APPLICABLE MODEL(S)/VINS

DESCRIPTION
Some vehicles may experience excessive shift shock or a long time lag when shifting from P to R or from N to R. This is caused by miss learning of the TCM for shift timing. To correct the problem, the learning logic of the TCM has been changed.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Reboot the IDS to clear memory before reprogramming.
2. Using IDS IDS 81.05 or 82.01 or later software, reprogram the TCM to the latest calibration (refer to "Calibration Information" table) by following the "Module Reprogramming" procedure.
NOTE:
^ Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for TCM reprogramming.
^ It is not necessary to remove any fuses or relays during TCM reprogramming when the IDS screen prompts you to do so. You may accidentally stop power to one of the TCM terminals and cause the TCM to be blanked, or you may receive error messages during the IDS reprogramming procedure.
^ IDS shows the calibration part numbers after programming the TCM.
^ Please be aware that TCM calibration part numbers and file names listed in any Service Bulletin may change due to future releases of IDS software, and additional revisions made to those calibrations for service related concerns.
^ When reprogramming a TCM, IDS will always display the latest" calibration P/N available for that vehicle. If any calibration has been revised/updated to contain new information for a new service concern/issue, it will also contain all previously released calibrations.
^ When performing this procedure, we recommend using the "Power Supply" mode in the Battery Management System to keep the vehicle battery up to capacity. If a different charger is used, make sure it does not exceed 20 AMPS. If it exceeds 20 AMPS, it could damage the VCM.
3. After performing the TCM reprogramming procedure, verify the repair by starting the engine and making sure there are no MIL illumination or abnormal warning lights present.
NOTE:
^ If any DTCs should remain after performing DTC erase, diagnose the DTCs using MS3 online instructions or Workshop Manual section 01-02.
* ^ After reprogramming is complete, perform the Initial Learning Procedure. Refer to MS3 online instructions or Workshop Manual section 05-17 INITIAL LEARNING [FW6A-EL].*
