THIS PROGRAM IS IN EFFECT UNTIL OCTOBER 31, 2011.
Condition
Certain 2008-09 Chevrolet Tahoe and GMC Yukon; 2009 Cadillac Escalade, Chevrolet Silverado, and GMC Sierra vehicles, equipped with a Two-Mode Hybrid Transmission (RPO M99), may have a condition in which excessive pressure on the transmission clutch could cause a fracture. This may result in an improper transmission shift when shifting from third to fourth gear. It may also cause the engine to run at a higher RPM, reduce fuel economy, and illuminate the Service Engine Soon light.
Correction
Dealers are to reprogram the transmission controller to reduce the clutch pressure. Some vehicles will also require the replacement of the control solenoid valve.
Vehicles Involved
Involved are certain 2008-09 Chevrolet Tahoe and GMC Yukon; 2009 Cadillac Escalade, Chevrolet Silverado, and GMC Sierra vehicles, equipped with a Two-Mode Hybrid Transmission (RPO M99), and built within these VIN breakpoints:
Important
Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Required Field Actions section in the Global Warranty system. Not all vehicles within the above breakpoints may be involved.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.
Parts Information
No parts are required for the majority of vehicles. 44 vehicles will require replacement of the control solenoid valve (transmission controller) (see list below for listing of vehicles). Assemblies required to complete this program are to be obtained from General Motors Customer Care and Aftersales (GMCC&A). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.
Service Procedure
Refer to Programming and TEHCM Replacement Decision Table below.
TEHCM Programming
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 Multiple Diagnostic Interface (MDI) and TIS2WEB with the calibration update. Use TIS2WEB on or after October 6, 2009 to obtain the calibration. If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.
For step-by-step programming instructions, please refer to SI and the Techline Information System (TIS) terminal.
1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Only use an approved Midtronic 165-PSC charger to maintain proper battery voltage during programming.
2. Perform sequential programming event. Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
1. Connect the MDI to the vehicle. Use a wire connection with MDI for this programming event. DO NOT use the MDI wireless option.
2. Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen.
3. Select SEQ EBCM/HCP/ECM/TCM/BECM Sequential Programming from the Supported Controllers screen. Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
4. Follow the on-screen instructions.
3. Using the MDI and Tech 2(R), clear all DTCs if required.
Courtesy Transportation - For US and Canada
The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranties. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.
