QuestionI own a 2005 Chrysler 300 Touring RWD and I recently started to experience rough shifting. Too make a long story short, water was in my transmission so the tech recommended flushing the transmission. This helped with the shifting but it still does not shift completely smooth so the tech recommended driving the car for about 500-1000 miles to burn the moisture that is trapped.
My question is: Do you think that is a fair scope and is it possible that I may have some serious damage too the trans due too the water and what would you suggest my next step to try and resolve this issue.

DIAGNOSIS:
Using a Scan Tool (StarSCAN®) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all engine systems are functioning as designed. If DTC's are
present record them on the repair order and repair as necessary before proceeding further
with this bulletin.
Using the StarSCAN® read the transmission 2 - 4 Clutch Volume Index value. If the CVI
value is low (30 or below) proceed with the Repair Procedure. If the CVI is above 30,
further diagnosis may be required.

REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:
NOTE: When performing this Repair Procedure, the software release level in the
StarSCAN®; must be programmed with 7.02 level software or higher. The
software release level is visible in the blue header at the top of the
StarSCAN® screen.
NOTE: The StarSCAN® diagnostic scan tool fully supports Internet connectivity.
However, to take advantage of this feature you must first configure the
StarSCAN® for your dealership's network. Make sure the StarSCAN® is
configured to the dealership's network before proceeding. For instruction on
setting up your StarSCAN® for the dealer's network refer to either:
“DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online
Documentation”, or refer to the StarSCAN® Quick Start Networking Guide.
The StarSCAN® Quick Start Networking Guide is also available on the
www.dcctools.com website under the "Download Center".
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.

1. Install a battery charger and verify that the charging rate provides approximately 13.5
volts. Set the battery charger to continuous charge. Do not allow the charger to time
out during the flash process. Remove the charger from the battery when the flash
process is complete.
2. Connect the CH9410 StarSCAN® ethernet cable to the StarSCAN® and the dealer's
network drop.
3. Connect the CH9404 StarSCAN® vehicle cable to the StarSCAN® and the vehicle.
4. Power ON the StarSCAN®.
5. Retrieve the old PCM part number. Using the StarSCAN® at the “Home” screen:
a. Select “ECU View”
b. Touch the screen to highlight the appropriate ECU in the list of modules.
c. Select “More Options”
d. Select “ECU Flash”
e. Record the part number at the top of the “Flash PCM” screen for later reference.
f. Select “Browse for New File”. Follow the on screen instructions.
g. Select “Download to Scantool”.
h. Select “Close” after the download is complete, then select “Back”.
i. Highlight the listed calibration.
j. Select “Update Controller”. Follow on screen instructions.
k. When the update is complete, select “OK”.
l. Verify the part number at the top of the “Flash PCM” screen has updated to the new
part number.
NOTE: Due to the PCM programming procedure, a DTC may be set in other modules
(TCM, BCM, MIC, SKREEM, etc.) within the vehicle, if so equipped. Some
DTC's may cause the MIL to illuminate. From the “Home” screen select
“System View”. Then select “All DTCs”. Press “Clear All Stored DTCs” if
there are any DTCs shown on the list.
6. Using the StarSCAN® make sure all DTC's are cleared then perform a quicklearn
procedure to “relearn” all the transmission parameters prior to returning the vehicle to
the customer.
NOTE: The following step is required by law when reprogramming a PCM and/or
TCM.
7. Type the necessary information on the “Authorized Modification Label” p/n
04275086AB and attach near the VECI label (Fig. 1).
