A small number of customers may experience one or more of the following conditions. ? Less than desired upshift performance during Wide Open Throttle (WOT) accelerations. ? Less than desired overall downshift performance during coasting deceleration, braking, or while passing. ? Less than desired transmission performance during Multiple Displacement System (MDS) mode transitions. ? Less than desired light or medium throttle shift performance. In addition to the above conditions, this software release also enables the capability to capture Electronic Control Unit (ECU) data through the Uconnect Data Recording system.
