MaxxECU DCT control detected an down shift that took to long to complete.
DCT warnings found in DCT --> DCT settings, DCT Warnings.
Note: this is most likely related to that the DCT TCU is unhappy with something...like the engine torque transmitted from MaxxECU to the TCU during a downshift.
The marked area is the torque value used during a downshift (normally if you release the pedal).
Note: Throttle blip is required for the SPORT mode or Drivelogic mode 4,5 and 6, see DCT Control.
