9 T-SB June 4, Page 9 of 13 Repair Procedure 1. Test drive vehicle and confirm condition. 2. Check the transmission for evidence of fluid leakage. 3. Check the transmission fluid level. While checking, collect a very small amount of ATF in a clean container when fluid overflows. Refer to the Technical Information System (TIS), applicable model and model year Repair Manual: 2008 Sequoia: Transmission/Transaxle: Automatic Transmission Fluid: Adjustment Sequoia: Transmission/Transaxle: Automatic Transmission Fluid: Adjustment 2007 Tundra: Transmission: Automatic Transmission Fluid: Adjustment 2008 Tundra: Transmission: Automatic Transmission Fluid: Adjustment Tundra: Transmission: Automatic Transmission Fluid: Adjustment Incorrectly adjusted fluid level can cause transmission shifting issues, including no vehicle movement, slipping, and/or M.I.L. ON conditions. Is the transmission fluid level correct? YES Go to step 4. NO Adjust transmission fluid level to correct level then test drive vehicle to confirm if condition is eliminated. If condition is eliminated, return vehicle to customer. If condition is NOT eliminated, go to step 4.

10 T-SB June 4, Page 10 of 13 Repair Procedure (Continued) 4. Examine the small sample of transmission fluid collected during fluid level check. Does the transmission fluid smell burnt or have gritty black particles? It is normal for WS transmission fluid to change from a clear red color when new to an opaque brown color with use. YES Go to step 5. NO This TSB does NOT apply. Follow diagnostics for automatic transmission in applicable Repair Manual. 5. Replace the transmission.

12 T-SB June 4, Page 12 of 13 Repair Procedure (Continued) 7. Check for the Authorized Modifications Label affixed to the vehicle in the location shown in Figure 1. Confirm if the ECM (PCM) calibration has been updated. If the calibration ID listed is NOT the latest ECM (PCM) calibration go to step 8. Figure 1. Location of Authorized Modifications Label on 2008 Sequoia and Tundra 1 Replacement ECM (PCM) Part Number (i.e., CD41) 2 New Calibration ID(s) (i.e., 30CA8100) 4 Date Completed 5 This TSB Number 3 Dealer Code 8. Flash Reprogram the ECM (PCM). 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 the Technical Information System (TIS), Diagnostics Battery. Follow the procedures outlined in TSB. SS002-07, Techstream ECU Flash Reprogramming Procedure, and flash the ECM (PCM) with the NEW calibration file update.

13 T-SB June 4, Page 13 of 13 Repair Procedure (Continued) 9. Start the engine and warm it up to normal operating temperature before test driving. 10. Test drive the vehicle to confirm proper vehicle operation. 11. Install the Authorized Modifications Label. A. Using a permanent marker, enter the following information on the label: ECM 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] B. Affix the Authorized Modifications Label to the vehicle at the location shown in Figure 1. The Authorized Modifications Label is available through the MDC, P/N LBL.
