TCM REPROGRAM W/3.8L

TECHNICAL SERVICE BULLETIN

SERVICE INFORMATION

This service bulletin provides information related to the Transmission Control Module (TCM) upgrade for 2007-2009 Sorento (BL) models. Some 2007-2009 Sorento (BL) vehicles with a 3.8L engine may experience a "bumping" symptom during engagement of the damper clutch (torque converter lock-up clutch), and a "bucking" symptom when the damper clutch is fully engaged.

To correct this condition, the TCM should be reprogrammed using the GDS download as described in this bulletin.

Bumping	4th/5th gear	Vehicle Speed: 28~36 mph (4th gear); 42~45 mph (5th gear) Accelerator pedal depressed 18-22% (Slight acceleration) Engine Speed: 1300~1740 rpm
Bucking	4th gear	Vehicle Speed: 28~36 mph Accelerator pedal depressed below 10% (Constant speed) Engine Speed: 1100~1400 rpm
	5th gear	Vehicle Speed: 34~44 mph Accelerator pedal depressed below 10% (Constant speed) Engine Speed: 1100~1400 rpm

• This TCM software upgrade will optimize the lock-up operation in 4th and 5th gear.

1. Connect the power supply cable to the GDS tool.
   NOTE: If attempting to perform the TCM upgrade with the power supply cable disconnected from the GDS tool, be sure to check that the GDS tool is fully charged before TCM upgrade. If the GDS tool is not fully charged, failure to perform the TCM upgrade may occur. Therefore, it is strongly recommended that the power supply connector be connected to the GDS tool.
2. Connect the USB cable between the Vehicle Communications Interface (VCI) and the GDS tool.
   NOTE: When performing the TCM upgrade using the GDS tool, wireless communication between the VCI and GDS tool is not available. Therefore, be sure to connect the USB cable between the VCI and the GDS tool.
3. Connect the Main 16-pin DLC cable (GHDM - 241000) to the VCI.
4. Connect the Main 16-pin DLC cable (GHDM - 241000) to the OBD-II connector, located under the driver's side of the instrument panel.
5. With the ignition key ON, turn ON the VCI and GDS tool. Access the GDS vehicle identification number (VIN) screen and configure the vehicle using manual VIN entry.
   NOTE: Global Diagnostic System (GDS) users should access the "Notice" function from the GDS Main Screen for instructions regarding ECU upgrade events.
6. At the GDS Main Screen, select ECU UPGRADE from the menu buttons located on the bottom of the screen Next, select Auto Mode, AT  .
7. Perform the TCM upgrade in accordance with normal GDS tool ECU upgrade procedures.
   NOTE: Do NOT attempt to perform a Manual Mode TCM upgrade unless Auto Mode fails. Always follow the instructions given on the GDS tool in either Auto or Manual mode. See table for Manual Mode passwords. In addition, a TCM reset is required if Auto Mode fails; refer to the table below for procedure.
