Introduction
Some customers may experience a shift flare that is most noticeable after a cold soak under the following operating conditions:
^ 3rd to 4th upshift during the first 10 minutes of operation
^ 2nd to 3rd and/or 4th to 5th upshift
^ 5th to 4th downshift when accelerating from coast or decelerating between 30 - 40 mph
The Transmission Control Module (TCM) logic has been revised to help improve these specific customer concerns. In the event the reflash does NOT completely resolve the issue, the automatic transaxle assembly should also be replaced.
Applicable Vehicles
^ 2007 model year Camry ("6) vehicles produced BEFORE the Production Change Effective VINs shown below.

Calibration Identification Chart
Repair Procedure
1. Check for the Authorized Modifications Label affixed to the vehicle in the location shown in Figure 1. Confirm if the TCM calibration has been updated. If the calibration ID listed is NOT the latest TCM calibration go to step 2.
2. Allow the vehicle to cold soak for a minimum of 4 hours.
3. Connect TIS Techstream to DLC3.
4. Turn the engine switch ON.
5. Turn the TIS Techstream tester ON.
6. Enter the following menus on the tester: Vehicle / ECT / Data List.
7. Start the engine.
8. Test drive the vehicle to duplicate the customer's concern.
If one of the shift flares described in this TSB occurs, flash reprogram the TCM.
9. Flash reprogram the TCM.
NOTE:
^ The GR8 Battery Diagnostic Station MUST be used in Power Supply Mode to maintain battery voltage at 13.5 volts while flash reprogramming the vehicle.
^ For details on how to use the GR8 Battery Diagnostic Station, refer to the GR8 Instruction Manual located on TIS, Diagnostics - Battery.
Follow the procedures outlined in TSB No. SS002-07, "Techstream ECU Flash Reprogramming Procedure, " and flash the ECM (PCM) with the NEW calibration file update.
10. Start the engine and warm it up to normal operating temperature before test-driving.
11. Allow the vehicle to cold soak for a minimum of 4 hours.
12. Test-drive the vehicle to confirm proper vehicle operation.
13. If the condition still exists, remove and replace the automatic transaxle assembly w/torque converter.
NOTE:
When the automatic transaxle is replaced, the transaxle compensation code MUST be input into the TCM. After the automatic transaxle is reinstalled, the QR code label will be positioned where the code cannot be read. Record the transaxle compensation code BEFORE reinstalling the automatic transaxle.
14. After replacement of the transaxle assembly w/torque converter enter the new transaxle compensation code.
Refer to TSB No. TC003-06, "U660E Automatic Transaxle Compensation Code Input Process".
15. Install the Authorized Modifications Label.

^ TCM part number: [Refer to the Parts Information section for the CURRENT PART NUMBER]
^ Calibration ID(s): [Refer to the Calibration Identification Chart for the NEW CALIBRATION ID]
^ Dealer Code
^ Repair Date
^ Change Authority (this TSB number): TC007-07
