Some 2019 Edge/Nautilus vehicles equipped with an 8F35 transmission and built on or before 10-Sep-2019 may exhibit a harsh upshift and downshift, harsh engagements when shifting from PARK to REVERSE, PARK to DRIVE and/or REVERSE to DRIVE. 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.
