Automatic Transaxle Shift Hesitation/Engine Flare During 2-3 Shift at Light Throttle and/or Harsh Reverse to Drive Shift, Both at Cold Operating Temperatures (Reprogram Transaxle Control Module (TCM))

Some customers may comment on a hesitation/engine flare during the 2-3 shift and/or a harsh reverse to drive garage shift, both at cold operating temperatures.

Diagnosis may show a false power steering code DTC C0000 set with NO service vehicle soon light on.

The TCM calibration may be the cause.

1. Reprogram the Transaxle Control Module (TCM) with a new service calibration released with TIS satellite data update version 11.25 on November 15, 2004 or newer. Refer to Service Programming System (SPS) (Document ID #1265170).

Important: 

•	An in-depth road test drive procedure is required to allow the TCM to adapt/"fine tune" the software calibrations to the transaxle in order to achieve optimum performance and shift characteristics.

•

If any of the road test/relearn procedure is not completed as outlined during the service visit to the dealership, it is possible that the customer may experience a less than desired or uncharacteristic shift quality for that certain shift point until the adaptive values for that shift are adapted by the TCM .

•	This "uncharacteristic shift quality" should not be misunderstood as an internal transaxle concern unless the concern continues after the complete relearn procedure has been completed .

2. Perform the transmission adaptive learn procedure. Refer to Transmission Adaptive Learn Procedure (SI Document ID #1471191).
