RX8 2RTR-1.3L (2006)
Torque Converter: Customer Interest
Engine, A/T Controls - Vibration at 45-60 MPH
Bulletin No.: 05-007/08
Last Issued: 5/22/2008
Subject:
AT - VIBRATION AT 45-60 MPH DURING LIGHT ACCELERATION
APPLICABLE MODEL(S)/VINS
2006-2008 RX-8 vehicles equipped with 6-Speed AT
DESCRIPTION
Some customers may complain of body vibration occurring during light acceleration between 45-60 MPH (1600-1900 RPM). This symptom is caused by
resonance between the engine and the transmission and occurs during 6th gear lock-up.
^
As a mass-production change, PCM programming has been revised on vehicles with VIN JM1 FE**** ** 215479 and higher (built November 12,
2007 and after).
^
A revised torque converter with damper has been established to prevent vibration transfer to the transmission and body.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
NOTE:
Before performing the repair procedure, ensure service bulletin 5-010/06 - AT - SLIGHT SURGE WHILE DRIVING AT 40-55 MPH has
been completed if applicable.
1.
Verify customer concern.
2.
Verify vehicle VIN.
-
If VIN is lower than JM1 FE**** ** 215479 (built before November 12, 2007), go to STEP 3.
-
If VIN is JM1 FE**** ** 215479 or higher (built November 12, 2007 or after), go to STEP 6.
3.
Reboot the IDS to clear memory before reprogramming.
4.
Using IDS 51.6 or later software, reprogram the PCM 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 PCM reprogramming.
^
It is not necessary to remove any fuses or relays during PCM reprogramming when the IDS screen prompts you to do so. You may
accidentally stop power to one of the PCM terminals and cause the PCM to be blanked, or you may receive error messages during the IDS
reprogramming procedure.
^
IDS shows the calibration part numbers after programming the PCM.
^
Please be aware that PCM 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 PCM, 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 that a battery charger be installed on the vehicle battery and turned ON to a maximum
charge of no more than 20 AMPS to keep the vehicle battery up to capacity. If you exceed 20 AMPS, it could damage the VCM.
5.
After performing the PCM reprogramming procedure, verify the repair by starting the engine and making sure there are no MIL illumination or
abnormal warning lights present.
