Flash: Transmission Control Module (TCM) Updates *Customers must experience a Malfunction Indicator Lamp (MIL) illumination and the vehicle must exhibit/set one or more of the following Diagnostic Trouble Codes (DTCs):
• P1B14-00 - Park By Wire Unintended Park Position.
• P1DF3-00 - ECU Not Initialized.** The customer may describe one or more of the following:
• **Secure idle feature not working with Powerpanel On.
• When shifting from Drive to Reverse and vice versa, the transmission detects a mismatch in Neutral as the gear shifter goes from Drive to Reverse through Neutral (D-N-R or R-N-D) and flashes the Neutral indication blinking on the shifter.
• The gear shifter takes too long to get ready when the driver starts the car, and the transmission system couldn't recognize which gear was selected. This gives a warning message "Shift to Park to Obtain Drivability" in the IPC and MIL lamp On. NOTE: For the condition above, the transmission remains in the Park position.
• Shifter can be moved with engine Off and key On while the transmission is in Park and a warning message is displayed in the IPC "Shift to Park to Start". NOTE: For the condition above, the Electric Park Brake (EPB) is activated.
• Auto parking issue.**
• No perceptible change when drive mode is selected.
• Harsh or unstable launches in slippery or off-road conditions.
• Drive mode operating in incorrect drivetrain configurations.
• Bump or jerk felt during Engine Start/Stop (ESS) operation in normal and snow modes.
• Bump during tip-in downshift while in Normal or Sport modes.
• Transmission shifting concerns when vehicle has less than 2,414 km (1,500 mi).
• Driveability concerns and not holding correct gear during downgrade, snow mode and accelerator tip-out maneuvers. **The following software improvements are also included:
