Flash: Transmission Shift And Drivability Enhancements
This bulletin involves reprogramming the Transmission Control Module (TCM) with the
latest available software.
A small number of customers may experience one or more of the following conditions.
These conditions are only applicable on LD models.
? Less than desired upshift performance during Wide Open Throttle (WOT)
accelerations.
? Less than desired overall downshift performance during coasting deceleration,
braking, or while passing.
In addition to the above conditions, this software release also enables the capability to
capture Electronic Control Unit (ECU) operational data through the Uconnect Data
