLE'S NEW VEHICLE LIMITED WARRANTY PERIOD.

This bulletin provides a procedure to reprogram the Transmission Control Module (TCM) on certain 2007 GMC Acadia and Saturn Outlook vehicles. Revised TCM calibrations have been developed which improve shift responsiveness and customer satisfaction.

This service procedure should be completed as soon as possible on involved vehicles currently in dealer/retailer inventory and customer vehicles that return to the dealer/retailer for any type of service during the New Vehicle Limited Warranty coverage period.

A list of involved vehicles currently in dealer/retailer inventory is available on the "Service Update Bulletin Information" link under the service tab in DealerWorld (GM and Saturn US), or attached to the Dealer Communication (Canada), used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty, and are within the VIN breakpoints provided below, should be checked for vehicle eligibility in the appropriate system listed below.

Important:  Dealers/retailers are to confirm vehicle eligibility prior to beginning repairs by using the system(s) below. Not all vehicles within the above breakpoints may be involved.

-- GM dealers and Canadian Saturn retailers should use GMVIS.

-- US Saturn retailers should use the AS/400 system.

Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2® scan tool and the Techline Information System (TIS) 2000 terminal with the calibration update. Use data version 3.0 for 2007 or later, available on TIS 2 Web (website version of TIS) March 9, 2007; and on TIS DVD version 4.0 / 2007 or later, mailed to dealers beginning April 11, 2007. Contact the Techline Customer Support Center at 1-800-828-6860 English or 1-800-503-3222 French to obtain the correct calibration until the February 18, 2007 TIS 2 Web update.

The "Required Field Actions" section of the GM Vehicle Inquiry System (GMVIS) must be checked to determine if a specific vehicle requires this action. If GMVIS indicates that Service Update Bulletin 07058 remains ‘open’ and TCM reprogramming has not taken place, reprogram the TCM using a Tech 2® scan tool with the calibration update from Techline Information System (TIS).

Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming. Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed.

The ignition switch must be in the proper position. The Tech 2® prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.

Make certain all tool connections are secure, including the following components and circuits:

DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.

DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date.

Tech 2 Pass-Thru Method

1. Verify the battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming.
2. Connect the Tech 2® to the vehicle and the TIS terminal.
3. Turn the ignition to on with the engine off.
4. After all warning chimes inside the vehicle have stopped, turn on the Tech 2.
5. On the TIS terminal go into SPS Programming.
6. In the top box Select Diagnostic Tool select Tech 2 Legacy Pass-Thru.
7. In the lower box Select Programming Process select Reprogram ECU.
8. Follow instruction on the TIS terminal. When you get to the Supported Controllers screen.

8.1.	In the top box select TCM, Transmission Control Module.

8.2.	In the lower box select Normal.

8.3.	Select Next.

9. Select NEXT when the calibrations screen displays.
10. Follow on screen prompts until programming is completed.
11. When programming is complete:

11.1.

Turn off Tech 2.

11.2.

Turn off ignition switch.

12. Wait 30 seconds.
13. Turn ignition switch to on with engine off.
14. Turn on the Tech 2.
15. Go into diagnostics and check for DTC codes.
