SUBJECT:
Flash: Shift Hesitation During Wide Open Throttle
NOTE:
THE StarSCAN must be operating at version 6.01 or higher when the module is reprogrammed.
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Transmission Control Module (TCM) with new software.
MODELS:
2005 - 2006
(LX)
Chrysler 300, Magnum, Charger SRT-8
NOTE:
This bulletin applies to vehicles equipped with a 6.1 L engine (sales code ESF) and a NAG1 automatic transmission (sales code DGJ) built on or
before July 25, 2005 (MDH 0725XX).
DISCUSSION:
Randomly during a wide open throttle condition the engine RPM goes beyond the fuel cutoff point before the 1-2 upshift is made. This causes a short
hard bump at the beginning of the shift. It is more likely to occur if the vehicle is traveling around 15 MPH and then the throttle is pushed to wide open
(WOT).
This condition is caused by the TCM not being able to calculate the correct engine speed at which to initiate the shift.
NOTE:
There are two methods to download flash files to StarSCAN. The first method (NEW) is to download the flash files to the StarSCAN from the
internet. The second method is to download the flash files from the StarSCAN Software Update CD.
