Some 2019-2020 Edge/Nautilus vehicles equipped with an 8F57 transmission may exhibit a harsh engagement when shifting from PARK to REVERSE, PARK to DRIVE and/or REVERSE to DRIVE with no DTCs present. The vehicle may also exhibit a harsh upshift and downshift. These harsh engagements may result in an engagement clunk from the driveline. This may be due to various powertrain control module (PCM) software parameters for harsh engagements when shifting from various shifter selector positions. To correct the condition, follow the Service Procedure to reprogram the PCM.
