REVISION NOTICE:
April 1, 2005: 2004 ± 2005 model year ES 330 vehicles have been added to
Applicable Vehicles. Introduction and Note have been updated on page 1.
Calibration Identification Chart has been updated to include ES 330 calibration IDs.
August 6, 2003: There has been a change in Warranty Time.
Previous versions of this TSIB should be discarded.
To improve the transmission shift feeling during specific operating modes, the Engine
Control Module (SAE term: Powertrain Control Module/PCM) calibration has been
revised. These improvements include:
Reduced downshift lag when accelerating at speeds from 10 to 20 mph.
Less gear hunting when driving on/off accelerator pedal at 20 to 30 mph
(for example: during heavy rush±hour traffic).
Improved response rate during heavy acceleration from a stop.
NOTE:
Version 12.01a or later Diagnostic Tester software is required to perform
this procedure.
Before proceeding, verify the ECM (PCM) calibration has NOT been updated by
checking for the Authorized Modifications Label (shown in step 1 of the
Repair Procedure).
Harsh ATM shifting may result if any Repair Procedure steps are omitted
(specifically steps 2 and 4 of ªFlash Reprogram ECMº on page 6).
2002 ± 2003 model year ES 300 vehicles.
2004 ± 2005 model year ES 330 vehicles.
