SUBJECT: Flash: Transmission Shift And Drivability Enhancements OVERVIEW: This bulletin involves reprogramming the Transmission Control Module (TCM) with the latest available software. MODELS: 2015 (LA) Dodge Challenger NOTE: This bulletin applies to vehicles built on or before March 6, 2015 (MDH 0306XX) equipped with the following options: • 6.2L engine (sales code ESD) and equipped with an 8HP90 transmission (sales code DFE). • 6.4L engine (sales code ESG) and equipped with an 8HP70 transmission (sales code DFK). SYMPTOM/CONDITION: A small number of customers may experience one or more of the following concerns. These concerns are broken up per engine and transmission combination. 6.2L engine (sales code ESD) equipped with an 8HP90 transmission (sales code DFE) • • • • Transmission will not upshift during Wide Open Throttle (WOT) acceleration. Harsh or inconsistent coasting downshifts. Transmission will not shift into 7th gear during high speed driving. Inconsistent or busy shifts during stop and go traffic. 21-009-15 REV. A • • -2- Inconsistent gear shift patterns when driving on grades. Malfunction Indicator Lamp (MIL) Illumination during ABS activated stops with Diagnostic Trouble Code (DTC) P1DCD TCM Monitoring Processor Performance, Multiple Clutches Locked Up. 6.4L engine (sales code ESG) and equipped with an 8HP70 transmission (sales code DFK) • • • • • • • • • • **Inconsistent 1-2 upshifts when first shifting after a cold soak or in colder ambient temperatures. Delayed engagement when shifting from reverse to drive.** Harsh or inconsistent 1-2 upshift during normal driving. Harsh of inconsistent coasting 4-3 downshift. Harsh or inconsistent gear engagement when shifting to drive or reverse. Instrument Panel Cluster (IPC) shows the incorrect gear when in manual mode. Harsh of inconsistent shifts during tip-in acceleration from closed throttle. Inconsistent gear shift patterns when driving on grades. Inconsistent release of Hill Start Assist during tip-in acceleration. Transmission upshifts on sweeping curves under track driving conditions. **In addition to the above conditions, this software release also enables the capability to capture non Diagnostic Trouble Code (DTC) control module data through the Uconnect Data Recording system.** DIAGNOSIS: Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all vehicle systems are functioning as designed. If DTCs or symptom conditions, other than the ones listed above are present, record the issues on the repair order and repair as necessary before proceeding further with this bulletin. If the customer describes the symptom/condition listed above or if the technician finds the DTC, perform the Repair Procedure. REPAIR PROCEDURE: NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during the flash process. NOTE: If this flash process is interrupted/aborted, the flash should be restarted. 1. Reprogram the TCM with the latest available software. Detailed instructions for flashing control modules using the wiTECH Diagnostic Application are available by selecting the “HELP” tab on the upper portion of the wiTECH window, then “HELP CONTENTS.” This will open the Welcome to wiTECH Help screen where help topics can be selected. 2. Clear all DTCs that may have been set in any module due to reprogramming. The wiTECH application will automatically present all DTCs after the flash and allow them to be cleared. NOTE: Do not clear the adaptation memory cells in the TCM’s memory. Clearing the memory cells may cause the transmission to not shift smoothly until they can be fully relearned. -3- 21-009-15 REV.

TIME ALLOWANCE: Labor Operation No: **18-19-05-AG** Description Skill Category Module, Transmission Control (TCM) - 2- Automatic Reprogram Transmission (0 - Introduction) Amount 0.2 Hrs. NOTE: The expected completion time for the flash download portion of this procedure is approximately 4 minutes. Actual flash download times may be affected by vehicle connection and network capabilities. FAILURE CODE: The dealer must choose which failure code to use. If the customer came in with an issue and the dealer found updated software to correct that issue, use failure code CC, for all other use failure code RF. • • CC - Customer Concern ( Ex.
