TSB #: 21-020-06
Date: December 20, 2006
Subject: Flash: SRT8 - Delayed Or Rough 1-2 shift at Wide Open Throttle After Kickdown
Overview: This bulletin involves selectively erasing and reprogramming the Transmission Control Module (TCM) with new software.
Models: ALL 2005-2006 SRT8 models of the 300C, Charger, Magnum and Grand Cherokee (North America and International Markets).
Symptom/Condition: The customer may experience a delayed 1-2 shift at wide open throttle after a kickdown. This is often referred to as a harsh or jerky shift which is the result of the engine reaching the maximum engine speed fuel cut off prior to the transmission shifting.
Note: This flash will also change the strategy for the “Autostick” feature. This version will allow the transmission to upshift when the maximum engine speed is reached. The previous version would not allow the upshift unless the driver selected the next gear. Once the flash is performed, all of the changes are permanent and cannot be reversed.
