    6l80 6-4 downshift flare

    On my G8 GT LSA I have a 6-4 mid throttle downshift flare Id like to try and git rid of. I've tried a few things but cant see to get rid of it. My upshifts are great and like the way it shifts.Attachment 1098775-9-21 trans stuff back to payton 00000.hpt

    Log of it happening would be good.

    Are still 6L80?

    Try the following:
    Torque Management -> General -> Torque reduction -> Power downshift = Enabled
    Shift Timing -> Downshift -> Desired Shift Time = Take all 6-4 changes back to stock for fault finding
    Shift Timing -> Downshift -> Torque Adder Normal / Special = Take all 6-4 changes back to stock for fault finding

    The things you have copied special to normal should be fine.
